Content and learning outcomes

Course contents

The course aims at theoretical and applied knowledge in securing computer networks, including servers, computers, and their software as well as securing the organization wherein they reside. The course deals with securing data communications at the network and transport levels (firewalls, ports, IP tunnels, IPSec etc.) and the application level (authentication, encryption etc.). The course also deals with non-technical aspects of IT- and communication security. Included are societal and economical aspects, but also ethical aspects.

The following is included in the course:

  • General overview of IT security
  • How to work with IT security
  • Management within companies and organisations
  • Encryption methods
  • Authentication and access control
  • IPSec and virtual private networks (VPN)
  • Firewalls and intrusion detection system (IDS)
  • Protection against malicious software, such as anti-virus software
  • Personal integrity
  • Web security
  • Typical security vulnerabilities
  • Other current topics in IT security

Intended learning outcomes

After completing the course, the student will be able to:

  • Analyze an organization’s need for IT-security and to follow a fundamental method for this
  • Prepare and secure a computer network at both the network level and the application level
  • Search for and detect typical security vulnerabilities in IT systems and computer networks and be able to state how to deal with them
  • Plan and carry out a literature study of a limited topic within IT or computer network security and compile and present the results thereof
  • Give an account for how a few security technologies, included in the course, work and can be used
  • Give an account for how a few social, societal, and ethical aspects affect IT and computer network security.
