Challenges Faced By Computer Network Security

Challenges Faced By Computer Network Security
Abstract– The rapid development in computer network technology leads to the security challenges
faced by it at every step of its growth. Three main threats facing computer network security include:
hackers, computer virus and denial of service attack. Safety factors of the network are mainly:
resources sharing, data communication, computer virus and TCP/IP protocol security flaws. A safety
network system should include at least three kinds of measures: legal measures, technical measures
and review and management measures. The paper analyzes the main threat facing computer network
security, discusses network security technology and advances some effective countermeasures in
view of the hidden danger of current common network security. ... Show more content on

Different users have different understanding towards network security. To general users who may
just prefer individual privacy or confidential information to be secure and to be protected from
eavesdropping, tampering and forge. But for network providers, they not only care about the
network information safety, but also cope up with sudden disasters, such as military strike to
network hardware damage. Major threats of computer network 1. Damage the integrity of
information: attackers may damage the information integrity in different aspects: changing the order
and form of information. Deleting the information and inserting some other content. 2. Pretending:
The attacker may pretend to do the following: pretend to be leadership issue orders and read the
documents; Pretend to be host deceives legitimate hosts and legitimate users. Pretend to be network
control program to show or modify the access to key information, passwords, etc, excessive use of
network equipment and resources: take over a legitimate user, cheat the system, take up the
resources of the legitimate users. 3. Destroy System Availability: The attacker may damage from the

Kerberos Essay
Kerberos and Firewalls
Kerberos
Kerberos is defined as an authentication protocol combined with a suite used in implementing the
software (Nicola & Aargau). The authentication protocol has its name derived from the three–
headed dog in the Greek mythology used for guarding the entrance to the underworld. The protocol
involves three entities; the first two are aimed at authenticating one another i.e. the resource center
and user while the third party acts as the key distribution center or the mediator between the two
keys.
Kerberos authentication protocol is based on symmetric key cryptography where the key used for
encryption and decryption is the same. The formula for the protocol is
DK (E K(M)) = M
Where D stands for decryption, K stands for the key, E stands for encryption, M stands for
encrypted text. In case the key is the same for both encryption and decryption procedures, the
decryption process leads to the same plain text as the original text before encryption.
The key distribution center comprises of two components, integrated into one server. These
components are the authentication server and the ticket–granting server. Considering three entities,
that is, the resource center, client and user Z, the request and authentication process works in the
following way. The user Z feeds in a username and password into the client machine, which is
encrypted to form a secret key. The user Z through the client then contacts the authentication server,
which in turn sends the

How Does Network Security Work?
Target, Sony, and At&t besides being worldwide business entities what common denominator do all
three of these companies have? That's right, a recent security breach. Some of these data breaches
allowed access to thousands of individuals debit card and social security numbers. Others have
given access for people to manipulate the networks for their own personal or financial gain. Cyber–
attacks are not just limited to department stores, or even banks. Cyber–attacks can happen
essentially to any entity with an informational data base. Businesses now are trying to discover new
ways to protect their network infrastructures.
How Does it Work?
First and foremost it is most important to explain how network security works. There are three
general types of security controls. These consist of administrative, physical, and technical controls.
Administrative controls pertain to how your business has compiled security agreements and how
new technology implementation should occur. Physical security, is exactly what it sounds like,
physical aspects. This might include locks on doors where servers are located, fences around
facilities where important information is stored or any other control measure that would physically
delay an attacker from being able to reach a network. Technical controls consist of what an IT staff
implements within the network to decrease the risk of a breach. Examples of this include encryption,
configurations, and layered security. It takes a combination of all

Network And Computer Systems Become Universal And Exposed,...
INTRODUCTION As networks and computer systems become universal and exposed, security
threats and risks continue to grow more rapidly. This causes enormous threats; therefore, Security
specialists and experts are continuously trying to find solutions for these kinds of threats through
different methods like attack signatures and looking for methods to prevent them. Nevertheless, as
solutions are formed, new types of threats emerge, for example spam mails, spywares, worms and
Trojans just to mention a few.
A growing program problem in our technologically advanced society is the increase in security
related issues for small to medium industries (infosec reading room, n.d.).The digital age has also
appeared with a variation of benefits to organization such as Just Love and individuals. Information
technologies are becoming more broadly used every day. As networks and computer systems
become more pervasive, security threats and risks continue to grow more rapidly, therefore
transferring data from paper and pen environments to computer systems does not always happen.
Increasing complication and sophistication of the ever–growing information technologies has
prompted unique and unparalleled challenges for organizations such as mine to protect their
information assets. The Internet is such a marvel that an organization today cannot operate without
it, but on the other hand too, living with the Internet also opens the organization to threats like
viruses, hackers and internet fraud

Security Assessment and Recommendation
Running head: POTENTIAL WEAKNESSES Security Assessment and Recommendations Security
Assessment and Recommendations I have been charged with the task of identifying potential
security weaknesses and recommending solutions for Quality Web Design (QWD). The project was
completed in two phases. The first phase of the project specifically identified and defined two
potential security weaknesses: software and policy. The second phase recommends solutions to these
potential weaknesses. I chose a scenario that outlines specifics of the organization's type of business,
business processes, assets, services, and security controls. It is crucial for any organization to take
necessary steps in securing their business' assets, and customer's ... Show more content on

