3. In this network we will use CAT5 and CAT6 patch. These closets should be used in the server room of the location at Atlanta location and we shall also create one at the Cincinati location due to the big number of hanging wires that we shall use.
4. Wireless networks are much more susceptible to unauthorized use than cabled networks. We should encrypt the network by putting a password to keep out unauthorized access that may lead to network attacks.
I recommend that we turn off all the remote control related features because hackers at times try to breach our network wirelessly. For an intrusion to occur, it can either be from within the organization or even other breaches that come from outside the organization.
I recommend that we put in place packet sniffing measures in our network in order to detect any attacks that are targeted to our network. These may include worms, Trojan horses, botnet, malicious malware etc. The packet sniffers will help us identify when someone is trying to hack into the network.
I also recommend network segmentation where by the network is split into different classifications. This eases the placing of security levels and policies on the network.
We should also put in place physical security in order to curb problems like break-ins in to the server rooms by attackers especially those working in the organization. We should do this by putting in place some policies and levels of restriction because it can lead to data loss.
We should put in place a Virtual Private Network. A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses SSL to authenticate the communication between the devices and network.
I also recommend the use of firewalls in the network security module. Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to block or to allow traffic. A firewall can be software, hardware, or both.
I also recommend the use of access control measures for example passwords, finger print scans, iris scans etc. Not every user should have access to your network. To protect yourself from potential attacks, you need to recognize each user and each device. Then you can enforce your security policies. You can also block out the noncompliant end-point devices or provide them with limited access. This process is referred to as network access control (NAC).
6. I recommend the use of an access server. An access server acts as a concentration point for dial-in and dial-out connections which is perfect for our network model.
I recommend the used of WAN Switch. A WAN switch is a multiport internetworking device used in carrier networks. These can be used to connect de.

Network security architecture is the planning and design of the camp.pdfaquazac
Network security architecture is the planning and design of the campus network to reduce
security risks in accordance with the institution’s risk analysis and security policies. It focuses on
reduc-ing security risks and enforcing policy through the design and con-figuration of firewalls,
routers, and other network equipment.
Network security is important because it is one of the means to enforce the policies and
procedures developed by the institution to protect information. It is often referred to as the “front
door” in broader discussions of IT security. To the extent that you can block network access to a
computer, you “lock” the door and provide bet-ter protection for that computer and its contents.
Traditional network design has focused on creating a secure net-work perimeter around the
organization and strategically placing a firewall at the point where the network is connected to
the Inter-net. For higher education, this traditional design is problematic; our constituents need
access from off campus to a large number of machines and services on campus. In addition,
because we have many computers on our campus that we cannot implicitly trust, we also must be
concerned about security threats from inside the perimeter protected by a traditional firewall.
These design issues require a different approach to network security. Although it is impossible to
do justice to the topic of network design in a few pages, there are some best practices that I feel
universities should focus on in terms of network design.
Step 1: Eliminate Network Components That Still UseShared Ethernet
Shared Ethernet switches (or hubs) were developed more than a decade ago to interconnect
multiple computers and networks. These hubs retransmit all network traffic to all computers
connected to that hub. The security implication is that if one computer has its security
compromised it can be used to monitor network traffic com-ing from any other computer that
shares the same hub. This could expose passwords and other sensitive information. Today,
switched Ethernet, which isolates traffic intended for one computer from the view of others on
the same switch, is very inexpensive and, hence, it is worth the cost of replacing older hubs.
Step 2: Embrace and Implement the Concept of Defense and Use Multiple Firewalls Within
Your Network
Commercial and Linux-based firewalls are inexpensive enough that you can deploy these in
multiple locations as needed. It is still bene-ficial to have a firewall separating your institutional
network from the connection to the Internet. This firewall, called a border firewall, will provide a
minimal level of protection for all computers on your net-work. The major benefit of this firewall
is that it allows your network and security staff to quickly block external access should a threat
arise, such as when the “SQL worm” was launched in January 2003 In addition to the border
firewall, consider adding internal firewalls to protect areas that requi.

Types of Networks
Week7 Part4-IS
RevisionSu2013
Types of Networks
There are different types of networks. Each type has different characteristics and
therefore different security needs. Some of the fundamental differentiating attributes of
the various types of networks are:
the physical distance the network spans
the topology of the network nodes
the types of media used for communication between nodes in the network
the different devices supported on the network
the different applications supported on the network
the different groups of users permitted on the network
the different protocols supported on each network
Depending on the type of network there may be different information security
requirements requiring that various protocols, security services, security mechanisms are
used in a fashion to support that type of network.
While each network environment has some characteristics and security needs unique to
that environment, there are many security techniques that should be universally applied to
all environments. For example; sound policies and procedures, risk assessment of the
assets, user awareness training, encryption technology, authentication technology, sound
credential (password) selection and protection, malware protection, firewalls are a few
security techniques that need to be applied in all of the networks albeit in configurations
that best suits a particular environment.
Local Area Network (LAN)
A LAN network covers a small geographic area that takes advantage of high speed data
transfers usually implemented through Ethernet or fiber. A LAN could be a home, office,
group of building with local proximity (university, business). LANs typically share
resources such as file servers and printers.
Wide Area Network (WAN)
A WAN covers a large geographic area that may require connection through satellite,
high speed dedicated lines and other means. The internet is a WAN. WANs can connect
LANs together into a larger organizational structure that can be used to share resources
such as file, email, dns servers to name a few. Resources can be shared using slower
connections on geographically separated areas across the WAN.
Wireless Networks and Mobile Networks
The movement to laptop systems at home and workplaces accelerated the mobility of
computing.
As employees traveled between offices, client sites, home and various other remote
locations they could remain connected to company servers as long as the remote site had
connectivity to the companies’ intranet. Initially this connectivity was provided by
having Ethernet cabling available for remote users to physically plug their laptops into.
Eventually, companies started installing wireless hotspots that could be automatically
detected by systems that had wireless cards.
The proliferation of wireless connectivity and internet use spread from the workplace to
genera ...

