Single-Course English 7.5 ECTS

Data Security

Overall Course Objectives

To give students an introduction to fundamental concepts in computer security and introduce central theories and techniques for the development and analysis of secure IT systems.

Learning Objectives

  • 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 security goals;
  • document their work with the security process in a clear and concise report.
