1. Global Security Law And Act Of Network Security
Introduction
Global Security Law / Act of Network Security
Global security also called International security. International security consists of the measures
taken by nations and international organizations, such as the United Nations, to ensure mutual
survival and safety. These measures include military action and diplomatic agreements such as
treaties and conventions. International and national security is invariably linked. International
security is national security or state security in the global arena. (Wikipedia, 2014)
The Global Security Act also includes Global Network Security. Network security consists of
products and services used to monitor, detect, and prevent unauthorized access, misuse,
malfunctioning, and destruction of a computer network. It helps to provide and maintain a secure
platform to enable users in the network to perform their critical tasks. Network security is
increasingly gaining prominence especially because the number of hackers who want to extort
money or steal critical information has increased. Not only has the number of networks security
threats increased, the level of sophistication is much higher and traditional defense mechanisms are
no match for these threats. Organizations, both large and small, have begun to realize the importance
of network security systems and have increased their investment in network security. In addition,
there is now a growing realization that network security systems can also increase workforce

3. The Components Of Lifecycle Of Network Security
The present era can be referred as a digital era as well, which has created various opportunities for
organizations to conduct business and deliver different services over the internet. The cyber security
is basically a practice that helps organizations minimize risks, helps the security operations in an
effective manner, provide authentication and access control for resources, guarantee availability of
resources and also helps to achieve regularity for enhancing own business network. The basic
components of the security include; confidentiality (maintaining privacy of the data), integrity
(detecting the data is not tampered), authentication (establishing proof of identity, non–repudiation
(ability to prove that the sender actually sent the data), availability (computer assets are available to
authorized parties when needed), and access control (access to information resources are regulated).
The problems of network security include:
increase in network attacks
increased sophistication of attacks
lack of awareness
lack of security policies
lack of proper laws.
The components of lifecycle of network security are plan, design, implement, operate, and optimize.

Introduction
The primary objective of a network security system is to, in a cost effective manner, balance
convenient access to legitimate users and inaccessibility to attackers. In a nutshell, the goal is to
prevent connectivity to anyone intending to cause harm to the network. The harm to which this
paper refers can come in the following forms:
1. Application–level security threats, such as e–mail viruses and attachments.
2. Threats to network infrastructure devices.
3. Theft of network connectivity services.
4. Unauthorized access from internal and external sources.

28, 2001). Because this is an automated system, it depends on a mechanical process of discerning
what is good or bad. This at times can lead to false positives or negatives, or the blocking of a
legitimate user and giving access to a system violator. This weakness in the Cisco IDS requires that
an additional form of violation detection be used.
In addition to the IDS, LADWP has a staff of technicians who provide continuous network
monitoring. In addition to keeping track of the alarms detected by the IDS' Director Platform, these
technicians also use other tools to keep an eye on network traffic levels, as well as performing
routine vulnerability probing. One key tool used is Lucent's VitalSuite. This tool uses real–time
event analysis, which helps to identify network resources that have exceeded acceptable levels.
To properly use VitalSuite, the technicians establish what they believe to be normal network activity.
This norm is then used as a baseline to help in the identification of any abnormal network traffic.
Once the baseline is established, levels of severity are set. The levels are minor, major and critical,
with critical meaning immediate action is required. The only time the system alarms is when a
critical error is detected. During normal operations, the technicians monitor VitalSuites' display,
looking for unusual events. These events can
8. The Practicality Of Network Security
Introduction: As a concept, the practicality of Network Security includes using activities designed to
protect a user's network. Specifically, the core aim for this security is to protect the usability,
reliability, integrity, and safety of data on that network. In Network Securitythere are numerous
applications and software programs that are used by individuals which perform their own roles in
securing network data. The most common and possibly the most essential application used to protect
network data is known as a firewall. A firewall is a program that is designed to act as a barrier
between an external network and the users. It is fundamentally designed to stop hackers, scammers,
viruses, worms, and essentially any unauthorised ... Show more content on Helpwriting.net ...
Looking toward the future with the exponential evolution in technology, it is key to gather a more in
depth and analytical study of the methodologies involved in firewall systems.Observing the current
direction of firewall development can provide an idea of the improvements that can be made to keep
up with an ever expanding technological society; especially as more and more people are being
exposed, uneducated, to the dangers of the internet. Aim: By taking a look at the average household
or business building, it is realised that a common aspect of their basic structure is the physical
security mechanisms in place. These are in place to protect the privacy and integrity of what the
owner possesses within. In terms of a network, this concept of preventing unauthorised access of
one 's property is just as valid. However, in the situation of a network, a firewall is used as this
prevention security system. The idea is simple; a user may have stored, on their network, a certain
amount of private data that is personal to them or their business. Thus, a firewall is put in place in
order to prevent anything or anyone that does not have authorisation from accessing any of this data.
If an unknown and potentially dangerous individual were to try to get into a building complex, the
physical security appliances would react and prevent this from happening. A firewall works the
same way; however it deals with potentially harmful packets entering the network. These packets

