Access Controls Provide A Mechanism
Introduction
Access Controls provide a mechanism, which allows an administrator to ensure that appropriate
techniques are in place to control how users interact with an IT system. It provides an avenue where
restrictions can be developed, specifying what a user can do, the resources they can access, and the
functions they can execute on a system. It is aligned with the three main security principles;
confidentiality, integrity and availability. This alignment ensures that data and resources within an
IT system will remain confidential as required, the structure will remain intact and these objects will
remain available, so as not to diminish the functionality of the system. Access controls that are
incorporated into a security plan are ... Show more content on Helpwriting.net ...
One of the difficulties in managing this access arises from the need to provide a variety of user's
access, each requiring a different type of access to the system. For the sake of security, the need to
manage this access should be defined by one or more of the following frameworks; Role Based
Access Control (RBAC), Discretionary Access Controls (DAC), Mandatory Access Control (MAC),
and Mandatory Access Control (MAC).
Statement of Purpose
The current state of the organization's access control management system is consistent with that of
the DAC model. A recent move to outsource certain business practices and continued organizational
growth has created an environment where increases in employee hiring's and employee turnover are
inevitable. An analysis of various methods of access control has been requested, so that we can
better understand how specific access control attacks are perpetrated and their origin. Information
will be collected and then analyzed in order to substantiate any recommended changes to the current
access control configurations. RBAC, DAC, and MAC will be compared and contrasted, in order to
gain insight, as to how each plays a role in reducing the risk to a system, along with identifying the
strengths and weaknesses of each. These results, along with a detailed recommendation will be
presented to executive management, in order to generate the necessary support for altering the

Access Control Lists
Introduction –
This report will look at various access control methods used by Operating Systems (OS) to control
user access to files on a computer and what they can do once they have gained access. In this first
section I will look at methods such as Access Control Lists(ACL's), Capabilities and Encrypting file
systems(EFS) and which Operating Systems use these as well as the advantages and disadvantages
they have over each other. The second part of my report will focus on one OS and explain in detail
the methods it uses to control file access and how it works.

Unlike UNIX ACL's, the order that entities are listed in the DACL for Windows is important, if a
group is denied access to an object, however one individual belonging to that group is allowed
access, then it is important to list the individual as being allowed access on the DACL before listing
the group to be denied. If it is done the opposite way around, then when the system checks the
DACL it will straight away deny the whole group, including the user that is allowed, similarly it
would be possible, if a group was allowed access but one individual was denied, to accidentally
allow the individual to gain access. Because of this flaw, DACL's must be carefully thought out
when the administrator is configuring it (Microsoft: 2008). Access Control Lists have the advantage
that they work well with commonly used systems, such as windows where there may be a number of
users where access needs to be regulated, they do however have a downside, if somebody is able to
gain access to the administrative part of the system they have full permissions, another flaw is that if
the administrator fails to grant permissions correctly they could leave the whole system open to
everybody, or block out all the users. With both UNIX and Windows, when ACL's are applied to
something such a directory, the permissions only applies for what is within a directory. If a file is
moved to a new directory it will adopt the new permissions, subdirectories

Access Controls And Access Control Security Essay
INTRODUCTION
As the use of computers, databases, and technology in general, security has grown to be a powerful
tool that has to be used. The threat of outside sources intruding and exploiting crucial information is
a threat that is present on a daily basis. As a part of creating and implementing a security policy, a
user must consider access control. Access Control is a security tool that is used to control who can
use or gain access to the protected technology. Access control security includes two levels; logical
and physical. Though database intrusions can happen at any moment, access control provides
another security barrier that is needed. Access control has been in use before the growth of the
technology world. It could involve a simple action as locking a door. A person locks a door to
prevent entry to those who are not allowed or authorize to do so. The same can be said about the
security involving databases and the controlling of who can have access and what can be accessed.
As far as database security is concerned, there are various categories that are involved in access
control. The four main categories of access control include: Discretionary, Mandatory, Role–based,
and Rule–based access control. According to Rouse (2006), "Computer databases typically contain
aggregations of data records or files, such as sales transactions, product catalogs and inventories,
and customer profiles" (Rouse, 2006). Databases can hold a sufficient of information that are

Access Control For Access Controls
Access control is simply a method that allows or denies the right to use to resources that is deemed
to have a value worth protecting. Access controls define exactly who can interact with what,
regarding what the subject may do during the interaction session. The basis is granting rights and
privileges to a subject with respect to an object.
Access controls must be rooted in good policies and procedures with strong tools to implement
them. To ensure complete protection of resources access controls are split up into two different
phases. The first phase is about forming a strong access control policy to layout the ground work for
the rest of the organizations policies .This phase of access controls should at least address which
subjects have access to varying degrees of sensitive systems and data, for what reason, and for how
long. Authorization is the process that drives the operation of this phase. Policy enforcement is the
next phase granting or rejecting access based on authorization of the policy definition phase. To
guarantee enforcement of policies this phase is split up into three distinct operations: identification,
authentication, and accountability.
Well–reasoned authorization is the fundamental building blocks of formidable access controls.
Regulating the access to resources is crucial for the success of an organization. Developing clear and
concise policies will insure the prevention of security breaches from happening, as long as they
firmly adhered to. These

