Guest lectures

These seminars are not a compulsory part of the course, but provide interesting insight in how security is used in the industry.

Guest lecture 1: Bodforss consulting.

Rikard will talk about a critical vulnerability he discovered five years ago and some of the challenges in the disclosure process. The talk is a spin-off on the presentation he gave on CS3 Sthlm. In the second part of the lecture Rikard will discuss the security profession as a career path. What should you do if you want to pursue a career in IT and information security. What is the value of certification, and what experience is good to have. Finally some tips on how to kick start your career in the wonderful field of IT and information security.

Examination

A written examination three times a year. See the central schedule for examinations. Previous exams can be found in Lisam.

The examination will contain questions from the level of merely repeating and explaining facts to drawing advanced conclusions from knowledge in the subject. In order to pass, a student should be able to repeat facts about basic principles and typical countermeasures, to understand the concepts used, and to identify relevant basic security concepts in simple situations. For higher grades, the student should be able to do more detailed analyses, to apply general concepts in more complex situations and to draw conclusions from this application of general principles. Knowledge of specific details in products and protocols, such as how to change permissions in UNIX, how to use an NSF log, etc is not required.
