Application Of An Operating System Security

Application Of An Operating System Security
Abstract
This paper presents a description of an operating system security design that addresses the need for
flexibility to control dissemination of usage rights, administration of fine–grained rights, and
validates the reversal of prior access rights. The system that can handle this enormous task is the
Flux Advanced Security Kernel (Flask) microkernel–based operating system architecture, according
to research conducted by the National Security Agency (NSA) and researchers at the University of
Utah. Based on the results of testing and observations, the Flask architecture prototype is flexible to
operate and was found to be practical to apply. The Flask architecture proved capable of overcoming
most obstacles to attain policy ... Show more content on Helpwriting.net ...
There is a wide range of computing environments and products that support these environments,
with each one having distinctive security needs. Computing systems must have the flexibility to
support many diverse types of security operating systems. This is the crux of the problem that has
facilitated research into finding a system that is multi–faceted and able to provide fine–grained
controls identifying who has access to which levels of data, determine which users have permission
to information based on policies and procedures, and revoke access rights that had been established
previously. The Flask model prototype has proven to meet the needs for an operating system that
contains policy flexibility. It has a security policy server capable of making determinations about
who has access and to what extent. Moreover, the Flask security system is able to split mechanism
and policy with a fuller set of safety measures to be maintained with diminished requirements for
policy–specific modifications. "The Flask architecture cleanly separates the definition of the policy
logic from the enforcement mechanism. The security policy logic is encapsulated within a separate
component of the operating system with well–defined interfaces for obtaining security policy
decisions. This separate component is referred to as the security

Wireless Security : Wireless Network Essay
Wireless Security Overview
Wireless networks serve as the transport mechanism between devices and among devices and the
traditional wired networks (enterprise networks and the Internet). Wireless networks are many and
diverse but are frequently categorized into three groups based on their coverage range: Wireless
Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area
Network (WPAN )and etc.
WWAN includes wide coverage area technologies such as 2G cellular, Cellular Digital Packet Data
(CDPD), Global System for Mobile Communications (GSM). WLAN, representing wireless local
area networks, includes 802.11, HiperLAN, and several others. WPAN, represents wireless personal
area network technologies such as Bluetooth and IR
All of these represent potential threats in wireless networks as well. However, the more immediate
concerns for wireless communications are:
Denial of service
Malicious hackers
Theft of service (Identity theft / MAC spoofing)
In wireless security, information must be protected from unauthorized, unanticipated, or
unintentional modification. Security requirements include the following:
Authenticity–A third party must be able to verify that the content of a message has not been changed
in transit.
Nonrepudiation–The origin or the receipt of a specific message must be verifiable by a third party.
Accountability–The actions of an entity must be traceable uniquely to that entity.

Samba specifically supports Linux access to print services for Windows alongside CUPS and file
services as well as authentication through a daemon called Winbind. Winbind, provides
communication for Pluggable Authentication Modules (PAM) and Name Server Switch (NSS) on
the Linux side with Active Directory on a Domain Controller. It uses Kerberos and Lightweight
Directory Access Protocol (LDAP) to authenticate and retrieve user and group information.
(Kirkpatrick, 2008) Printing capabilities from the Linux systems will be essential and will most
likely be very similar to the requirements with the user tasks in the current XP configuration. Since
the print services are managed by Windows resources, meeting the printing needs of the Linux users
will be accomplished through SMB using Samba. The printers currently active on the network have
been verified to work with Linux systems, so once properly configured, Linux users will have no
problem with their printing needs. The protocol for Samba is already integrated into the Windows
Server environment so configuring the settings on both the Linux and Windows sides is not a
complicated process, although it is an additional requirement that would not be required for a
Windows client workstation. (Shinder, 2012) The information required to configure Linux systems
to print in the existing environment consist of the print server, printer share and appropriate
Windows login password. A script using smbclient shell will support the setup for printer
configuration. File sharing in a structured environment is a useful feature that is common in a
Windows environment and provides ease of access based on permissions established for designated
file shares. Fortunately, this capability is not restricted with the integration of Linux. Samba is a
versatile package that can serve as the solution for many areas to include file

