Lecturer: Dr R.J. Anderson (

No. of lectures: 12

Prerequisite courses: Introduction to Security, Discrete Mathematics, Operating Systems, Digital Communication I, Digital Communication II, Information Theory and Coding

This course is a prerequisite for E-Commerce.


This course aims to give students a thorough understanding of computer security technology. This includes high-level issues such as security policy (modelling what ought to be protected) and engineering (how we can obtain assurance that the protection provided is adequate). It also involves the protection mechanisms supported by modern processors and operating systems; cryptography and its underlying mathematics; electrical engineering issues such as emission security and tamper resistance; and a wide variety of attacks ranging from network exploits through malicious code to protocol failure.



At the end of the course students should be able to tackle an information protection problem by drawing up a threat model, formulating a security policy, and designing specific protection mechanisms to implement the policy.
