Administrative Information

Note for students of the discontinued 15U, 15U-A, 16U, 16U-A curricula looking for “Introduction to Information Security”: You’ve found the right place :-) According to the equivalence lists of the new 2019 curricula, “Information Security” VO is equivalent to the previous “Introduction to Information Security” VO, and “Information Security” KU is equivalent to the previous “Introduction to Information Security” KU (and, in some cases, “Rechner- und Kommunikationsnetze” KU) – register for this course and it will count for your curriculum. If you still have questions on the transition, please check our IAIK course equivalence list or contact your student representation Bits or your Dean of studies.

Lecture Exams (VO)

In order to get a grade for the VO, you take a written, 60-minute exam. This is a closed-book exam, i.e., you are not allowed to bring additional material such as slides, notes, or books. We offer 3 exam dates per semester. See above for COVID rules.
Grade 5 4 3 2 1
Min. Points < 24 ≥ 24 ≥ 30 ≥ 36 ≥ 42 of 48

Practicals (KU)

In the practicals, you implement small projects related to the topics discussed in the lectures. The practicals consist of 3 assignments P1, P2, P3 solved in teams of 2 students.

Teams and Team Registration

The KU is done in teams of 2 students. You can use the IAIK discord, channel infosec-groupsearch to find team members. You then register your team at the TeachCenter. Your team will be assigned a random teaching assistent for the assignment interviews.


You are given access to a git repository in our teaching git where you have to push your submission. The required content is discussed in the Kick-Off lectures. You must mark your final submission by tagging it in git. The tag label starts with the assignment (P1, P2, P3), followed by a dash and a number. As an example, P1-1 is the label for the first assignment. As tags cannot be deleted, you may always update your final submission by increasing the appended number: P1-2, P1-3, etc. In the end, the tag with the highest number before the deadline counts. Your submissions will be tested automatically by our test system. Thus, you need to respect and meet file naming constraints of the individual assignments. Otherwise, the tests will all fail and you will receive 0 points for the assignment. After hand-in of each task, there will be a team interview with your teaching assistant. There, both team members need to be able to explain your solution.


You can earn a total of 48 points: 16 for each task. The grading scheme is shown in the table below. You will get a grade as soon as you hand in a solution to P1 by adding a git tag. Groups that do not hand in anything for P1 will not be given a grade and will be unregistered from the course. Note that handing in P1 (even an empty solution) is the only condition for “getting a grade”.
Grade 5 4 3 2 1
Min. Points < 24 ≥ 24 ≥ 30 ≥ 36 ≥ 42 of 48