Access Controls And Access Control
This chapter is basically based on access control in regards to computer information security. Access
control is seen as the fundamental mechanism put in place to help make information security
successful. Access control feature, in a particular system, will control how users can communicate,
access and modify system resources and programs. Access control was described in this chapter as a
very useful tool for the computer information security because it helps with ensuring that
unauthorized person or program have no access to what they are not supposed to. Access control is
regarded as the first line of defense to control, protect and monitor organization's resource's
availability, confidentiality and integrity.
Furthermore, this chapter illustrates how users can be granted access to network resources. It
explained that for a user to be allowed access to a network he must satisfy the condition of
identification and authentication. The identification part could be something of user ID, name or
account number. The identification key is not enough to grant access, but it's simply a way of
introducing yourself by saying who you are. Then, at that point the system will request for you to
authenticate yourself (confirm who you said you are) by requesting for an authentication key. The
authentication key could be password, passphrase, personal identification number (PIN), or a token.
Once, the authentication is verified and the system found it to be correct, then access will be

Implementing Access Control Third L
Operating System Security
Introduction
An operating systems (OS) serves as the medium between the user of a computer and the hardware
that it resides on. The operating system manages how programs communicate with resources in a
computer, such as disk drives, microprocessor, CPU kernel, RAM ,usb external drives, network
interfaces, printers, and web cameras to name a few. Operating systems interact with application's
that are built by programmers in house or commercial off the shelf (COTS) such as Microsoft Office
Suite or Symantec Antivirus software. The information store on computers are essential to our way
of live. Protecting this information from malicious intruders is not always practice by IT
professional in an organization until it is too late.
The steps to ensure that information is protected is the basis for this paper. I will cover protecting
the operating systems through security concepts. First, I will explain the process of protecting

Access Control List : Lab Analysis
An ACL also was known as Access Control List is a type of well–ordered list that works by denying
or permitting statements (UMUC, 2012). A reference to an ACL by a network device allows the
reading of the list from top to bottom. The placement order for the ACL statements is very critical.
The ACL entries below are ideal entries when made use of. Research shows that there are various
ACL entries that are most ideal for use. This essay will discuss these entries, their variations and
their effects. "Access–list 101 deny TCP 192.168.2.0.0.0.255 192.168.3.3 0.0.0.0 any log" is the
initial known decree. All sorts of traffic from the whole classified LAN are subject to being blocked

"Alert IP 192.168.2.0/24 –> 192.168.3.3 999 (message: Potential Read Up Release"; sid: 9999998;)"
is a decree that has the potential to read the private info on the receiver of a text message to detects
all the attempts from all the devices.
Conclusion
Any sort of data manipulation between the sender and user end starts from somewhere. Various
protocols can then be laid down to ensure that any Trojans activity that target this data have been
curbed. If the decrees that are laid in place are followed, the programmer can then come up with a
way of keeping the data secure from being pried on thus ensuring its security.

the unique advantage of 100% endpoint visibility, automated triage, and automated quarantine of
suspicious devices. Our proven solution is helping more than 1,000 organizations, including Atrius
Health, UC Irvine Health and US Health Group. While there are many endpoint security solutions,
there are a number of key features healthcare organizations should require to ensure a strong
security posture and HIPAA compliance. Here is a checklist of important security features:
1) Complete endpoint visibility. Ensure that the solution can see and profile every single endpoint. If
you cannot see an endpoint, you cannot track all the actions. A complete audit trail is critical for
historical forensic evidence and HIPAA compliance. Network Sentry was developed to provide
comprehensive visibility.
2) Enforce minimum security programs and patches for endpoint devices before they connect to the

A Brief Note On Access Control Access Controls
Thus majority of the respondents think frequent change of password is necessary but not
manageable which indicate usability issues like inability to create passwords as frequently as
obligatory. Inglesant and Sasse (2010) found that end–users experience with password security
policy is that of rigidity in regards to their skills and official responsibilities.
Inglesant and Sasse (2010) also found an improvement in the number of their respondents that is 9
out of 32 respondents wrote down their passwords as end–users are more aware of data security.
Access control limit access to sensitive data based on organisation policies by determining who and
how data can be accessed based on a "need to know" of an entity like an employee's name, position
or something you are like fingerprints (Goodrich and Tamassia 2011, Kizza 2010). Additionally
identity depends on other characteristics such as something you are acquainted with like password
and something you have like secret encryption key. Access control is based on the assumption that
only the authorized entity has possession of what they are, know or have (Shabtai, Yuval and
Rokach 2012).
However access control is limited in preventing data leakage due to social engineering and
networking. This have led to recent development of using more than one form of access control in a
process called layered authentication like audio–visual interfaces (Jang–Jaccard and Nepal 2014).

There are entrances to the college which are not guarded by security personnel. There is no proper
barrier around the institution which makes the posting of security personnel at the main gates
insignificant. Trespassers gain access to the college residential areas and learning centres to
vandalize college property.
Trespassers cut the padlocks with bolt cutters and open them. Keys are duplicated and used to gain
access to restricted areas and they are habitually lost as they are relatively small in size. Once a key
is reported missing or duplicated, the door locking mechanism has to be replaced which costs the
college dearly as several locking points are replaced each year.
This research seeks to investigate the implementation of a magnetic access control card security
system within the SCOT community. It aims is to lessen the problems of security experienced in the

Basic Concepts Of Access Control System
In any given social network, the number of users might be significant, the number of resources that
must be protected might be in millions, and hence the number of access control policies that need to
be defined might be in billions. If only one permission is incorrectly granted, a user will be given
unsupervised access to information and resources which could jeopardize the security of the entire
given social network.

