Content and learning outcomes
Course contents
Intended learning outcomes
After passing the course, the student should be able to:
- identify threats against confidentiality, integrity and availability in digital systems
- explain basic terminology and concepts in computer security and use them
- find and use documentation of security related problems and tools
- analyse simple program code and system descriptions to identify vulnerabilities and predict their corresponding threats
- select countermeasures against identified threats and argue for their suitability
- compare countermeasures and evaluate their side effects,
- present and explain their reasoning to others,
in order to
- be able to develop software and computer systems with security in mind
- enable those interested to move on and specialise in the field of cybersecurity.