An attack to these mission–critical processes can mean a decrease in the organization's revenue;
client's personal information being accessed, modified, or even deleted; and even degraded network
performance. QWD would lose significant clientele and would not be as appealing to their target
audience – not so good for their mission of providing top quality services. Policy Reducing the
exposure of the corporate network from outside attacks is crucial in protecting mission–critical
processes for QWD. The security assessment doesn't end with software firewalls for their remote
users. The company's security policy must also address this vulnerability. QWD has policy in place
that speaks to who has access to data and the type of data; username standards; password length,
complexity, rotation, and history; and security training. However, their policy doesn't address remote
access devices: installation and configuration of firewall and anti–virus software on all employees'
remote computers and acceptable use. These are critical in preventing remote computers and mobile
devices from compromising the corporate network (Ruskwig, 2006, pp. 1). Without such a policy in
place, there is no guideline for securing QWD's assets. Any remote employee that has Internet
connection that is always on runs the risk of infection or even allowing access to

Computer Security : Computers And Networks
Accessing other user's files: Users may not alter or copy a file belonging to another User without
first obtaining permission from the owner of the file. Ability to read, alter, or copy a file belonging
to another User does not imply permission to read, after, or copy that file. Users may not use the
computer system to "snoop" or pry into the affairs of other users by unnecessarily reviewing their
files and e–mail.
Accessing other computers and networks: A User's ability to connect to other computer systems
through the network or by a modem does not imply a right to connect to those systems or to make
use of those systems unless specifically authorized by the operators of those systems.
Computer security: Each User is responsible for ensuring that use of outside computers and
networks, such as the Internet, does not compromise the security of CyberTech's Computer
Resources. This duty includes taking reasonable precautions to prevent intruders from accessing the
company's network without authorization and to prevent introduction and spread of viruses.
Viruses
Virus detection: Viruses can cause substantial damage to computer systems. Each User is
responsible for taking reasonable precautions to ensure he or she does not introduce viruses into
CyberTech's network.
Users should make sure that virus detection software is loaded on their computers and that it is
turned on at all times. All material received on floppy disk or other magnetic or optical medium and
all material

Network Security : A Secure Platform For Computers
Networking security the process of taking physical and software preemptive evaluations to protect
the underlying network foundation from unauthorized admittance, misuse, glitch, modification,
demolish, imprudent revelation, thereby creating a secure platform for computers, users and
programs to implement their permitted critical functions within a secure environment. Network
security has become significant due to the patent that can be obtained through the Internet. There are
essentially two different networks, data networks and synchronous network composed of switches.
The Internet is considered to be a data network. Since the prevailing data network resides in
computer based routers, information can be accessed by special programs, such ... Show more

Confidentiality prevents the access of the unauthorized system and person to the sensitive
information of an organization. Due to the increasing contentious and competitive business
environment, confidentiality is very important for an organization. The failure in protection of
confidentiality of a business can cause serious issues if the confidential information gets into the
wrong hands, they can use this information for illegal activities such as scam, fraud and stealing
money which can result in loss of productivity. Integrity is information that cannot be changed
slightly and has to be reliable. Although millions of dollars have been invested in this sector, but still
the information in the warehouses is inaccurate and sometimes incompatible with its origin. As the
result the data warehouse faces failure, low acceptance and confidence of the clients and users.
Incorrect and incomplete information decrease the operational ability; become the cause of incorrect
business decisions. Availability means, the required data and information must be available and
accessible to the authorized personals at anytime and anywhere. For example, the information is in
the server, but the server is overloaded and not working properly or the server crash and no one able
to access the information needed. It is important to understand that the information unavailable not
only in case when it is destroyed or lost, but also

A Brief Note On Companies And The Largest Ever Consumer...
Case Study #2: Maxxed Out: TJX Companies and the Largest–Ever Consumer Data Breach
There are five components to the operations security process that companies use to analyze. These
five modules provide a company a full analysis of the risks, vulnerabilities, and threats of their data
and how to mitigate them. This process identifies all the critical information the company or
organization have such a credit card information like TJX had on their main server. Identifying this
information is crucial so the business knows what valuable assets, or data is being stored. If a
company does not recognize this material, the material is unprotected.

Also, TJX did not apply counter measures in place of those defined vulnerabilities or threats which
costed the company huge losses. If the company implemented the WPA security protocol, the risks
could have been small.
There are multiple methods to improve the security at TJX to prevent future breaches. The network
wireless system should be upgraded to Wi–Fi Protected Access 2, WPA2, from WEP. WPA2
provides the most secure protocol that is available on a wireless network. WPA2 uses Advanced
Encryption Standard to encrypt all the data when the data is in motion. AES encryption takes a
hacker months, even years to break. If the company wants customers to have free Wi–Fi then have
two separate networks in which one is has a network password and other just requires a login with
terms and conditions.
For the wired/wireless connections, TJX can institute a virtual private network, or VPN, to connect
with the servers that have sensitive information. This allows the connection between the servers and
device to be secure but the data is not. VPN does have limitation such as devices, but is an
alternative to WPA2 and better than WEP. VPN is ideal for documents such as sales reports,
inventory, and strategies. TJX must implement these standards on all of the retail locations to
safeguard all the data being processed throughout the business day.