Hence, the following metrics are classified based upon the four categories mentioned above:
1. Ability to combine several related rules. The PBAAC decision engine is able to collect different
access control rules, consolidate similar rules and derive a result under the specified condition.
These rules can be defined by the controlling user, the target user, and the supervisor of the social
network.
2. Ability to combine access control models. Under our approach, two access control models are
combined, namely ABAC and PBAC models. By using the ABAC model, access constraints will be
defined for each entity, and by using PBAC, policies enforcing access to a resource will be defined.
Under our model, policies will be defined by controlling user, the target user, or the supervisor of
the social network.
3. Ability to enforce the least privilege principle. Our model includes an entity as supervisor who is
the administrator of the social network. The minimum privilege principle will be provided by rules
defined by the supervisor. Our model accepts new users with various associated attributes. In order

would be having mandatory training before getting access to a certain room. If you do not complete
the training, then you will not have access. Other examples of administrative access controls include
personnel registration, recovery plans, and disaster preparedness. Physical access controls are "the
implementation of security measures in a defined structure used to deter or prevent unauthorized
access to sensitive material "and include restricted access rooms that require a badge, password, or
some other special permission to enter (Red Hat, n.d.). An example of this would be not related to
computers is a barhop standing at the door making sure only 21+ adults enter. In a computer or

passphrase to be granted access into the otherwise locked room. Technical access controls use
"technology as a basis for controlling the access and usage of sensitive data throughout a physical
structure and over a network " (Red Hat, n.d.). They include "tools used for identification,

Understanding the importance of access controls and audit controls are two of the main steps for

important steps in addressing ways to maintain and utilize the access controls are authentication,
authorization, and audit (Gelzer, Acker, & Schneider, 2008). Authentication is used differently

Professor M. Hansen
In order to establish system design controls that are directly related to the data input mechanism of a
network and in order to control data entry operations and prevent unauthorized access to information
or data; Role Based Access Controls (RBAC) are required. The basic principle of these controls is
that the data entry personnel, on any level, should be allowed limited access to only specific
information in order to get their jobs done. Because of higher data requirements, more data access
streams, higher employee turnover and outsourcing of data–entry processes there are many avenues
where data can acquired illegally from an outside source and within the organization ... Show more

In many applications, RBAC is concerned more with access to functions and information than
strictly with access to information. (Gupta, 2004)
The Common Criteria also note the following: "security policies defined for systems ... used to
process classified or other sensitive information must include provisions for the enforcement of
discretionary access control rules. That is, they must include a consistent set of rules for controlling
and limiting access based on identified individuals who have been determined to have a need–to–
know for the information." (Kim, 2012) The date input control is another challenge, When you have
several people entering data in your database, you can define how users must enter data in specific
fields to help maintain consistency and to make your database easier to manage. Role based input
control provides data input control. Free text input control, though unavoidable in forms that need
information from the user; should avoid using text boxes and text areas as much as possible. It can
be difficult for the user to enter content into free text input controls such as text boxes and text areas.
Instead, rely on radio buttons, select boxes, and even lists of links. Check boxes are a commonly
used input control; a check box is a small square box that allows the user to select an item or to

security classification levels with robust enforcement. Originally, the term MAC denoted that the
access controls were not only guaranteed in principle, but in fact. Early security strategies[2]
enabled enforcement guarantees that were dependable in the face of national lab level attacks.
More recently, with the departure from strict hardware–based enforcement the expectations of the
term "mandatory" has become more relaxed, migrating from mandating near absolute enforcement
to acceptance of "best effort" enforcement. While software–based enforcement is more flexible, the
security technology has not yet produced a software–based enforcement strategy that can enforce a
policy with near certainty. This is because it has been much more difficult to be certain about what a
software–based system will never do compared to that of hardware–based system. With software–

work to secure information systems
1.1. Authentication
Describe how and why authentication credentials are used to identify and control access to files,
screens, and systems. Include a discussion of the principles of authentication such as passwords,
multifactor authentication, biometrics, and single–sign–on.
Authentication credentials are used to control access to sensitive data or systems by making it hard
for people to get into the system who shouldn't have access. Passwords and usernames are a good
start because if they are kept secure, they are generally very hard to bypass. If they are bypassed by

1.2.2. Mandatory access control
Describe how and why mandatory access control will be used.
Mandatory access is used to authenticate actions between a subject and an object. In order for a
subject to access an object it must pass a set of authentication rules.
1.2.3. Role–based access control
Describe how and why role–based access control will be used.
RBAC is a very efficient way to control access to resources. This is because access is granted to
select roles based on what the needs each role has to complete its job. Then, the person or program
is assigned to the role and thus will only be granted the access granted to the role they are assigned.

Describe the policies for remote user access and authentication via dial–in user services and Virtual
Private Networks (VPN)
The policies for remote access, authentication via dial–in user services, and VPN's has to be more
strict than with general authentication and access within the work place. While there are ways for a
hacker to get into the system while following the usual work place policies, it would probably be
much easier to get in by one of these methods. When accessing resources remotely it is important to
have added authentication methods such as security questions or possibly some kind of portable

Access Control System : Access Controls System
Access Control System
The access control system is a fundamental way of reducing security problems and control the
access of people to a place. The purpose of the access control is to make sure that the right people
are only granted the access to the place. The control system will ensure the privilege for people to
access the building according to their rights and level. The control system monitor and record all the
activities regarding the access control to lock and unlock the building, detect when a pass card is
used and used when it has been declared lost. (Benantar, 2006)
Improving the security system of the dormitory is important by creating an access control system to
lock and unlock the doors automatically through an electronic device reader that will allow visitors
during entry and required personnel. To correct insecurity, it is very important that the security
system be improved to discover the visitors that came in and to only allow the required staffs into
the system. Hence, our objective is to create an access control system that open and close the door
automatically through an electronic reader.
The system should be connected with the security camera system to enhance effective operation.
The access control system would require that all visitors swipe their cards through the card reader
and the system would check if the information on the card matches with information in the database;
then, if a match is found, the door would open (Sandhu & Munawer, 2002).

