Module details for Computer Networking 2


This module introduces the ideas and concepts of how computers, mobile devices and gadgets communicate via a wide range of communications technologies with each other and other devices. This will include interactions via technologies such as Ethernet, VLANS, STP, Wireless, Routing, Subnetting, IPv6, SNMP, DHCP, DNS, Firewalls and Network Management


The aim of this Module is to provide the student with an understanding of the key technologies used by computer devices to communicate with each other, along with the skills required to analyse weakness’s in the current technologies and propose solutions that would help to stop the weaknesses.

Learning Outcomes

By the end of this module the student should be able to:

1.  Demonstrate an understanding of the communications technologies which can be used to communicate between network devices.

2.  Critically evaluate the security of a range of technologies used for communicating in a network.

3.  Appreciate the issues of network design and management

Indicative Content


Describe the core concept of VLANS and trunking along with the common attacks that can be used against them


Investigate how STP can be used to create a loop free network and how this can be exploited by an attacker

3 Static Routing

Examine how routing works and show it can be used for pivoting deeper into a network

4 Subnetting and Variable Length Subnet Masks

Classful and classless addressing. Benefits and impact on routing protocols. Design of LANs using VLSM techniques

5 Network Application protocols

Investigation into various networking protocols used at the application layer of the OSI model along with common security weaknesses.

6 Firewalls

Software and hardware firewalls - their application, uses and how to counter them.

7 Intrusion Detection Systems

Examine how Intrusion detection systems work and how they can be bypassed

8 Network Management

Examine network management protocols (Simple Network Management Protocol SNMP) and current practice
