Content and learning outcomes

Course contents

The course is about technical network security. Different aspects we consider are authentication problems, email security, IP-security, Web-security, firewalls, different types of attacks, how to protect routers and infrastructures. The knowledge of these areas will be useful in securing a network against intruders.

Intended learning outcomes

The course teaches how to get a secure computer network. Both threats and countermeasures will be considered. The course is a continuation of the course in computer security and gives a working knowledge of central security mechanisms both on network level and application level.

After the course the student is expected to:

  • know how to use the established terminology and how to describe technical and practical problems in the network security area,
  • know about the most common types of attacks against networks and know how to apply countermeasures,
  • understand the structure of security protocols and know how to work with modifications of them,
  • have the ability to analyse and evaluate networks with regard to security aspects,
  • be ready to participate in investigations and development work in network security.