Basic Methods Of Access Control
Abstract
Physical security entails restricting physical access to controlled buildings, installations,
information, facilities, and personnel by unauthorized individuals. Access control may prevent
potential intruders, delay or frustrate intruders, and monitor and detect intruders. These methods are
classified under physical barriers, perimeter security, identification systems, and
electronic/mechanical barriers. Different methods of access control can be designed to respond to
different physical security needs. However, it is worth to note that no stand–alone method of access
control is effective and thus to improve effectiveness and performance, two or more methods should
be used in combination. This paper examines various methods of access control and their
effectiveness in relation to the physical security.
Introduction Controlling access is an important component of physical security to protect assets and
material resources. Making sure that only authorized vehicles, items, and people enter and exit
defined areas minimizes the risk of harm or loss to all assets (Fennelly, 2012). Physical security
entails security measures which are tailored to deny an unauthorized access to material resources,
such as buildings, critical installations, personnel, and information from terrorism, espionage, and
other criminal activities. Physical protection of material resources is intended to prevent potential
intruders, detect intruders, and trigger apt incident

Implementing Physical Security As An Access Control Plan
Implementing physical security as an access control plan takes a great effort of planning. Physical
security is the protection and controlled access of personnel, the environment they operate in, which
includes the hardware and what it contains, as well as the rooms and buildings they are located in.
Physical security has three indispensable parts: access to control, observation, and testing. Obstacles
should be set for potential aggressors and physical areas should be bolstered against anything
causing delays, attacks or natural disasters. Such measures can include proper fencing, locks, control
access cards, biometrics that control systems and fire proofing structures. Physical areas should be
checked using observation cameras and for ... Show more content on Helpwriting.net ...
A clear and concise plan is needed, which will help lessen potential threats. The foundation of
biometric sensors, for instance, iris inspecting or one of a kind finger impression affirmation, can
make even the most formidable intruder think twice about gaining unauthorized access. Now and
again, all that is relied upon to decide the issue is an instrument to give enough time to contact the
authorities. In any case, access control should consist of physical security as well as information
security (Ricardo, 2015).
Consideration should be given to shutting off access to portable workstations, desktops, and servers.
There is great risk for a potential insider threat, such as personnel leaving the workplace undetected
with a portable device tucked under a clothing item. Such circumstances happen extremely often
and more organizations are being compromised. One conceivable situation to fix security is to
utilize the terminal server and a bootable Linux conveyance. Likewise avoided are DHCP (Dynamic
Host Configuration Protocol), anticipating issues with spyware, malware, or infections (Ricardo,
2015).

Application Of Access Control System
Introduction
Access control is one of the earliest problems in computer security and remains a continuing
challenge. Access control component determines whether requests to access resources are granted.
1. Discretionary access control
In Discretionary Access Control any user can set an entrance control instrument to permit or deny
access to an object. DAC relies on the object proprietor to control access. It is generally executed in
most working frameworks, and is very familiar access control method. Flexibility is a strength of
DAC and a key motivation behind why it is broadly known and actualized in standard working
frame.
Unlike Mandatory Access Control (MAC) where access to framework assets is controlled by the
working framework ... Show more content on Helpwriting.net ...
A discretionary access control (DAC) arrangement is a method for appointing access rights in light
of tenets predetermined by clients. This class of approaches incorporates the record consents model
actualized by almost every single working framework. In Unix, for instance, a catalog posting may
yield "... rwxr–xr–x ... file.txt", implying that the proprietor of file.txt may read, compose, or
execute it, and that different clients may read or execute the document yet not compose it. The
arrangement of access rights in this case is {read, compose, execute}, and the working framework
intercedes all solicitations to perform any of these activities. Clients may change the consents on
documents they possess, making this an optional strategy.
A system actualizing a DAC approach must have the capacity to answer the inquiry: "Does subject S
have right R for item O?" Abstractly, the data expected to answer this inquiry can be spoken to as a
scientific connection D on subjects, protests, and rights: if (S, O, and R) is in D, then S has right R
for article O; generally, S does not. All the more basically, the same data could likewise be spoken to
as an entrance control network. Every column of the grid relates to a subject and every segment to
an article. Every cell of the framework contains an arrangement of rights.