Impact Of Technology On The Security System
T.J.X. was the leading fashionable brand name, off–price product retailer in the U.S. In 2013 the
company's net sales reached $27 billion, increased by 6% compared to the same period in 2012. In
2007, the company was revealed by the investigating authorities that their database had been
penetrated by hackers for 1.5 years, and been causing 94 million debit/credit card and customers'
personal information stolen around the world of its 2,500 branch stores.
In 2005, the discussion of upgrading the wireless system to the standard WAP was raised in the
information department. However, they choose to focus more on constraining the budget rather than
to invest on wireless security system. According to the corresponding email between the CIO and
the employee, they were aware the necessity of upgrading the system, but decided to overlook on
the potential risk and the contingency plan they relied on was hope, hoping that they will not get
compromised. And it was the same year when the first major intrusion into the company's system
had occurred at Marshalls. The criminal hacked into the network and established connection with
the main TJX server, then downloaded card information with their program installed onto the server.
Since the hackers had access to the main database, they were able to modify and delete log files and
to move data to hide their movements. This could be one of the reasons why it took the company
almost two years to detect that there was some suspicious software

Computer networking was invented to make the computers communicate with each other.
Communication between computers is faster and easier than any other mode of communication. In
addition to providing faster communication, computer networking empowered the computer users to
to access remote programs and databases. Apart from these plus points, there are several other
benefits of computer networks. Computer networking reduces the business process expenditure by
making hardware and software resources remotely accessible and by downsizing to microcomputer–
based networks instead of using mainframes. Accumulating data from multiple resources has
become effortless process, which also ensures the reliability of the information.
Definition Of Computer Network
A computer network is defined as an interconnected system in which computers are interlinked to
each other for communication purpose so that resources and information could be accessed by all
connected nodes.

Have you ever surfed the web and received a popup alerting you a threat is detected? If so, you are
not alone. This is a very common issue web browsers and organizations face. In order to resolve or
prevent such issues, it is key to learn about the security of your network. Network security is the
protection of networks that help secure files and directories of a computer. It helps protect the user
from hackers, virus attacks, misuse and prevents unauthorized access. The importance of learning
and becoming aware of network security is important for protecting yourself and others around you.
I will be discussing the common type of attacks, methods to protect your computer from harm and
discuss what the future may hold for network security.
There are many attacks that can be associated with network security, eavesdropping,
viruses/malware and Trojans, phishing, IP spoofing attack and lastly denial of service.
Eavesdropping, has two subcategories passive and active. Passive eavesdropping refers to someone
listening to a phone call, or reading a chat email (Daya, Bhavya). Active eavesdropping refers to the
hacker physically going in and distressing the conversation (Daya, Bhavya). This type of attack
allows the hacker to steal confidential information. In this circumstance, it is important to have some
sort of network security because having someone listening in on a personal conversation can be
detrimental. This can be solved

Best Practices For Network Security
Best Practices for Network Security Network security, in this technological age, should be one of
the most important items of concern for any business owner or network administrator. Since just
about every company out there is connected to and conducts some sort of business over the Internet,
just about every one of them is at risk from outside threats. This means that they should take certain
steps in order for them for them to conduct their business securely. Beyond the initial steps, it must
be known that there is no end to network security as it is a process that is continuous. The goal of
this paper is to discuss some "best practices" that companies should follow in order to provide
adequate protection.
Recent examples In recent years, there have been a number of big name companies that have fallen
victim to security breaches. In 2011, Sony's PlayStation Network suffered a massive breach and as a
result some 77 million user's accounts, containing names, addresses, e–mail addresses, birth dates,
usernames, passwords, and possibly credit card numbers, were compromised (Baker & Finkle,
2011). Another, more recent, breach took place earlier this year. JP Morgan Chase had a similar
breach this summer in which over 76 million retail clients and over 7 million business clients saw
their personal information compromised (Avoyan, 2014). While there was no evidence of account
numbers or other financial data being compromised, the mere fact that a bank this size could be

The Aftermath Of The 2008 Financial Crisis
In the aftermath of the 2008 financial crisis, Congress recognized the need to regulate nonbank
institutions. Many of the financially distressed institutions were not regulated by the same standards
bank holdings were. As a result The Financial Stability Oversight Committee was created under
Title I of the Dobb–Frank Wall Street Reform and Consumer Protection Act. The committee was
signed into law by Barack Obama on July 21, 2010 and serves three primary purposes. One is to
authorize and determine nonbank financial institutions that if under material financial distress or
failure, can threaten the financial stability of the United States. The designated institutions are
referred to as systematically important financial institutions (SIFIs) and are subject to the regulation
and supervision of the Federal Reserve System (Board of Governors). Another purpose of the
committee is to promote market discipline and eliminate the expectation of companies stakeholder's
relying on the U.S. government bailout as safeguard from failure or loss. Last but not least the
committee is also expected to recommend standards and safeguards for U.S. and global financial
systems. In the executive summary of the 2014/15 annual reports, the committee continues focusing
on three areas of financial risk: cyber security, foreign markets and the housing finance reform.

