Course content

The techniques presented have for several years been used in design of real time systems and other distributed systems. We concentrate on systems of interacting actors and model such systems in UML. Sequence Diagrams of UML are the core notation for intuitive and formal description of interaction patterns. Topics of the course include:

  • theoretic foundation for UML,
  • refinement concepts in a UML context,
  • modularity through contract-oriented specification,
  • modular security risk analysis.

Learning outcome

After having completed this course you can:

  • make software that is easy to analyse with respect to security and reliability and still easy to maintain.
  • understand how practical software development can benefit from theories about state machines, refinement, security risk analysis, formal reasoning, and modularity.
  • perform a simple security risk analysis.

Admission to the course

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

It may be useful with knowledge of modeling and formal methods, but it is not necessary.

Overlapping courses


The course is divided into three batches focusing on modeling, refinement and safety analysis, and there is a mandatory assignment per part that must be passed.

There are three hours of lectures and two hours of group tuition each week.


4 hours final written digital exam. All mandatory assignments must be passed before the exam.

It will also be counted as one of your three attempts to sit the exam for this course, if you sit the exam for one of the following courses: INF5150 – Unassailable IT-systems (continued) , INF9150 – Unassailable IT-systems (continued), IN9130 – Unassailable IT-systems