Discretionary Access Control (DAC)
Discretionary Access Control (DAC)
Computer security is important in every organization. It covers several areas such as locking the
computer room and the computer itself, protecting login accounts with passwords, encrypting
network communication lines and use of file protection among others. Whitman (2011) points out
that computer system security ensures that your computer does what it is supposed to, even if the
users do what they should not do. Discretionary Access Control (DAC) is a type of access controls
that provides protection to the files in a computer system. This type of control restricts access to
files based on the identity of users or groups which they belong. It is discretionary and lets you tell
the computer system who can have access to your files and therefore you can specify the type of
access allowed. For example, you can allow anyone to read a particular file in the system, but allow
only you to be able to change it.
According to Whitman (2011), this type of control access is rarely used with high security systems
because someone with permission to access files is able to pass that permission either directly or
indirectly on to any other person. This capability poses a threat to the security of the files and can be
dangerous to a high security system. An organization that requires high security, but the operating
system only supports DAC, can compensate with the use of an Access Control List (ACL). Haldar

The Access Control System For Providing Physical Security
TO PROVIDE PHYSICAL SECURITY?
Introduction
In the present world, the Access Control System is used in all the places where it is intended that a
system should allow the authorized persons to get in or leave the facilities as and when required and
also to keep a record about these movements. Basically it determines who is allowed to enter or exit;
similarly allowed to exit or enter even with the time when they are allowed to enter or exit. In the
past, the same job could have been partially done by locks and keys. But there were number of
limitations of the mechanical locks & keys. Firstly, it did not provide any restriction to the key
holders to specific times & dates. Secondly, it did not provide any records of the key used to a
specific door. Thirdly, the keys can be easily copied or transferred to the unauthorized person.
Finally, when the key is lost, the authorized person losses his access to the protected areas and the
locks must be re–keyed.
Electronic Access Control System has come forward to solve the problems of mechanical locks &
keys. The system uses a computer network where a wide range of credentials or identifications are
used to replace those mechanical keys. In the system, when the credentials are provided then the
access is granted; the door is unlocked for a predetermined time and the transaction is recorded.
Again, when the access is denied, the door remains locked and the attempted access are also
recorded. The system can also monitor the door and

It is also possible under some operating systems for the network or system administrator to dictate

Control has a more flexible environment than Mandatory Access Control, but also increases the risk
that data will be made accessible to users who should not gain access. Understanding permissions
about the security of file servers on the network will increase network security (Bushmiller, 2011).
2 Mandatory access control
Describe how and why mandatory access control will be used.
Mandatory Access Control (MAC) uses a hierarchy approach to control access to resources, such as
data files. The system administrator is responsible for the settings in a MAC environment. All access
to resource objects is controlled by the operating system based on setting configured by the system
administrator. With MAC it is not possible for users to change the access control for any resource.
Mandatory Access Control starts with security labels, which contain two types of information and
are assigned to all resource objects on the system. The two types of information are classification,
such as confidential or top secret and a category, which is basically an indication of the project or
department to which the object is available, or an indication of the management level.

from your access points will be stored on a local server. This could be a server located on–site or a
remotely located server. With server–based storage, only an individual who has access to your server
will be able to access the entry and exit information for your business.
If security is a concern for you, a server based system to store information about who accesses your
building is the way to go. If having access to that information regardless of where you are at is
important to you, a browser based information storage system may be best.

Inadequately secured wireless communication
"Wireless security isn't just a big issue for control systems, but for all uses, mainly because wireless
is becoming so pervasive," says Staggs. "It's very easy to plug wireless in almost anywhere.
However, you have to be able to find the signals and know if someone has put in a rogue point.
"Before installing wireless, it's important to do a complete assessment to identify the best areas for
wireless use and ensure that leakage out of the plant is minimized. There will be a wireless leakage
when you have transmitters or wireless–enabled workers walking around with tablet PCs or
handheld devices. Those devices may be transmitting in an area outside a plant."
Solution can be separation by segmenting the wireless networks from the rest of the control
network. Additionally, it is strongly advisable to secure wireless access methods to include requiring
authentication and enforcing strict access controls for communications leading from the wireless
network into the rest of the control network.

Access Controls Provide A Mechanism

  • 1. Access Controls Provide A Mechanism Introduction Access Controls provide a mechanism, which allows an administrator to ensure that appropriate techniques are in place to control how users interact with an IT system. It provides an avenue where restrictions can be developed, specifying what a user can do, the resources they can access, and the functions they can execute on a system. It is aligned with the three main security principles; confidentiality, integrity and availability. This alignment ensures that data and resources within an IT system will remain confidential as required, the structure will remain intact and these objects will remain available, so as not to diminish the functionality of the system. Access controls that are incorporated into a security plan are ... Show more content on Helpwriting.net ... One of the difficulties in managing this access arises from the need to provide a variety of user's access, each requiring a different type of access to the system. For the sake of security, the need to manage this access should be defined by one or more of the following frameworks; Role Based Access Control (RBAC), Discretionary Access Controls (DAC), Mandatory Access Control (MAC), and Mandatory Access Control (MAC). Statement of Purpose The current state of the organization's access control management system is consistent with that of the DAC model. A recent move to outsource certain business practices and continued organizational growth has created an environment where increases in employee hiring's and employee turnover are inevitable. An analysis of various methods of access control has been requested, so that we can better understand how specific access control attacks are perpetrated and their origin. Information will be collected and then analyzed in order to substantiate any recommended changes to the current access control configurations. RBAC, DAC, and MAC will be compared and contrasted, in order to gain insight, as to how each plays a role in reducing the risk to a system, along with identifying the strengths and weaknesses of each. These results, along with a detailed recommendation will be presented to executive management, in order to generate the necessary support for altering the current program ...