Basic Home Computer Network and Computer Network Security...
Introduction Generally, computer network security systems and structures considered robust are
preceded not by software and hardware but by careful planning. A typical computer network
security plan must take into consideration a wide range of security risks and vulnerabilities and from
that, develop a road map to reduce such exposure. Given the need to protect the integrity and
confidentiality of data as well as other system quality attributes, the need to mitigate exposure
cannot be overstated.
Security Risks
In regard to security risks, key considerations include what I should be protected against and some
of the main vulnerabilities common in home networks.
Vulnerabilities
Basically, home network vulnerability can be taken to be a network weak spot that can be utilized by
security threats. According to Gervasi (2005), "home network is exposed to various cyber attacks
through the Internet, and has security vulnerability such as hacking, malignancy code, worm and
virus, DoS (Denial of Service) attack, communication network tapping..." Other vulnerabilities
include but are not limited to insecure network architecture and design as well as flaws in password
management. There are various ways of identifying and getting rid of vulnerabilities in home
networks. These include the utilization of tools designed to carry out vulnerability scans and
carrying out an audit of possible risks.
What to be Protected Against
Today, given the fact that electronic connectivity has

The Steps Of Good Computer Security Operations
Introduction
A successful BC/DR plan has defined steps within the project that must be defined. We need to
initiate the project, identify key business processes, conduct an impact analysis, develop business
continuity strategies, identify communication needs, and finally monitor and review the plan.
Mitigating the impact of a disaster be keeping mission critical capability available when needed is
key to any BC/DR plan. These plans are often critical to a company and the company 's business
model. There is a significant amount of time, money, and physical resources that go in to a
successful BC/DR plan.
Background and Significance
The steps we take to create a BC/DR resemble the steps of good computer security operations.
Threat evaluation, risk assessment, mitigation, and service priorities, are a few of the computer
security operations that directly relate to a good BC/DR plan. When implementing a BC/DR from a
administrative standpoint we see a significant shift in focus from computer security to physical
infrastructure, backup and restoration procedure, staffing, logistical operations, and connectivity. To
ensure the system stays operational in a degraded state a business must address the integrity of the
system. Without computer security considerations a BC/DR plan can fail and turn into an
unmanageable situation. During a restoration of workstation in a BC/DR plan, it may be possible to
get bad data from a location that was not maintained correctly, which could

Abstract
With the increase in the usage of the internet in recent time, cases of security breaches, threats and
malware etc. have also increased. One of the major issues in using the internet is getting the system
infected with malware downloaded from the internet. The malicious programs could be threat at
different levels i.e. from displaying a simple message to making a huge system useless. There are
various types of malware such as virus, Trojan horses, worms, spyware and adware, etc. Sometimes,
internet route is used to infect systems with these malicious programs by embedding malware with
useful programs, emailing malicious programs and various other ways to infect system through the
internet.

Threat to internet security is one of the main challenges which internet users face during electronic
transactions. This is a tree branch of computer security which also includes browser security, and
network security. The internet security's main objective is to take measures for restricting or
controlling various attacks. An insecure channel for transferring information leads to various types
of frauds and intrusion such as virus, phishing, Trojan horses, worms, boot sector viruses adware
and spyware. Various types of anti– malware and technologies are used for securing the internet. For
example, PGP and MIME technologies are used for email security, SSL and TLC are used for web
traffic security and IP Sec is used for network layer security.
A firewall is another access technology, which is used for controlling access between different
networks. Firewall sets a barrier in between the organization's network and an outside network for
restricting the illegal access to organization confidential information resources. "Firewalls can be an
effective means of protecting a local system or network of systems from network–based security
threats while at the same time affording access to the outside world via wide area networks and the
Internet." (Firewalls). This is one of the best technologies for screening network traffic and blocks
the traffic, which is dangerous for the system.