Evaluation Of A Central Security Management System Essay
4.1.3 ENDPOINT ATTACK RESPONSE
When an endpoint is attacked, it should defend itself, report the attack and reconfigure itself to
thwart the attack based on policy. The responsible security management should provide the policy to
the secure agent in the endpoint in response to the attack, or a priori for use when communication
with the server is severed.
4.1.4 REMOTE POLICY MANAGEMENT
A central security management system defines the configuration of the security controls and
functions as a form of a security policy for each endpoint. The security policy is communicated to
the secure agent that authenticates and enforces the policy at the endpoint. Policies can be modified
and updated to the security agent on–demand to address new vulnerabilities or changing concerns in
response to changing circumstances.
4.1.5 LOGGING AND EVENT MONITORING
The security agent must be able to monitor and record events as they occur at the endpoint including
events pertinent to security violation, user login/logout, data access, configuration update,
application execution and communication.
4.1.6 APPLICATION WHITELISTING
Mechanisms should be in place at the endpoint to ensure that only known and authorized application
code (whitelist) including binaries, scripts, libraries are allowed to execute on the endpoint to
prevent the endpoint from being compromised by malicious code. All other execution attempts
should be halted, logged and reported. The security management system may update the

Designing A Scalable Workload Management System
2.4.1 Neutron Overview
Without including any network–specific functionality, it would be possible to develop a scalable
workload management system. While the connectivity between compute nodes is required and also
for the external access, it is important to have network–specific functionality, but it would be
possible to benefit from the existing networking infrastructure to allocate IP addresses and relay data
between nodes. However, the main problem with such an approach is the network management
system would not be able to separate traffic between users securely and efficiently when there will
be a multitenant environment[13]. Neutron is a part of OpenStack project focused on delivering

A simple model of virtual network, subnet, and port abstractions to define network resources are the
base for creating OpenStack Networking component. Similar to a VLAN in the physical networking
world, network in OpenStack is an isolated layer–2 segment. Subnet is a block of IP version 4 or
version 6 addresses, set as an address pool from which OpenStack can assign IP addresses to virtual
machines (VMs). Each subnet is stated as a Classless Inter–Domain Routing range[13].
2.4.2 Neutron Architecture
The main process of the openstack networking component is neutron–server, which transmit user
requests from OpenStack Networking API to the configured plug–in. There are three agents that
interact with the main neutron process though the message queue or the OpenStack Networking
API[9]:
– Neutron–dhcp–agent: The main function of this agent is to provide Dynamic Host Configuration
Protocol (DHCP) service to all tenant networks[9].
– Neutron–l3–agent: The main function of this agent is to translate and forward Layer3/Networking
address to enable external network access for VMs on the tenant networks[9].
– Neutron–*–agent: This is an optional plug–in agent, which is responsible of performing local
virtual switch configuration on each hypervisor[9].
When Nova launches a VM instance, the service communicates with OpenStack Networking in
order to plug each virtual network interface into a particular port.

Another feature that "Ubuntu" offers is the ease of authentication. Authentication plays an important
part as it helps computers on a network to recognise each another and allows for information to be

ensures that a shared directory service can be built if it is needed.
Supported versions of Ubuntu Server come with "Likewise–Open". This is used to integrate with the
system using Microsoft Active Directory. Machines on Active Directory can be identified, share
credentials and access resources with "Ubuntu" machines through the use of this software.

Operating System Security Concerns : Os
Operating System Security Concerns
The OS in general lacks security and portability. The services on an OS are acutely vulnerable to
malicious and random faults, as the OS are huge and are prone to security and reliabilities gaps.
Moreover, the modification of the state of an OS is extremely complex in nature. Additionally,
changes like cloning, encrypting, moving, or restoring are too challenging to accomplish. The OS
provides the capabilities of event logging, however, this ability has a few shortcomings, such as, the
intruder can disable the logging mechanisms before the attack, and secondly, it is often extremely
difficult to find the critical information necessary to discern the attack and steps employed by the
intruder to harm the OS, therefore, the overall recovery process becomes problematic (Chen &
Noble, 2001).
Furthermore, in the contemporary OS, the expectations of multi–tasking, time–sharing, and
resource–sharing are abundant. The fundamental OS contains the security features such as task
control blocks, virtual memory spaces, and inter–process communication. The OS also contains
restrictions on operations and processes based on user identity and ownership level. However, the
OS security lacks various integral considerations, for instance, restrictions based on the
trustworthiness and operations of the utilities, user roles, and the data integrity and sensitivity.
Therefore, the OS can be compromised effortlessly by an attacker by means of a security breach in