Access Control Lists Introduction – This report will look at various access control methods used by Operating Systems (OS) to control user access to files on a computer and what they can do once they have gained access. In this first section I will look at methods such as Access Control Lists(ACL's), Capabilities and Encrypting file systems(EFS) and which Operating Systems use these as well as the advantages and disadvantages they have over each other. The second part of my report will focus on one OS and explain in detail the methods it uses to control file access and how it works. Section A – Review of File Access Control mechanisms. Access Control Lists – Access Control Lists are used by ... Show more content on Helpwriting.net ... Unlike UNIX ACL's, the order that entities are listed in the DACL for Windows is important, if a group is denied access to an object, however one individual belonging to that group is allowed access, then it is important to list the individual as being allowed access on the DACL before listing the group to be denied. If it is done the opposite way around, then when the system checks the DACL it will straight away deny the whole group, including the user that is allowed, similarly it would be possible, if a group was allowed access but one individual was denied, to accidentally allow the individual to gain access. Because of this flaw, DACL's must be carefully thought out when the administrator is configuring it (Microsoft: 2008). Access Control Lists have the advantage that they work well with commonly used systems, such as windows where there may be a number of users where access needs to be regulated, they do however have a downside, if somebody is able to gain access to the administrative part of the system they have full permissions, another flaw is that if the administrator fails to grant permissions correctly they could leave the whole system open to everybody, or block out all the users. With both UNIX and Windows, when ACL's are applied to something such a directory, the permissions only applies for what is within a directory. If a file is moved to a new directory it will adopt the new permissions, subdirectories ... Get more on HelpWriting.net ...

  • 5. Access Controls And Access Control Security Essay INTRODUCTION As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed. Access control has been in use before the growth of the technology world. It could involve a simple action as locking a door. A person locks a door to prevent entry to those who are not allowed or authorize to do so. The same can be said about the security involving databases and the controlling of who can have access and what can be accessed. As far as database security is concerned, there are various categories that are involved in access control. The four main categories of access control include: Discretionary, Mandatory, Role–based, and Rule–based access control. According to Rouse (2006), "Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles" (Rouse, 2006).

  • 7. Access Control For Access Controls Access control is simply a method that allows or denies the right to use to resources that is deemed to have a value worth protecting. Access controls define exactly who can interact with what, regarding what the subject may do during the interaction session. The basis is granting rights and privileges to a subject with respect to an object. Access controls must be rooted in good policies and procedures with strong tools to implement them. To ensure complete protection of resources access controls are split up into two different phases. The first phase is about forming a strong access control policy to layout the ground work for the rest of the organizations policies .This phase of access controls should at least address which subjects have access to varying degrees of sensitive systems and data, for what reason, and for how long. Authorization is the process that drives the operation of this phase. Policy enforcement is the next phase granting or rejecting access based on authorization of the policy definition phase. To guarantee enforcement of policies this phase is split up into three distinct operations: identification, authentication, and accountability. Well–reasoned authorization is the fundamental building blocks of formidable access controls. Regulating the access to resources is crucial for the success of an organization. Developing clear and concise policies will insure the prevention of security breaches from happening, as long as they firmly adhered to. These ... Get more on HelpWriting.net ...

  • 9. Access Controls And Access Control This chapter is basically based on access control in regards to computer information security. Access control is seen as the fundamental mechanism put in place to help make information security successful. Access control feature, in a particular system, will control how users can communicate, access and modify system resources and programs. Access control was described in this chapter as a very useful tool for the computer information security because it helps with ensuring that unauthorized person or program have no access to what they are not supposed to. Access control is regarded as the first line of defense to control, protect and monitor organization's resource's availability, confidentiality and integrity. Furthermore, this chapter illustrates how users can be granted access to network resources. It explained that for a user to be allowed access to a network he must satisfy the condition of identification and authentication. The identification part could be something of user ID, name or account number. The identification key is not enough to grant access, but it's simply a way of introducing yourself by saying who you are. Then, at that point the system will request for you to authenticate yourself (confirm who you said you are) by requesting for an authentication key. The authentication key could be password, passphrase, personal identification number (PIN), or a token. Once, the authentication is verified and the system found it to be correct, then access will be ... Get more on HelpWriting.net ...

A reference to an ACL by a network device allows the reading of the list from top to bottom. The placement order for the ACL statements is very critical. The ACL entries below are ideal entries when made use of. Research shows that there are various ACL entries that are most ideal for use. This essay will discuss these entries, their variations and their effects. "Access–list 101 deny TCP 192.168.2.0.0.0.255 192.168.3.3 0.0.0.0 any log" is the initial known decree.

"Alert IP 192.168.2.0/24 –> 192.168.3.3 999 (message: Potential Read Up Release"; sid: 9999998;)" is a decree that has the potential to read the private info on the receiver of a text message to detects all the attempts from all the devices. Conclusion Any sort of data manipulation between the sender and user end starts from somewhere. Various protocols can then be laid down to ensure that any Trojans activity that target this data have been curbed. If the decrees that are laid in place are followed, the programmer can then come up with a way of keeping the data secure from being pried on thus ensuring its security.

A Brief Note On Access Control Access Controls Thus majority of the respondents think frequent change of password is necessary but not manageable which indicate usability issues like inability to create passwords as frequently as obligatory. Inglesant and Sasse (2010) found that end–users experience with password security policy is that of rigidity in regards to their skills and official responsibilities. Inglesant and Sasse (2010) also found an improvement in the number of their respondents that is 9 out of 32 respondents wrote down their passwords as end–users are more aware of data security. Access control limit access to sensitive data based on organisation policies by determining who and how data can be accessed based on a "need to know" of an entity like an employee's name, position or something you are like fingerprints (Goodrich and Tamassia 2011, Kizza 2010). Additionally identity depends on other characteristics such as something you are acquainted with like password and something you have like secret encryption key. Access control is based on the assumption that only the authorized entity has possession of what they are, know or have (Shabtai, Yuval and Rokach 2012). However access control is limited in preventing data leakage due to social engineering and networking. This have led to recent development of using more than one form of access control in a process called layered authentication like audio–visual interfaces (Jang–Jaccard and Nepal 2014).

