TSIT02 Computer security 2018

The course takes place in period HT2 and can be included in several of our longer educations, is compulsory for students taking the security profile and is also taken by many Master's students, Erasmus students and others. There is a list below that briefly describes the course content, a description of the course goals can be found on another page. The lectures and all literature is in English.


There are 12 two-hour lectures, two two-hour guest lectures, and a lab course that spans the entire course duration. Two two-hour coaching sessions are reserved for each lab group.

The textbook we use for this course is Ross Anderson: Security Engineering (Wiley, 2008). This is a (very) large book, but don't panic -- I will only select parts of it for the course. The book is available online, free of charge, at the author's homepage. If you still want the hard copy (hey, it's cheaper than a gym membership!), it is not so expensive. However, we won't use the book too much during the course so I recommend the online version. The chapters in the course plan below reflects Anderson's book.

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: Cygate

Date: 12th of December at 13:15
Location: VAL

Description: Emerging new technologies introduces new security risks which need to be addressed to highlight the benefits of those technologies.

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.
