General Objectives

The objective of the course is to provide an introduction to the basic concepts of computer security for graduate level students. The course contents include: security concepts, such as confidentiality, integrity, authenticity, availability etc. Symmetric and asymmetric cryptography and their uses; key distribution and digital signatures; discretionary and mandatory access control policies for confidentiality and integrity. Communication protocols for authentication, confidentiality and message integrity. Network security; system security, intrusion detection and malicious code. Security models and security evaluation. Administration of security. Legal aspects of computer security.

Learning objectives

A student who has met the objectives of the course will be able to:

Course Format

The course is given as a combination of lectures, given by the course lecturers, and practical laboratory work.


Many lectures will be based on the following text book (copies are available at Polyteknisk Boghandel):
C. P. Pfleeger & S. L. Pfleeger: "Security in Computing", fifth edition, Prentice Hall, 2015.

We will however also cover topics that are not described in this book in much depth, and for this we will provide lecture notes/slides and references for further reading.

Laboratory Work

The laboratory work consists of a number of small assignments, most of them mandatory, which will take place in the databars. These assignments are designed to provide hands-on experience with different security technologies and will typically involve a limited programming exercise, which will be documented through a small report (4-8 pages).