Magnetic access control card system is one of the many ways of restricting access to a building or area. According to Oke et al. (2009), magnetic access control systems are used to control entry to a room or building and were developed to reduce prodigious amount of theft and fraud. Magnetic access control card security systems use smart cards which are small plastic cards made out of Polyvinyl Chloride incorporating one or more integrated circuits within its thickness to store and transact data (Hendry, 2007). Types of smart cards include Subscriber Identity Modules (SIM) cards, magnetic ... Show more content on Helpwriting.net ... There are entrances to the college which are not guarded by security personnel. There is no proper barrier around the institution which makes the posting of security personnel at the main gates insignificant. Trespassers gain access to the college residential areas and learning centres to vandalize college property. Trespassers cut the padlocks with bolt cutters and open them. Keys are duplicated and used to gain access to restricted areas and they are habitually lost as they are relatively small in size. Once a key is reported missing or duplicated, the door locking mechanism has to be replaced which costs the college dearly as several locking points are replaced each year. This research seeks to investigate the implementation of a magnetic access control card security system within the SCOT community. It aims is to lessen the problems of security experienced in the college. Research Motivation The motivation behind this research project is driven by the number of shortfalls of the security system currently used at SCOT. There have been numerous security breach reports of the current system and the breaches were attributed to the weaknesses of the current system. 3.1.

The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed. Access control has been in use before the growth of the technology world. It could involve a simple action as locking a door. A person locks a door to prevent entry to those who are not allowed or authorize to do so. The same can be said about the security involving databases and the controlling of who can have access and what can be accessed. As far as database security is concerned, there are various categories that are involved in access control. The four main categories of access control include: Discretionary, Mandatory, Role–based, and Rule–based access control. According to Rouse (2006), "Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles" (Rouse, 2006).

The PBAAC decision engine is able to collect different access control rules, consolidate similar rules and derive a result under the specified condition. These rules can be defined by the controlling user, the target user, and the supervisor of the social network. 2. Ability to combine access control models. Under our approach, two access control models are combined, namely ABAC and PBAC models. By using the ABAC model, access constraints will be defined for each entity, and by using PBAC, policies enforcing access to a resource will be defined. Under our model, policies will be defined by controlling user, the target user, or the supervisor of the social network. 3. Ability to enforce the least privilege principle. Our model includes an entity as supervisor who is the administrator of the social network. The minimum privilege principle will be provided by rules defined by the supervisor. Our model accepts new users with various associated attributes.

An example would be having mandatory training before getting access to a certain room. If you do not complete the training, then you will not have access. Other examples of administrative access controls include personnel registration, recovery plans, and disaster preparedness. Physical access controls are "the implementation of security measures in a defined structure used to deter or prevent unauthorized access to sensitive material "and include restricted access rooms that require a badge, password, or some other special permission to enter (Red Hat, n.d.). An example of this would be not related to computers is a barhop standing at the door making sure only 21+ adults enter. In a computer or business example, this could be only letting the IT guy have access to the data center. He would have either a special card to let him in or he would have to make a phone call and use a special passphrase to be granted access into the otherwise locked room. Technical access controls use "technology as a basis for controlling the access and usage of sensitive data throughout a physical structure and over a network " (Red Hat, n.d.).

Hansen In order to establish system design controls that are directly related to the data input mechanism of a network and in order to control data entry operations and prevent unauthorized access to information or data; Role Based Access Controls (RBAC) are required. The basic principle of these controls is that the data entry personnel, on any level, should be allowed limited access to only specific information in order to get their jobs done. Because of higher data requirements, more data access streams, higher employee turnover and outsourcing of data–entry processes there are many avenues where data can acquired illegally from an outside source and within the organization ... Show more content on Helpwriting.net ... In many applications, RBAC is concerned more with access to functions and information than strictly with access to information. (Gupta, 2004) The Common Criteria also note the following: "security policies defined for systems ... used to process classified or other sensitive information must include provisions for the enforcement of discretionary access control rules. That is, they must include a consistent set of rules for controlling and limiting access based on identified individuals who have been determined to have a need–to– know for the information." (Kim, 2012) The date input control is another challenge, When you have several people entering data in your database, you can define how users must enter data in specific fields to help maintain consistency and to make your database easier to manage. Role based input control provides data input control. Free text input control, though unavoidable in forms that need information from the user; should avoid using text boxes and text areas as much as possible. It can be difficult for the user to enter content into free text input controls such as text boxes and text areas. Instead, rely on radio buttons, select boxes, and even lists of links. Check boxes are a commonly used input control; a check box is a small square box that allows the user to select an item or to deselect it.

Early hardware–based enforcement implementations of MAC such as Honeywell's SCOMP, USAF SACDIN, NSA Blacker, and Boeing's MLS LAN focused on MLS to protect military–oriented security classification levels with robust enforcement. Originally, the term MAC denoted that the access controls were not only guaranteed in principle, but in fact. Early security strategies[2] enabled enforcement guarantees that were dependable in the face of national lab level attacks. More recently, with the departure from strict hardware–based enforcement the expectations of the term "mandatory" has become more relaxed, migrating from mandating near absolute enforcement to acceptance of "best effort" enforcement. While software–based enforcement is more flexible, the security technology has not yet produced a software–based enforcement strategy that can enforce a policy with near certainty.