10. Network Security And The Security
Hospital Network Security With a multitude of changes occurring in the technology field, it is
critical that hospitals maintain the highest levels of security for their internal network as well as their
public access network. Hospitals contain vital information about patients, treatment styles,
employees and staff, as well as pharmaceuticals that are kept on the premises. The importance of
protecting this information cannot be understated and a breach in security could cause a breakdown
in all areas of the network, having a catastrophic effect on the entire hospital. One of the most
important aspects of network security is a strong network security model. The network security
model consists of seven layers that work together to provide the strongest possible security for the
network. The seven layers are the physical layer, the vlan layer, the software layer, the user layer, the
administrative layer, and the IT department layer. A network security model that is well thought out
and designed allows the network security team to analyze and maintain the network and determine if
there has been a breach and the location of the breach. The first layer of the network security model,
the physical layer, pertains to physical security. This entails the prevention of a physical attack on
servers and other devices connected to the network. The physical layer is one of the most important
layers of protection because if it is breached, the layers beneath it will

15. Network Security : System Security
Network security : System security comprises of the procurements and approaches received by a
system executive to avoid and screen unapproved access, abuse, change, or dissent of a workstation
system and system available assets. System security includes the approval of access to information
in a system, which is controlled by the system head. Clients pick or are appointed an ID and secret
word or other verifying data that permits them get to data and projects inside their power. System
security blankets a mixture of machine systems, both open and private, that are utilized as a part of
ordinary employments directing transactions and interchanges among organizations, government
orgs and people. Systems could be private, for example, inside an organization, and others which
may be interested in community. System security is included in associations, endeavors, and
different sorts of organizations. It does as its title clarifies: It secures the system, and additionally
ensuring and managing operations being carried out. The most well–known and straightforward
method for securing a system asset is by relegating it a special name and a comparing watchword.
The reason for system security, essentially, is to ensure the system and its part parts from
unapproved get to and abuse. Systems are powerless as a result of their inborn normal for
encouraging remote access. Case in point, if a programmer needed to get to a machine not on a

17. Information Security And Network Security
In information security, computer security and network security an Asset is any data, device, or
other component of the environment that supports information–related activities. Assets generally
include hardware (servers and switches), software (e.g. mission critical applications and support
systems) and confidential information. Assets should be protected from illicit access, use, disclosure,
alteration, destruction, and/or theft, resulting in loss to the organization. Security assets are quite
helpful for large or small companies and have many different ways of protecting one's information.
It is quite common to find many individuals involved in compromising a company's intellectual
property. Suspects would most likely be a current/former employee, trusted customers, or
competitors. Therefore security assets are major in protecting and securing a company's information.
The first step to securing intellectual Property is management structure. This will guarantee that
your Intellectual Property will run with a few protection measures implemented. The second step is
Operational Security. This will enable a background check on vendors and third parties. Also, this
will go over existing hiring and departure policies for employees. The third and final step to
securing intellectual property is Cyber security. This will put a stop to network intrusion, safeguard
mobile device security, and remote access security. Protecting a company's intellectual property is

