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 any material such as notes or books.
You can earn a total of 48 points: 8 for each of 6 question pages. Each area (Cryptography, System Security, Network Security) is represented by 2 question pages.

You can find upcoming exam dates in TUGRAZonline.
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
ISEC Discord, channel
infosec-groupsearch to find team members.
You then register your team on the
infosec test system.
Your team will be assigned a random teaching assistant for the assignment interviews.
Submission
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 is based on the assignment:
P1,
P2, and
P3.
As an example,
P1 is the tag label for the first assignment.
Before the deadline, you can change your tag if need be.
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 a teaching assistant.
There, both team members need to be able to explain your solution.

Grading
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”.

We treat the involvement of ChatGPT and similar tools the same way as the involvement of another natural person.
That is, for involvement that qualifies as plagiarism or an impermissible level of assistance, the consequences will be the same in both cases to the strictest extent possible.
