Security

The Security core lecture ("Stammvorlesung") will be offered in the winter term 2022/2023.

 

Lectures

We plan to offer the lecture in a hybrid format, meaning we will offer an in-person lecture and also stream it via Zoom, a recording will be available after each lecture. Depending on the Corona situation and other circumstances, we might move to an online-only version later in the semester.

The schedule for the two lectures per week is as follows:

  • Tuesday 14:15-15:45 (HS 002)
  • Thursday 10:15-11:45 (HS 002)

 

Registration

Registration in this CMS is required until November 6, 2022. LSF exam registration is required to participate in the exams (and will be possible until ~1 week before the final exam).

 

Tutorials

Tutorials will start in the week of November 7 and will be held once every two weeks. We will offer both in-person and online tutorials. We will soon provide registrations for Tutorials via CMS.

Mental Health

Being a student during a pandemic is challenging and might be very overwhelming. If you need support during times of struggle, reach out to friends, family, or faculty you trust. The student union at UdS also offers a counseling service that you may contact. You do not have to go through this alone! If for whatever reason (e.g. a personal emergency) you cannot attend the lectures or deliver your work in time, please let us know and we will make appropriate arrangements.