categories that data will fall into whether it be internal, external, general use or confidential. By
doing so you now allow the employees to have a better understanding of what data they can
manipulate and data that has to stay the same.
2. Remote Access Policies – users are always going to want to access the office network from a
remote site. We have to ensure that there are policies in place that allow them to do so but in a safe
manner. If they are going to remotely access the network it has to be done in accordance with the
security policies of the organization and not on their terms. This should include using a laptop or
remote connection software that has been pre–approved by the organizations security team, keeping
IP's in a safe place, making sure that if they are accessing the network from a laptop to ensure that
hard drive is encrypted. This will prevent anyone from gaining access the sensitive information if it
is ever lost or stolen. Lastly not everyone should be granted remote access to the network; this
privilege should only be given to people who have a legitimate need for it.

The security can also be bolstered by hiring alleged attackers that can point out the weaknesses that
are exploited and then these weaknesses can be strengthened by the security professionals.
There are also various techniques that can stop the attacker to access the LAN router so that there is
not attack initiated from the Wi–Fi of a client computer. The LAN router in public places are not
extensively secure and the attackers either use these networks to initiate attack on others so that they
cannot be traced or they can simply attack the users on this network to leak information that is
important.
The protection of HTTPS connection should also be upgraded or security add–ons should be created
to protect the integrity of the browser so that the client cannot be affected by the malicious
JavaScript that is sent by the attacker. There are browsers like Chrome and Mozilla which are not
affected from the attack as they have extensively worked together to ensure that security is not
penetrated or bypassed by the attacker. The other companies should also work in cooperation with
each other to ensure that their security is paramount and that attackers are minimised.

Firewalls are set up on computers to help protect computers and other devices from attacks from
potentially harmful websites and other resources. Proxies are servers that act as a middle man for
computers. They allow users to make indirect connections to other servers. The LAN–to–WAN
domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help
to keep things running and help to keep it protected. The fifth domain is the WAN domain. In this
domain, the network security application that is apart of it is the intrusion detection system/intrusion
prevention system (IDS/IPS). This device monitors the system for malicious activities and reports it
back (Kim & Solomon, 2012). The WAN Domain connects to remote locations and using the
IDS/IPS is crucial because it will help to remote if any outside activity is trying to access the system

As the technology is growing the security threats are also increasing at higher rate. So, as to protect
an organization from such network security threats severe actions and several steps have to be taken
by network security administrators. In any large organization that is having large number of big
servers, firewalls and interconnected network of hundreds of computers, security is one of the most
important aspects so as to secure its network from intruders. Within the organization, all the
computers and devices are interconnected in a LAN network or using a WLAN (Wireless Local

2. Enforcement provides analytical form of all network traffic flows and aim to maintain the
confidentiality(C), integrity (I), and availability (A), also known as the CIA triad, of all systems and
data on the network. In addition, the roles of the CIA triad are:
Confidentiality is set of rules that involve the protection of data from unauthorized entities.
Integrity has a role to make sure the modification of data is controlled in a specified and authorized
manner.
Availability ensures that data are accessible whenever needed by the company (Palo Alto Networks,

Even though the use of the CIA triad to describe security purposes is well recognized, some in the
security area are considered to be necessary to present a complete picture of additional concepts.
The following two concepts are the most common (Stallings & Case, 2012):
Authenticity – The property is original and can be identified and trusted by the business. This means
that users are checked and validated before each input reaches the system which indicated that it
came from a trusted source (Stallings & Case, 2012).
Accountability has the security goal to make sure that the activities of entity could be uniquely
traced to that entity. Organizations must be capable to trace a security breach to an accountable party

