Computer & Network Security
Run by School of Computer Science and Electronic Engineering
10 Credits or 5 ECTS Credits
Organiser: Mr Cameron Gray
Overall aims and purpose
To give an understanding of the issues surrounding security in computing, networks and the interconnected world and experience in how to defend their systems against attacks. To expose students to common themes and activities required to secure programs, machines and networks. To give practical experience of the processes and mindset that attackers will use to defeat system security. To present the concept of layered/blended responses.
To differentiate between white and black hat hackers and understand the aims of them.
Definitions and usage of Authentication, Authorisation and Accounting; the weaknesses of various schemes and issues surrounding the storage of data.
Overview of ways in which attacks can be made against networks / computer systems. Methods hackers use to attempt a break in. Wireless networks and their problems
The layered protection model (Onion Response) and methods that allow networks to be protected
Understanding of how encryption works, the two major ‘forms’ of encryption, the provision of confidentiality and integrity guarantees.
Data protection, access to sensitive data and understanding the tactics of social engineers
Learning outcomes mapped to assessment criteria
Understand the background to hacking and cracking and the popular terms used
|Can explain the terms black hat and white hat hackers||Can also explain the difference between cracking and hacking||Can explain in detail the culture and motivations of the aforementioned people|
Explain the ‘3 As’ and their appropriate applications within a business and technical context.
|Can understand the terms social engineering and data protection and what issues arise form both||Explain policies involved in ensuring data is handled correctly||Can give clear examples of all points and explain their desired outcomes|
Explain networks/computer systems vulnerabilities
|Can describe common vulnerabilities.||Can explain common vulnerabilities including how the issue was created.||Explains common vulnerabilities, including cause and selects appropriate methods to mitigate them.|
Understand layered Network protections, the rationale for using them and the popular terms used
|Be able to describe several tools used for discovering problems||Explain how using these tools could help the administrator secure their system||Can explain the possible vulnerabilities networks or systems can have|
Explain the basic principles of encryption, confidentiality and integrity.
|Can explain the terms firewalls and IDS and how they differ||Able to display a deeper knowledge of the two’s functionality and abilities||Can give examples of how both would work together in a network|
Understand Computer Ethics & Social Engineering
|Describes ethical factors and methods of social engineering.||Describes, using appropriate examples ethical factors and social engineering techniques.||Describes ethical factors, argues appropriate cases for actions. Explains social engineering techniques and attacks with supporting theory.|
|COURSEWORK||Reflect and Relate||
A written report reflecting on the practical work completed, its worth to the field and the student.
|COURSEWORK||Red/Blue Team Exercise||
A report on a security exercise on a given system, from either the red or blue team approach. Students may experiment in groups, but the final report must be individual.