Security Issues For Cloud Services Essay
As depicted in figure 3, the technical details, arrangements and management of the cloud service
providers' network is transparent to the cloud user. From the end of the cloud user, the service from
the provider comes in the form of SaaS, PaaS or IaaS where the cloud user has no intention or worry
about what goes on in the internal arrangement of the cloud service providers' network. Any
disruption of any form for whatever is the reason, deem to the cloud users either as service
unavailability or quality deterioration – its affect and ways to counter this disruption is a critical part
for the cloud infrastructure. Security issues might play a stimulating role as a driving factor for any
aforementioned disruption. IV. AUTHENTICATION IN CLOUD Security is the most prioritized
aspect for any form of computing, making it an obvious expectation that security issues are crucial
for cloud environment as well. As the cloud computing approach could be associated with having
users' sensitive data stored both at clients' end as well as in cloud servers, identity management and
authentication are very crucial in cloud computing. Verification of eligible users' credentials and
protecting such credentials are part of main security issues in the cloud – violation in these areas
could lead to undetected security breach at least to some extent for some period. A possible
authentication scenario for a cloud infrastructure is illustrated in figure 4. Figure 4: Authentication

Bring Your Own Device ( Byod )
Bring Your Own Device (BYOD) is referred to it by many names: bring your own danger, bring

commonplace in all sectors across the world. What used to be unthinkable, using one's own personal
mobile device or smartphone for work is now emerging as one of the biggest technology trends of
this decade. The idea of using a personal device at work developed when many executives got their

The issue is two–fold, one being that IT departments have lost the ability to fully manage devices
that connect to the company's network, but also employees are now demanding that they have the
ability to conduct company business and have access to extremely secure company resources from
multiple personal devices. Obviously this hasn't gone over very well from the IT perspective.
Initially IT departments were very resistant to change taking into consideration the huge security
risk allowing these devices onto the network presents, however more and more departments are
beginning to adopt these new practices, but at the same time are still very hesitant because they
remained very concerned about the inherent risks of permitting personal devices to access and store
sensitive corporate data. The timeline outlined below gives an excellent graphical representation of
where BYOD started in the early 200's and where it is and going now that it's in its third wave and
really finding its way as a mature solution in the enterprise. Mobile devices are a mixed blessing for
enterprises. CRN reported on a Poneman Institute, a IT security research firm, found that 77 percent
of corporate professionals who responded to the survey said that the use of mobile devices in the
workplace is important to achieving business objectives, but almost the same percentage, 76 percent,

Review Of Tools Of The Trade
Review of Tools of the Trade For a smooth and efficient functioning of the organization's
Information Systems (IS), the hardware management tools play a vital role. Although plentiful
hardware management tools and resources are necessary for the trustworthy operation of an
Information Technology (IT) infrastructure, however, the tools specifically to manage a firewall and
scan a network, and the universally reliable knowledge bases are the three decisive requisites

In the modern and dynamic organizations the management of these firewall rules and policies
become extremely cumbersome and complex. As a result, the security problems may creep in, and
may create havoc on the security and performance of the organizations' IS components. An efficient
firewall management tool like SecureTrack is a viable solution in these strikingly critical situations,
which can help clean up the rules and policies, improve the performance of the firewalls, and
eliminate any security leakage (Sohoni, 2010). Tufin (2015) in the documentation of SecureTrack
Orchestration SuiteTM, provided the extensive list of features and benefits that an organization will
attain by chosing SecureTrack as the firewall management solution. The foremost benefit is to
provide the managers a comprehensive user interface control to manage rules across both public and
private cloud as well as the firewalls connected to the network. Further, it automates the firewall
change process, therefore, strengthens the regulatory compliance with government and industry
standards, and security process. It helps to mitigate the cyber threats by optimizing the policies
related to security. Moreover, it minimizes the downtime of the network and the deployed
applications, and provides the immensely vital factor of continuity to the business (Tufin, 2015).

Research Paper On Amoeba
 Introduction
Distributed Operating System
A distributed operating system is one that looks like an ordinary centralized operating system but
runs on multiple, independent central processing units (CPUs). It implements transparency i.e. use
of multiple processors is invisible to the user. The users of a true distributed system are not
concerned with which machine (or machines) their programs are running on, where their files are
stored, and so on. It is the software, not the hardware, that determines whether a system is
distributed or not. A high degree of fault tolerance is an implicit goal for such a system.
What is Amoeba?
Amoeba is a general–purpose distributed operating system. It began as a research project at Vrije
Universiteit (Free ... Show more content on Helpwriting.net ...
Every machine running Amoeba runs the same microkernel. The kernel supports the basic process,
communication, and object primitives, communication, I/O and memory management. Everything
else is built on top of these fundamentals, usually by user–space server processes. Processes
(Definition, Creation and Their Scheduling):
–What is a Process
A process in Amoeba is a running program, which has an address space, a set of registers and a
stack. Processes are distributed over multiple computers. At any given time, a computer may have
any number of processes running on it, with each process possibly having multiple threads. Amoeba
does not, however, have threads of a common process running on multiple computers.
–Process Creation
Forking is slow and inefficient under Amoeba. This is because when a new process is started it will
usually be started on a different processor from the parent process. The idea of copying the text of a
totally irrelevant program to another processor is inefficient in the context of a distributed system.
Therefore there is a routine called newproc which can be used to start a new process more efficiently
than with fork and exec.