Role–based access control Describe how and why role–based access control will be used. RBAC is a very efficient way to control access to resources. This is because access is granted to select roles based on what the needs each role has to complete its job. Then, the person or program is assigned to the role and thus will only be granted the access granted to the role they are assigned. 1.3.

Basic Methods Of Access Control Abstract Physical security entails restricting physical access to controlled buildings, installations, information, facilities, and personnel by unauthorized individuals. Access control may prevent potential intruders, delay or frustrate intruders, and monitor and detect intruders. These methods are classified under physical barriers, perimeter security, identification systems, and electronic/mechanical barriers. Different methods of access control can be designed to respond to different physical security needs. However, it is worth to note that no stand–alone method of access control is effective and thus to improve effectiveness and performance, two or more methods should be used in combination. This paper examines various methods of access control and their effectiveness in relation to the physical security. Introduction Controlling access is an important component of physical security to protect assets and material resources. Making sure that only authorized vehicles, items, and people enter and exit defined areas minimizes the risk of harm or loss to all assets (Fennelly, 2012).

In any case, access control should consist of physical security as well as information security (Ricardo, 2015). Consideration should be given to shutting off access to portable workstations, desktops, and servers. There is great risk for a potential insider threat, such as personnel leaving the workplace undetected with a portable device tucked under a clothing item.

A discretionary access control (DAC) arrangement is a method for appointing access rights in light of tenets predetermined by clients. This class of approaches incorporates the record consents model actualized by almost every single working framework. In Unix, for instance, a catalog posting may yield "... rwxr–xr–x ... file.txt", implying that the proprietor of file.txt may read, compose, or execute it, and that different clients may read or execute the document yet not compose it. The arrangement of access rights in this case is {read, compose, execute}, and the working framework intercedes all solicitations to perform any of these activities. Clients may change the consents on documents they possess, making this an optional strategy. A system actualizing a DAC approach must have the capacity to answer the inquiry: "Does subject S have right R for item O?" Abstractly, the data expected to answer this inquiry can be spoken to as a scientific connection D on subjects, protests, and rights: if (S, O, and R) is in D, then S has right R for article O; generally, S does not.

It covers several areas such as locking the computer room and the computer itself, protecting login accounts with passwords, encrypting network communication lines and use of file protection among others. Whitman (2011) points out that computer system security ensures that your computer does what it is supposed to, even if the users do what they should not do. Discretionary Access Control (DAC) is a type of access controls that provides protection to the files in a computer system. This type of control restricts access to files based on the identity of users or groups which they belong. It is discretionary and lets you tell the computer system who can have access to your files and therefore you can specify the type of access allowed. For example, you can allow anyone to read a particular file in the system, but allow only you to be able to change it. According to Whitman (2011), this type of control access is rarely used with high security systems because someone with permission to access files is able to pass that permission either directly or indirectly on to any other person. This capability poses a threat to the security of the files and can be dangerous to a high security system. An organization that requires high security, but the operating system only supports DAC, can compensate with the use of an Access Control List (ACL).

Introduction In the present world, the Access Control System is used in all the places where it is intended that a system should allow the authorized persons to get in or leave the facilities as and when required and also to keep a record about these movements. Basically it determines who is allowed to enter or exit; similarly allowed to exit or enter even with the time when they are allowed to enter or exit. In the past, the same job could have been partially done by locks and keys. But there were number of limitations of the mechanical locks & keys. Firstly, it did not provide any restriction to the key holders to specific times & dates. Secondly, it did not provide any records of the key used to a specific door. Thirdly, the keys can be easily copied or transferred to the unauthorized person. Finally, when the key is lost, the authorized person losses his access to the protected areas and the locks must be re–keyed. Electronic Access Control System has come forward to solve the problems of mechanical locks & keys. The system uses a computer network where a wide range of credentials or identifications are used to replace those mechanical keys.

It is also possible under some operating systems for the network or system administrator to dictate which permissions users are allowed to set in the ACL's of the resources. Discretionary Access Control has a more flexible environment than Mandatory Access Control, but also increases the risk that data will be made accessible to users who should not gain access. Understanding permissions about the security of file servers on the network will increase network security (Bushmiller, 2011). 2 Mandatory access control Describe how and why mandatory access control will be used.

All access to resource objects is controlled by the operating system based on setting configured by the system administrator. With MAC it is not possible for users to change the access control for any resource. Mandatory Access Control starts with security labels, which contain two types of information and are assigned to all resource objects on the system. The two types of information are classification, such as confidential or top secret and a category, which is basically an indication of the project or department to which the object is available, or an indication of the management level. ...

Its purpose is to increase security by determining who, when and where are they allowed to enter or exit. When a credential is put forward to a reader, the reader sends the credential's information to a control panel. The control panel compares the credential's information to an access control list which then accepts or denies the presented request, and sends a transaction log to a database. If there is a match between the credential and the access control list, the door is unlocked and when it is denied the door remains locked.

Inadequately secured wireless communication "Wireless security isn't just a big issue for control systems, but for all uses, mainly because wireless is becoming so pervasive," says Staggs. "It's very easy to plug wireless in almost anywhere. However, you have to be able to find the signals and know if someone has put in a rogue point. "Before installing wireless, it's important to do a complete assessment to identify the best areas for wireless use and ensure that leakage out of the plant is minimized. There will be a wireless leakage when you have transmitters or wireless–enabled workers walking around with tablet PCs or handheld devices. Those devices may be transmitting in an area outside a plant." Solution can be separation by segmenting the wireless networks from the rest of the control network.