How A Network Can Be Attacked
Are We Safe! How a network can be attacked Types of attacks There are numerous types of attacks,
some of these are: Virus A virus is a software program that is designed to replicate between
computers and affect the operation of the computer. A computer virus is similar to a human virus. A
virus is a software program that is able to corrupt and delete data from the computer. The virus can
be transferred from one pc to another through an email as an attachment. Trojans A Trojan horse is a
program or utility that looks as though it would be useful and safe to use but actually it is carrying
out tasks which give others access to your computer. Trojans are usually found built in to another
program so that it is not easily discovered. The Trojan will then run when the program that it is built
into is running. Trojans are not easily discovered by antivirus software because they are written in to
the code of another program. Worms A worm is another way how a network can be attacked, worms
are very easy to spread between computers. Worms are transferred from one computer to another
without human interaction. The worms can be transferred by emails, USB drives or downloading
files. This means that worms have the capability to transfer from one computer to another and to
replicate so they can infect vast amounts of computers. Adware Another way that a network can be
attacked is Adware. Adware is a piece of software which generate advertisements (pop–ups, banners

The Core Layers Of Defense
Internet of Things is a new technology that delivers communication among billions of smart devices
via the Internet such as smart car, vending machine, smart house, health system and business
system, etc. Nearly 50 billion devises and sensors will be connected to the Internet by 2020 and
most of them will perform their duties without having security. In addition, the critical mission of a
massive interconnected devices are security and interoperability. Hackers will use more complex
tools and techniques to breach the network system. Hence, companies should establish strong
security countermeasures and the best approach to provide superlative is security by deploying
multilayer security method which is called defense in depth. Defense in depth is considered as a
vital part for securing the Internet of Things because defense in depth eludes a system from facing
single point of failure. This paper discusses the seven core layers of defense in depth approaches
which are policy, procedures and awareness, application security, data security, physical security,
host and server security, network and perimeter security, and wireless security. The first layer of
defense in depth are policy, procedures and awareness, which are the most important parts of the
defense in depth. The first part is policy, policy is a set of rules and principles which are written to
govern all organization areas in order to secure the assets. Policy should clearly and accurately

This is an open exposure due to the uncertainties of the internet. Controlling access to information
systems and associated networks is necessary for the preservation of their confidentiality, integrity,
and availability. Confidentiality assures that the information is not disclosed to unauthorized persons
or processes. Any automated attacks or personal attack or attack to exploit the company
secrets/statistics/data is the biggest threat to that may occur without the firewall.
According to the survey, "Perceptions about Network Security," 90 percent of the 583 companies
polled said they've suffered a network security breach at the hands of hackers at least once in the
past year.
Those don't include website hacks, which are annoying but often not serious, or denial–of–service
attacks, which are more like roadblocks than actual hacks.
A company's website is its public face; its internal networks are its concealed valuables. If hacking a
website is akin to throwing toilet paper onto a company's front lawn, then hacking into its internal
networks is like breaking into its house and stealing its jewelry.

Using A Virtual Private Network ( Vpn )
Section 1.0
The world is constantly changing especially in technology. Each day new software and hardware is
created to accomplish tasks that were not possible before. These new software's and hardware's
offers new problems to come with these new accomplishments. Businesses are constantly looking
for ways to make their employees more efficient. Allowing employees to communicate not just in
the office, but remotely is being a requirement at this day and time.
This company could make use of a Virtual Private Network (VPN) that routes through the firewall.
The VPN would allow easy access to the company network for authorized employees. A VPN would
allow the company to have employees that telecommute, work from home, or remote employees. It
would allow our employees that travel frequently – like salesmen – to connect from anywhere they
may be. The VPN would allow for a more flexible work day, and help work get done when it needs
to be done instead of during normal business hours. The VPN will run through the company firewall
to help limit the traffic through to legitimate business traffic.
The company must first be aware and understand the risks of a VPN and firewall. This knowledge
will help the company make the right decision for this technology. A VPN and firewall solution is
different for every network, and must be customized to this company's network. There is also risks
to not using these tools. It is important for the company to see this risks as well, so

SOFTWARE FIREWALLS:
A Firewall basically prevents the private network connected to the internet from being accessed by
unauthorized user and therefore handles the traffic of internet. Hardware and software firewalls are
the types of this network security system. It examines the each data in the network and blocks the
data which is not valid and are from unauthorized user. We will discuss here only software firewalls.
Software firewalls:
Software firewall is suitable for the personal computers at home and it is software so it can be easily
installed by the user and then user can easily manage its properties and functions. Thus we can
protect our system form the unauthorized access and also from different harmful viruses. There are
further two types of software firewalls:
a. Rule based
b. Non– Rule based
Rule based firewalls include firewalls like Norton personal firewall and Non rule based includes

ABSTRACT
In today's world Network Security plays a vital role to protect the underlying network infrastructure
from unauthorized access, malfunction, modification and improper disclosure. Network security
helps to create a security platform for users, programs, and computers. Security became a major
concern with the explosion of the public internet and e–commerce, private computers and computer
networks. This white paper outlines the overview of network security threats and its solution which
protects you and your organization from threats and malware and confirms that data travelling
across your network is safe.