The network security manager can equally use intrusion detection systems and anti–virus software
to prevent unauthorized access and blocking harmful viruses and malware from entering a network
respectively. This paper however, does not focus on these approaches but primarily focuses on how
firewalls enhance network security. A firewall is a security technology designed to avoid
unauthorized access to or from a private network. Firewalls can be placed in both hardware and
software, or can also be placed in both hardware and software. Firewalls are usually used to prevent
unauthorized access on a network. All messages entering or leaving the network go through a
firewall, the firewall analyses all the messages and then blocks the messages that do not meet the
security standards. The administrator sets the security standards which packets need to meet, he/she
will decide which packet is suitable to pass through the firewall. (Webopedia.com, 2017), (Services,
2017). Once an administrator has set up a policy, it then needs to be tested to determine if the
firewall has been correctly implemented.

Knowing the attack methods, allows for the appropriate security to emerge. Many businesses secure
themselves from the internet by means of firewalls and encryption mechanisms. The businesses
create an "intranet" to remain connected to the internet but secured from possible threats. Several
key events contributed to the birth and evolution of computer and network security. Back during the
first World War, the Allied army was having trouble deciphering secret German messages, while
their own became heavily compromised. However, Polish cryptographers created an enigma
machine in 1918 that converted plain messages to encrypted text. In 1930, Alan Turing, a

Unfortunately, none of the current solutions scale particularly well. Two general approaches
dominate this area:
1. Virtual Private Networks: When a virtual private network is implemented, the lowest levels of the
TCP/IP protocol are implemented using an existing TCP/IP connection. There are a number of ways
to accomplish this which tradeoff between abstraction and efficiency. The advantage this gives you
in terms of secure data transfer is only a single step further away. Because a VPN gives you
complete control over the physical layer, it is entirely within the network designer's power to
encrypt the connection at the physical (virtual) layer. By doing this, all traffic of any sort over the
VPN will be encrypted, whether it be at the application layer (such as Mail or News) or at the lowest
layers of the stack (IP, ICMP). The primary advantages of VPNs are: they allow private address
space (you can have more machines on a network), and they allow the packet encryption/translation
overhead to be done on dedicated systems, decreasing the load placed on production machines.
2. Packet Level Encryption: Another approach is to encrypt traffic at a higher layer in the TCP/IP
stack. Several methods exist for the secure authentication and encryption of telnet and rlogin

There are threats to network security that can compromise your computer systems. Viruses are one
of the top security threats in the technology industry. A virus is a program or a code that is loaded
into your computer system without your knowledge will run against your wishes (Beal, n.d). Viruses
can also replicate themselves. All computer viruses are manmade and a virus can make a copy of
itself several times and easy to create (Beal, n.d). Mark Vernon wrote that 72% of all companies
have received infected e–mails or files last year and for larger companies the percentage was 83%
(Vernon, 2004). The top viruses in malignancy are Worms and Trojan Horses (Vernon, 2004).
Another threat to network security is malware. Malware (malicious software) is a annoying or
harmful type of software that is intended to secretly access a device without a user's knowledge.
There are different types of malware, which include spyware, phishing, viruses, adware, Trojan
horses, worms, ransomware, rootkits, and browser hijackers ("What is Malware and how to remove
it | Cyber security," n.d.). Malware gets access to your device through the internet, email, hacked
websites, toolbars, music files, free subscriptions, toolbars and anything downloaded from the web

theft. Outside hackers pose the greatest threat. These thieves target a company's network and steal
information through vulnerabilities that they have found in their networks. They usually gain access
through the use of a Trojan horse, which is a program that looks legitimate but can be used by others
to gain access to the network. They may also use a virus or worm, which can infiltrate a network
with malicious code and replicate itself in a network. Others try to gain entry by attempting to crack
the network passwords or user accounts. We hear in the news how networks that were supposed to
be secure were breached and information was stolen that could have negative consequences. Yahoo
discovered that their network had been attacked continuously for the past two years but only
recently discovered it. Information that was stolen ranged from users birth dates to passwords that

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.
