Module summary

This module covers the basic concepts of cyber security, how these are modelled, threat models, and the mechanisms to enforce security policies.

Module will run

Occurrence Teaching period
A Autumn Term 2022-23 to Spring Term 2022-23

Module aims

This module will cover the basic concepts of cyber security (confidentiality, integrity and availability), how these are modelled (importance of identity, trust, reputation), threat models (adversary capabilities and goals), and basic control mechanisms to enforce security policies (e.g. access control). Students will learn to understand network security, threats, and the mechanisms that have been developed to counter them. It explores a range of different networked systems, the main network attacks, and their defence mechanisms.

Module learning outcomes

  • Be able to assess the relative merits of different solution approaches in various security-related contexts.

  • Understand and explain the importance of identity, trust, reputation and related concepts, why they are needed and how they are implemented in modern-day systems.

  • Be able to identify major threats to identity, trust and reputation in a variety of system types.

  • Analyse network protocols, identify associated attacks, and analyse security strengths/weaknesses in network mechanisms