Benefits Associated With A Cloud Based Enterprise Resource...
Executive Summary As a medium sized company who wishes to enhance their e–business presence
by incorporating an online Business–to–Consumer (B2C) model that sell its products directly to the
consumer (Baltzan, pp. 207, 2015) and aligning the right information systems and technology to
their overall business strategy is vital to their success. The business plan recommended by the
company is to implement a cloud–based Enterprise Resource Planning (ERP) solution that supports
and enhances their current information systems and technology (IS&T) requirements. By
outsourcing the IS&T to a web–based company, it will greatly reduce the associated costs and
simplify the implementation than the creation of a local system. Some of the benefits associated
with a cloud–based ERP are the following areas: Customer relationship management, Human
Resources, project management, finance and accounting, sales and marketing, business intelligence,
workforce management, and reporting. Another important aspect revolving around this type of
solution is that the cloud–based ERP will be tasked with the creation, implementation, and
maintenance of the company's website and customer portal. The website will be the primary
customer relationship management portal, wherein customers are able to research the company,
obtain support, view merchandise, and make purchases. Since customer relationship management
module is sales–focused, the sales and marketing team will be able to utilize the

Installing Multiple Services On A Single Red Hat...
1. Goal This lab included installing multiple services on a single Red Hat Enterprise Linux 7 Server
box, which included DNS, DHCP, openLDAP, NTP, and rsyslog. I have familiarity with installing
and managing DNS, DHCP, and NTP, while just learning about openLDAP and ryslog, which are a
new concept to me. The installation and configuration of openLDAP allowed me to get a basic
general look at the operation of openLDAP, without going too in–depth. I was able to learn how to
correctly and efficiently configure both the openLDAP server and client, add users, install schemas,
and modify configuration files. Rsyslog was also a new concept to me which brought be a greater
sense of local logging using Red Hat Enterprise Linux 7. This lab focused on deploying a DNS
server, a NTP server, and a DHCP server to handle things such as IP address pools, hostname
resolution, and a systematic time sync to keep all of the nodes on the network on the same page.
Rsyslog allows us to remotely access log files from our servers, allowing us to determine issues
from a node without actually being on that node, which is good when dealing with a client computer
that is having issues. OpenLDAP allows us to create a directory in a similar manner as Windows
Active Directory, to store information in an easily accessible lightweight database.

Protocol (LDAP), is an application convention for perusing and altering registries over an IP system
(Michelle Christian, 2007). It is a standard innovation for system registries. Michelle Christian
(2007) declared that Network catalos are particular databases that store data about gadgets,
applications, individuals and different parts of a PC system. It is not restricted to contact data or data
about individuals. It is fitting for any sort of index like data where quick lookups and less successive
redesigns exist. Donnelly (2008) uncovered that LDAP was made in 1995 as a scholastic college
task, and afterward popularized by Netscape in the late 1990 's. It is discovering much
acknowledgment due to its status as an Internet standard. It can likewise be tweaked to store any
kind of content or twofold information. Note that it is not a registry yet a convention. Donnelly
(2008) further clarified that LDAP arranges data in a various levelled way utilizing indexes. These
indexes can store an assortment of data and can even be utilized like a System Information Service
(NIS). NIS empowers anybody to get to their record from any machine on the LDAP empowered
system. Much of the time, LDAP can be utilized additionally, as a virtual telephone index,

This process is accomplished by checks made prior to the ObjectInputStream.resolveClass call. If

Although, this is a feasible solution, it can be an expensive one to implement because of the amount
of extra functionality that comes with the Burp Extender. It is also not supported across all servers
and containers and therefore may not be feasible. (Portswigger, 2016)
The biggest problem is the knowledge of the attack port and domain that the system is running on. If
these were changed and access is restricted, it would make it much more difficult for the attacker to
exploit a system. A random port should therefore be assigned per domain and access to the servers
restricted to only specific IP addresses which can be put on a whitelist. Embedded LDAP directories
can be put into place that allows only specified users access to the server's console and settings.
However, an external LDAP directory is recommended as the embedded one can still be
compromised. A Splunk report describing any changes to these directories should therefore be setup.

