TELECOMMUNICATION NETWORK SECURITY
Introduction
The report is prepared for the development of the network solution for the company
Acme Corporation for connecting its two branch offices and maintain a constant speed of 50
Mbps. The network solution is prepared considering its security such that the database and the
Web servers cannot be accessed by any unauthorized personnel. The network administrator
should design some traps such that the attacker cannot access the core resources of the network
and the security of the network is maintained. The installation of wireless access points in the
network helps to helps the employees to connect their wireless devices in the network and
increase their efficiency. For increasing the availability of the data residing in the data center
separate communication channels are used and the justification of each of the methodology is
given in the report such that the development of an error free network solution.

List of recommended wiring closets
For the backbone of the network Fiber optics cable are used and the internal wiring is
done using the cat 5e or 6 cables. For each of the floor a wiring closet is required to be installed
for connecting the PCs, servers and the data centers with the category 5e/6 patch cord and the
network equipment. A 19” rack or cabinet would be sufficient for installation of the switch and
the connecting the cords with it.
Recommendation for securing the network
For securing the network from being attacked firewalls must be installed in the entry
point of the network for each of the branch offices. The internal network should be managed by

adding access control list and restricting the users to access the core resources such as the data
centers and the web servers.
Building of traps for stopping attackers
Bread Crumbs can be used throughout the network to fool the attacker and lead the
attacker in a particular direction such that original servers and the resources are kept safe.

Recommendation of WAN or wireless technology
For connecting the two offices the cost and the functionality of the network should be
considered. The integration of the voice, video and the data traffic would help the organization to
get the maximum output from then network solution. The monitoring and maintenance of the
network is important for managing all the remote location. Retransmission of the packets should
be implemented for reducing the delay and increasing the reliability of the network. The

installation of the wireless access point in the network helps in connecting the handheld devices
in the network and increases the efficiency of the network (Khan, 2014).
Technology used in data center for increasing the data availability
The virtualization of the data center and the migrating the data in the cloud servers
increases the redundancy and the data becomes available to the users all the time (Rodríguez et
al., 2015). Load balancers should be used for the management of the loads on the server and
increasing the scalability and availability of the resources.
Justification of the recommendation
The cat 6 cable is recommended for the local wiring because it can support a larger
bandwidth than the normal cat 5 cable. A wiring closet is recommend to be installed in each of
the floor such that it can be easily managed. The cables should be labelled such that a broken
link can be easily identified. The bread crumb are used throughout the network such that it does
not cause suspicion on the attacker and the attacker feels that they are really attacking the
network and found the real resource. The data regarding the attack process should be gathered by
the network development team for securing the network in future from illegal access. The
wireless access point must be secured with proper encryption algorithm and the different
VLANS must be created for the data and the voice for reducing the congestion and increasing the
availability of the network. The virtualization and implementation of load balancer for
distribution of the data traffic evenly increases the availability of the data and reduces the risk of
single point failure.

Conclusion
From the above report it can be concluded that with the development of the network
solution for the company the requirement of the company was analyzed. The location of the
server and the cable used for connecting the servers are analyzed for recommending the best
cable and the layout of the cable for designing the network solution. A network design is created
and a list is prepared for the recommended cables that should be used for connecting the two
destinations. The wiring closet that should be used for the installation of the hardware devices
are also given in the report. A list of recommendation is given for the development of a secure
network solution and eliminate the threat in the network for securing the organizational
information.