Network Security involves authorization of access to data in a network because each and every
client who is working on the internet wants security and sometimes he or she do not know that
someone else may be an intruder collecting the information. The vast topic of network security is
scrutinized by researching the following.
1. History of network security
2. Attacks and Prevention Method.
3. Role of Network Protocol
4. Pros and Cons
HISTORY OF NETWORK SECURITY Securing information over had started in the late 1960s
when network only occurred in the sense of huge mainframes and several networked terminal.
Network security has advanced day by day due to increasing faith on public networks not to reveal
personal as well as professional information. The first crime was committed by Kevin Mitnick. This
was the largest computer–related crime in U.S. history. In this crime people losses eighty million
dollars from different companies. In the 1970s the birth of internet takes place in 1969 by Advanced
Research Projects Agency Network (ARPANet) is commissioned by Department of Defense (DOD)
for research in networking. In the very beginning, ARPANET succeed. The Inter Networking
Working Group (INWG) becomes the first of multiple

Discuss the Roles and Motivations for Separately Filtering...
Discuss the roles and motivations for separately filtering ingress and egress traffic in the enterprise
network. Describe separate conditions for both ingress and egress traffic as they transit the network.
Discuss: What roles do ingress and egress filtering play in protecting a network? How do protective
isolations help to protect a network? Why do we need to separate and isolate the types of traffic?
Ingress filtering is the filtering of any IP packets with untrusted source addresses before they have a
chance to enter and affect your system or network. It can protect users from malicious attacks based
on spoofing, where a hacker attempts to make a packet look like it originated from somewhere else.
Internet service providers (ISPs) ... Show more content on Helpwriting.net ...
Especially communication between servers has very predefined patterns of communications. By
only allowing this traffic you are sure that no one wills accidently compromise the server by adding
new software, and thus raise the security.
.
The main purpose of egress filtering is to ensure that unwanted or destructive traffic (such as
malware, unauthorized e–mail messages, or requests to Web sites). To create an isolated network,
you need to separate the various types of computers on the organization network according to the
type of access you want the computers to have. The communication requirements are the following:
Computers on the isolated network can initiate communications with all of the computers on the
organization network, including those that are not located on the isolated network.
Computers that are not on the isolated network can initiate communications only with other
computers that are not on the isolated network. They cannot initiate communications with computers
on the isolated network.

Mim Attack Essay
What series of malicious events led up to the incident?
The following events led up to the reported incident. First, an attacker spoofed his IP address to
eavesdrop on the network to find the finance and HR information systems. Second, the employee
hacked into the HR database and increased his salary in the records system. This resulted in the
employee receiving two paychecks with the altered amounts. Third, the employee sniffed the
network to intercept and alter emails about the checks between an auditor and management. Fourth,
the employee impersonated a person who has access to financial records to gain more access to
other financial records. Finally, the employee decreased the company President's paycheck while
increasing his paycheck by ... Show more content on Helpwriting.net ...
Account hijacking – again, this attack's severity is high because the attacker had access to finance
record accounts on the finance information systems.
Email spoofing attack – email spoofing is a medium severity attack because it is an easily mitigated
attack; it is mostly a nuisance to most organizations.
MITM attack – the severity of an MITM attack is medium since the attacker used it to intercept
messages between the auditor and the finance department; it can be easily mitigated with network
and VLAN segmentation accompanied by access control lists; often times, using a layer two switch
mitigates the issue.
Describe how these additional attacks can be prevented in the future.
Mitigate the attacks by using the following techniques:
Encryption – apply encryption to the network with software and hardware solutions. For instance,
software can be used to encrypt the financial records for anyone unauthorized to see the information,
and a hardware solution can be used to build a VPN from any remote

Introduction
Security has been playing a vital role in every sector. But the security is highly essential factor and
parameter in the field of Computer Networking Information system. Secured transmission of data
between sender and recipient is important for both the organization and its customers. High Point on
the security is very much essential so that appropriate strategies will be introduced, which not only
elevates business management avoiding risks in communication. Hence before implementing
computer information, security is a highly considered factor for both healthy business continuity and
an individual. This security is to be properly strategized before initiating the network. Here we
discuss the factors to be considered relative to the network security, challenges and strategies to be
planned before establishing a computer network.

Information Security And The Healthcare
Introduction Information security and privacy is occupying a most important role in the healthcare
territory in order to deliver protected information process to their patients (Appari, & Johnson,
2010). As healthcare department is the organization with vast data and essential information the
hospitals has to keep a useful information security technique in their enterprise process (Mishra et
al., 2011). Information security is one such phase in the healthcare sphere which is extremely
problematic to describe and evaluate even to the individuals who are working on the process. In the
healthcare organization, information is of many types which required for the work and even the
security is a main control for almost all the practices which are transmitted out in the healthcare
field (Appari, & Johnson, 2010). Hospitals, in specific, have been instructed to create a new set of
security specialists to protect healthcare data tools techniques upon which exists may rely.
Healthcare data is very critical for patients because it is very confidential records. If a medical
apparatus is filled with a computer virus it can even exemplify a possibility to patients ' lives.
Hence, hospitals should design alertness of the risk, to defend against concerns to healthcare
databanks and be concerned about the high risk of infected computers or medical tools being
connected to their networks (Mishra et al., 2011).