4. Confidentiality
Ensures that data or an information system
is accessed by only an authorized person.
User Id’s and passwords, access control
lists (ACL) and policy based security are
some of the methods through which
confidentiality is achieved
5. Integrity
Integrity assures that the data or
information system can be trusted. Ensures
that it is edited by only authorized persons
and remains in its original state when at
rest. Data encryption and hashing
algorithms are key processes in providing
integrity
6. Availability
Data and information systems are
available when required. Hardware
maintenance, software
patching/upgrading and network
optimization ensures availability
7. NETWORK SECURITY
Network security consists of the provisions
and policies adopted by a network administrator to
prevent and monitor unauthorized access, misuse,
modification, or denial of a computer network and
network-accessible resources. Network security
involves the authorization of access to data in a
network, which is controlled by the network
administrator. Users choose or are assigned an ID and
password or other authenticating information that
allows them access to information and programs
within their authority. Network security covers a
variety of computer networks, both public and
private, that are used in everyday jobs conducting
transactions and communications among businesses,
government agencies and individuals.
8. FIREWALLS
A firewall is
a hardware or software system
that prevents unauthorized
access to or from a network.
They can be implemented in
both hardware and software,
or a combination of both.
Firewalls are frequently used to
prevent unauthorized Internet
users from accessing private
networks connected to the
Internet. All data entering or
leaving the Intranet pass
through the firewall, which
examines each packet and
blocks those that do not meet
the specified security criteria.
Types of firewall:-
Network layer or
packet filters
Application-layer
Proxies
Network address
translation
9. Network layer or packet filters
Network layer firewalls generally make their
decisions based on the source
address, destination address and ports in
individual IP packets. A simple router is the
traditional network layer firewall, since it is not
able to make particularly complicated
decisions about what a packet is actually
talking to or where it actually came from.
Modern network layer firewalls have become
increasingly more sophisticated, and now
maintain internal information about the state of
connections passing through them at any time.
10. Application-layer
Application layer firewalls defined, are hosts
running proxy servers, which permit no traffic
directly between networks, and they perform
elaborate logging and examination of traffic
passing through them. Since proxy applications
are simply software running on the firewall, it is a
good place to do lots of logging and access
control. Application layer firewalls can be used as
network address translators, since traffic goes in
one side and out the other, after having passed
through an application that effectively masks the
origin of the initiating connection, Chris Partsenidis
says.
11. Proxies
Proxy firewalls offer more security than other types
of firewalls, but this is at the expense of speed and
functionality, as they can limit which applications
your network can support.In Proxy firewall traffic
does not flow through a proxy. Instead, computers
establish a connection to the proxy, which serves
as an intermediary, and initiate a new network
connection on behalf of the request. This prevents
direct connections between systems on either side
of the firewall and makes it harder for an attacker
to discover where the network is, because they will
never receive packets created directly by their
target system.
12. Network address translation
Firewalls often have network address
translation {NAT} functionality, and the hosts
protected behind a firewall commonly have
addresses in the "private address range“. Firewalls
often have such functionality to hide the true
address of protected hosts. Originally, the NAT
function was developed to address the limited
number of IPv4 routable addresses that could be
used or assigned to companies or individuals as
well as reduce both the amount and therefore cost
of obtaining enough public addresses for every
computer in an organization. Hiding the addresses
of protected devices has become an increasingly
important defense against network
reconnaissance
13. Problems of CIA Triad
Although the CIA triad is a fundamental
model for information security, it also
focuses on a limited view of IT security
that is centered on information. While the
priority is to protect the information and
ensure that data resources are available,
the CIA model does not address
prevention of an unauthorized person
from using the system’s hardware
resources.
14. Another issue is the information security
professionals will concentrate on the
“confidentiality” part of the triad, essentially
ignoring the other components of a balanced
security approach. For instance, when the
“accessibility” component of the triad is
neglected, this could mean severe disruptions
to communications, costing millions and
significantly impacting an industry. Thus, it is
necessary for security professionals to
contribute skills and knowledge during the
purchasing and selection process for an
organization’s communications network.
15. Conclusion
This Presentation gives a glimpse about
the security concerns for E-Commerce
and requirement for a secure E-
Commerce environment . It comprises of
Security Triads I.e C.I.A (Confidentiality
, Integrity, Availability). It also explains
