Time: Wednesday afternoon (module E5B)
Examination: Written examination and reports.

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.
A student who has met the objectives of the course will be able to:
- identify all major factors that have to be addressed in
a security analysis of a particular system;
- define operational security goals for a given computing system;
- analyse an application scenario and identify common
threats, vulnerabilities and risks;
- identify possible countermeasures against threats and
vulnerabilities in a given security scenario;
- compare and contrast the underlying security mechanisms
needed to implement security countermeasures;
- define operational security policies to achieve
specific security goals using specific security mechanisms;
- design a security infrastructure that implements an
operational security policy;
- use contemporary tools to analyse and implement (part
of) a security infrastructure;
- evaluate (informally) a given set of security policies
and mechanisms in a given application context in order to
determine whether they are likely to satisfy a given list of
- document their work with the security process in a
clear and concise report.
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.
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).