"Security needs to be addressed as a continued lifecycle to be effective. Daily, there are new attack
signatures being developed, viruses and worms being written, natural disasters occurring, changes in
the organization workplace taking place and new technologies evolving, these all effect the security
posture in the organization" (King, 2002). This being said, it is important to evaluate firewall and
router rule sets more frequently. The possible threats against this policy include improperly
configured network infrastructure which leads to a domino effect that could start with malicious
programming which could end in data loss. Many of these threats may be unintentional as some
users may not be aware of the risks and how their processes and procedures open the door for such
attacks. For this reason alone, a more frequent evaluation is needed. This vulnerability could lead to

data loss and the exposure of trade secrets, client lists and product design. The exposure of such
information for most companies could mean a financial collapse as it no longer has the competitive
edge that makes it the industry leader. While the likelihood of this threat is very high, "security risks
to the network exist if users do not follow the security policy. Security weaknesses emerge when
there is no clear cut or written security policy document. A security policy meets these goals:
i. To inform users, staff and managers of their obligatory requirements

Network Security Is The Procedure Of Computer Or Any...
Network security is the procedure of preventing and identifying unsanctioned use of your computer
or any computer on your network. Preventative measures allow you to stop unauthorized users, also
known as "intruders" or "hackers," from accessing your computer system. Detection helps establish
whether or not someone has attempted to break into your system, if they were successful, and what
they may have done . The Internet has grown to give us the ability to shop, pay bills, and create
online profiles hence, people and businesses need to make the proper steps to secure their network.
And while you may not consider your communications to be particularly interesting or confidential,
its likely that you do not want strangers reading your ... Show more content on Helpwriting.net ...
Furthermore, researchers have developed some newer methods, such as protocol normalization and
distributed firewalls but they have yet to be widely adopted . In addition, because selective data
must be able to pass in and out of a firewall in order for the protected network useful, every attack
cannot be stopped by firewalls. Particular emerging technologies, such as Virtual Private Networks
and peer–to–peer networking pose more modern challenges for firewalls .
Like firewalls, if you put intrusion detectors in place as a preventative measure you could be saving
your network from security meltdown. Intrusion detection is when you monitor the happenings of a
network itself and investigate possible incidents or impending threats of computer security policies
or acceptable use policies. After you put intrusion detection and prevention systems in place, it
mainly focuses on recognizing likely incidents, recording data regarding them, remediation, and
reporting them to security administrators. The remediation process use several response techniques,
which involve the IDPSs hindering the attack itself, altering the security environment (e.g.,
reconfiguring a firewall), or modifying the attack's content . Furthermore, organizations use
intrusion detection for additional purposes, such as looking for holes in security policies,
documenting current threats, and discouraging other individuals from

Computer And Network Security Incidents
Purpose Computer and network security incidents have become a fact of life for most organizations
that provide networked information technology resources including connectivity with the global
Internet. Current methods of dealing with such incidents are at best piecemeal relying on luck,
varying working practices, good will and unofficial support from a few individuals normally
engaged in central network or systems support. This approach undoubtedly leads to inefficiencies
and associated problems with respect to: * Duplicated effort * Inappropriate actions * Poor co–
ordination * Confusion – No obvious authority, identifiable responsibilities or overall management *

It is recommended that the new permanent staff posts be assigned to the Computing Service
department and based within one of the existing central support teams. Additional central support
team resources would be drawn from the following: * Network team – at least 2 members * Central
team – at least 2 members Responsibilities The primary responsibilities of the Core team would be
to maintain the day to day operation; provide advice, monitor for incident alerts and reports, manage
incident investigations and provide follow up analysis and reports to Corporation Techs
management committee; in detail the Core team would be responsible for the following support
activities: * Provide availability for contact and incident response * Produce an incident
classification scheme based on risk assessments for Information Technology resources * Work with
Computing Service central support teams to introduce proactive measures for incident avoidance or
early incident detection * Monitor external and internal sources for alerts and incident reports *
Notify and consult with campus IT support staff, network and systems administrators * Perform

Evaluating The Security Of A System Or Computer Network
Introduction
In this report I will explain three penetrations methods. The three methods are: OSSTMM Method,
DOS and VMs penetrations testing.
A penetration test is a method to evaluate the security of a system or computer network. This
method allows to simulate an attack and find exploitable vulnerabilities to propose an action plan to
improve the security.
There are two types of penetration testing: the pentest in Black Box or pentest in White Box. The
pentester in Black Box mode really puts in the skin of an external attacker, he has no information on
the target. The pentester in White Box mode work in collaboration with the DSI and the technical
team in order to get maximum information for the penetration test.
The objective of pentester can vary according to context:
 List a set of information found in one way or another, and which may be sensitive or critical.
 List the vulnerabilities or weaknesses in the security system that can be exploited.
 Demonstrate that a potential attacker 's capacity to find vulnerabilities and exploit them to break
into the information system.
 Test the effectiveness of intrusion detection systems and responsiveness of the security team, and
sometimes users.
 Perform a final presentation and reporting its progress and its findings to the client.
 Provide ideas and advise on methods of resolution and correction of discovered vulnerabilities.
Nowadays the security of systems or network are constantly changing, quickly evolving, we