Review and Assessment
Security improvement is an ongoing process not a goal. New avenues for attack are being found
rapidly, and the United States Computer Emergency Response Team (US–CERT) is one
organization that tracks an announces them. The magnitude of security vulnerabilities can be
staggering. US–CERT announced 36 high, 56 medium severity, and 18 low severity attacks
discovered in the week of March 3rd alone (2014).
Maintaining a continual security posture is critical to staying ahead of the vulnerabilities. With the
number of new attacks constantly on the rise even the most seasoned IT security staff can overlook a
vulnerability. To assist your staff in reviewing the security of your infrastructure a vulnerability
assessment is a valuable tool. There are many free and licenses software packages such as Nessus
and Metasploit which can be loaded onto a workstation and left to run. These packages run through
a library of known vectors of attack against your network equipment and servers. You are then
presented a report showing a list of attack successes and suggested mitigation steps. Such software
should be run on a monthly, or even weekly, basis by your internal staff against your critical
infrastructure.

Essay On Active Directory
First, what is Active Directory? Active Directory (AD) is a database management system created by
Microsoft. It is also known as Microsoft's network operating system (NOS). A network operating
system can be simplified as a networked environment for various types of resources stored in a
central system that is managed by administrators and also accessible for end users. Active Directory
takes different information about network components and stores it. This allows active directory's
clients to find objects within its namespace. Namespace or Console trees, refers to an area where a
network component can be located. For example, within the table of contents of a book creates a
namespace where chapters can be settled into page numbers. For ... Show more content on

The primary use for the original LDAP was a gateway between X.500 servers. Clients would
interface with the LDAP and that would translate the requests and submit them to the server
(Northrup, 1999). The group at University of Michigan wanted to remove the gateway to develop a
directory server enabled by LDAP. To do this the LDAP would provide most of the functionality
needed to as many clients as it can. Overall, this removed all the unnecessary features that were
implemented and kept the concepts of the X.500. In 1995 the first LDAP directory server was
released. The last major update to the LDAP was in 1997. This version, LDAPv3, provided many
features and made LDAP stronger and expandable enough so that many vendors and clients can
implement it easier (Northrup, 1999). Since this version, many different companies have taken the
ideas and developed their own type of Directory Servers. For example, the Windows 2000 server.
Windows 2000 is an operating system released to retail in February 2000. Active Directory was
introduced to replace the Windows NT's domain model they had previously. With Active Directory
in place, it gave administrators a different way to manage policies and accounts. Administrators can
also place programs and updates with a notably greater scalability compared to previous Windows
versions. The services could be installed on the actual Windows 2000 server, the Advanced Server,
and/or the Datacenter Server. The Active Directory

Active Directory is a directory service that Microsoft developed for Windows domain networks and
is included in most Windows Server operating systems as a set of processes and services. An Active
Directory domain controller authenticates and allows all users and computers in a Windows domain
type network– assigning and enforcing security policies for all computers and installing or updating
software. When a user logs into a computer that is part of a Windows domain, Active Directory
checks the submitted password and determines whether the user is a system administrator or normal
user. Active Directory makes use of Lightweight Directory Access Protocol (LDAP) versions 2 and
3, Microsoft's ... Show more content on Helpwriting.net ...
An object is uniquely identified by its name and has a set of attributes–the characteristics and
information that the object represents– defined by a schema, which also determines the kinds of
objects that can be stored in Active Directory. The Active Directory framework that holds the
objects can be viewed at a number of levels. The forest, tree, and domain are the logical divisions in
an Active Directory network. Within a deployment, objects are grouped into domains. The objects
for a single domain are stored in a single database (which can be replicated). Domains are identified
by their DNS name structure, the namespace. A domain is defined as a logical group of network
objects (computers, users, devices) that share the same active directory database. A tree is a
collection of one or more domains and domain trees in a contiguous namespace, linked in a
transitive trust hierarchy. At the top of the structure is the forest. A forest is a collection of trees that
share a common global catalog, directory schema, logical structure, and directory configuration. The
forest represents the security boundary within which users, computers, groups, and other objects are
accessible. The objects held within a domain can be grouped into Organizational Units (OUs). OUs
can provide hierarchy to a domain, ease its administration, and can resemble the organization's
structure in managerial or geographical terms. OUs can contain other
