DD2391 Cybersecurity Overview 7.5 credits

Overview of cybersecurity. Cross listed with DD2395 Computer security and DD2394 Cybersecurity project. This means that their content overlaps: DD2391 (7.5 ECTS) is equivalent to DD2395 (6 ECTS) plus DD2394 (1.5 ECTS). DD2391 therefore cannot be combined with DD2394 or DD2395. One can only combine DD2394 with DD2395 and receive credits for both.

Intended learning outcomes

After passing the course, the student shall 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 systems (based on given or self-made system descriptions) to identify vulnerabilities and predict corresponding threats
  • select countermeasures against identified threats and argue for their suitability
  • compare countermeasures and evaluate their side effects,
  • apply countermeasures

in order to

  • be able to develop software and computer systems with security in mind
  • be able to move on and specialise in the cybersecurity area
  • assess the difficulty of a security problem in relation to their own ability to decide when they can handle it alone and when they need to consult an expert.