The Core Layers Of Defense
Internet of Things is a new technology that delivers communication among billions of smart devices
via the Internet such as a smart car, vending machine, smart house, health system and business
system, et cetera. Nearly 50 billion devices and sensors will be connected to the Internet by 2020
and most of them will perform their duties without having security. In addition, the critical missions
of a massive interconnected device are security and interoperability. Hackers will use more complex
tools and techniques to breach the network system. Hence, companies should establish strong
security countermeasures and the best approach to provide better security by deploying a multilayer
approach which is called Defense in Depth. Defense in Depth ... Show more content on

A good policy should be concerned with providing data confidentiality, integrity, availability,
resource protections, and also should be audited periodically. An example of policy is to send out
critical data via the Internet, the data must be encrypted. The second part is procedures: which are a
detail of the steps and documentations that explain how a particular function or job should be done.
For instance, a detail instruction which tells how a particular program should be installed. The last
part is the awareness and training which is very critical to take into consideration. Thus, all
employees should be trained and aware of general security by providing them with security training
whenever it is necessary and educate them about cyber security.
The second approach of Defense in Depth is application security: applications are programs which
are run by users for multi–purpose tasks. Users directly interact with applications, such as internet
browsing and using email; therefore, applications have more associated with security risk and
vulnerability. Vulnerability is the weaknesses of a system which hackers may take advantage of and
can compromise the system. There are a lot of way to protect applications from intruders, such as
vulnerability scanners which is tools and programs used to detect vulnerability before the attacker
compromises the system. Another security tool is the penetration test which breaks into network
systems after finding the

The Security Of An Organization 's Computer Networks
The security of an organization's computer networks play a critical role in modern computer
systems. In order to have high protection levels against malicious attacks, a number of software
tools have been developed. Intrusion Detection Systems have recently become an important research
topic due to its capability of detecting and preventing attacks from malicious network users.
Security incidents are increasing at an incredible rate every year. As the complexity of the threats
increase, so do the security measures that are required to protect the organization's networks. Data
center operators, network administrators, and other data center professionals need to comprehend

Cyber Malware Programs And The Internet
With the increase in usage of internet in recent time, cases of security breaches, threats and malware
etc. have also increased. One of the major issues in using internet is getting the system infected with
malware downloaded from internet. The malicious programs could be threat at different levels i.e.
from displaying a simple message to making a huge system useless. There are various types of
malwares such as virus, Trojan horses, worms, spyware and adware etc. Sometimes, internet route is
used to infect systems with these malicious programs by embedding malware with useful programs,
emailing malicious programs and various other ways to infect system through internet.
However, increasing malicious programs also led to increase in anti – malware programs to be
developed by various companies like AVG, Kaspersky, Norton and Microsoft security essentials etc.
Apart from the anti– malware programs that could stop malwares from infecting the system or clean
the system if already infected, there are some ways to stop malicious programs from being
downloaded from internet at the first place. For example, firewalls are often used to ensure that any
malicious program should not be downloaded from the internet.

The Problem Of Computer Network Security
Introduction
Computer network security has never been as critical as it is today. The news is littered with the
widespread incidents of hacking and cyber theft in the financial, entertainment, and retail industries,
and more recently in our military. A recent survey, conducted by Kaspersky Lab, a leader in
endpoint protection solutions, found that 94% of all companies surveyed experienced a cyber
security issue (Kaspersky Lab, 2014). Furthermore, a recent study has found that the average cost of
a data breach to a company was $3.5 million, a 15% increase from the previous year (Ponemon
Institute, 2014). In this day and age, the cost of a data breach, not only to a company's bottom line,
but to their reputation, would be extensive.
Statement of the Problem
Recently, Acme Corporation experienced a network compromise which resulted in the possible
compromise of the personally identifiable information (PII) of their employees and clients. As a
start–up company, many technological issues were overlooked in the interest of getting the business
off the ground. Significant emphasis was placed on acquiring the most up–to–date and cutting edge
hardware and software, unfortunately, only mediocre consideration was placed on network security.
This report will examine the factors that contributed to vulnerability and will identify the solutions
that must be undertaken to secure the company network and protect it against future cyber–attacks.

Remote Access And Using Extensible Authentication Protocol...
Remote Access Business today never sleeps in large part to advances in technology. Because of this,
users often need access to sensitive company data outside the office which presents many security
challenges. Not only is the end user accessing your network resources and potentially sensitive data,
but they are many times doing so from a public network which the admin has no control over and is
open to others who may have malicious intent. These connections clearly need to be properly
secured in order provide end users secure network connections. To secure remote connections, a
virtual private network (VPN) will created using the Routing and Remote Access feature available
within Windows Server 2012 R2. This feature allows end users to create a secure connection to the
network by using Extensible Authentication Protocol–Transport Level Security (EAP–TLS) in
addition to smartcards for authentication purposes. Traffic will also be encrypted by using Layer
Two Tunneling Protocol over IPSEC (TechNet, 2016). To implement this configuration properly, the
certificate authority mentioned above will be used to provide certificates to the servers and clients to
authenticate and encrypt transmissions over public networks. The network firewall will be
configured to accept this traffic and direct it to the VPN server. This configuration will allow
secured remote connections to network resources for employees and end users.
