Dear Students,

the main exam inspection will take place on the 10th of August between 14:00 and 16:00 in the Günter-Hotz lecture hall.

In order to ensure an orderly and safe exam inspection the following rules must be adhered to:

  • It is absolutely necessary to bring a protective face mask with you. Students who have a doctor’s certificate that they cannot wear protection masks have to bring their own face shields and wear these instead of a mask.
  • You must wear the protective mask when entering or leaving the room as well as when talking to each other, e.g., for questions.
  • We assigned time slots for each student based on the first letter of the last name:
    • A-L from 14:00 to 15:00
    • M-Z from 15:00 to 16:00

If your answer is "yes" to one or more of the following questions, then you are not allowed to attend the exam inspection. Did you have definite contact with a Covid-19 patient, who was tested positive, in the last 14 days?

Do you have any of the following symptoms?

  • Cough / Husten
  • Sore throat / Halsschmerzen
  • Nasal congestion / runny nose / Schnupfen
  • Diarrhea /Durchfall
  • Fever /Fieber
  • Aches and pains / Gliederschmerzen
  • Loss of smell (e.g. no longer able to smell burnt food) / Geruchsverlust
  • Loss of taste (e.g. unable to distinguish when food is burnt) / Geschmacksverlust”

Main Exam Inspection

The inspection of the main exam will be held on the 10th of August in the GHH lecture hall from 14:00 to 16:00.

Please be patient with the exam results. We will publish them before the exam inspection, but it will likely take 2.5 weeks until we can publish the results.

This is a gentle reminder to register for the upcoming CySec II exam by Monday, July 13. Timely registration is mandatory in order to participate in the exam. We cannot allow registrations past this deadline, as per guideline by the study dean. You are allowed to sign up for the exam(s) if you have achieved 92.5+ points in the exercise sheets. If you are below this threshold, you cannot participate in either exam.

Dear students,

we encourage forming groups for the exercise sheets. As such, we extended the deadline for group building for the second exercise sheet until Monday at midnight (18. May 2020, 23:59). Please, use this time to search for a team member if you have none so far. You can use the Askbot or the tutorial sessions on Monday to do so.

For technical reasons, we have to postpone the exercise submission to Tuesday. Thus, you can hand in the exercise sheet from Tuesday until Thursday 13:59. This should not stop you from working on the sheet earlier.

Starting with the third exercise sheet, the deadlines will be as before, with the group building starting on Mondays and submission opening on Saturdays.

CySec II -- Getting Started (READ THIS)

We have several news about the CySec II lecture. Please read them carefully.

Lecture Videos

We have just released the slides, videos and book materials of the first three topics (actually, two, plus some introductory notes). You can find them on YouTube. Further topics will follow as the lecture progresses, latest one week before the lecture.

Note that we're still in the learning phase to perfectionate the lecture videos. There are known minor issues in the first 2-3 videos that will be fixed in upcoming videos (e.g., clearer handwriting, 1080p quality, no overlap between the multiple inputs). If you have further suggestions for improvement, please send us an email or use the CMS feedback form. We will try to incorporate your feedback to the extent possible. Finally, note that we will list errata in the video descriptions, so please pay attention to them.

Live Lectures

On May 7 at 2pm, we will start our weekly live lectures using Zoom. Live lectures will feature a Q&A session, deepen some of the contents with additional slides, and a live online quizz. Attendance is not mandatory, but highly advised. Find the Zoom link, meeting ID and password on the CMS "Materials" page. You can also dial in via phone (details here). To spare resources, we will disable videos of all participants, and also initially mute everyone. If you would like to ask a question, please use the "raise hand" feature in Zoom. Please test your hardware setup before the lecture not to miss any content on the first day. Experience has shown that technical problems may arise that require some debugging.

In the third lecture week, we have to "evade" a holiday (May 21, Corpus Christi) and move our lecture to May 20, Wed, 2pm. Please understand that we cannot just drop this lecture, as we already have lost quite a few weeks due to the delayed semester start.

Reexam date

We moved the re-exam to Fri Oct 16, 10am, to comply to the exam period recommendations by the CS department.

Exercises

The first exercise sheet will be available right after the first lecture on May 7.

You'll be allowed, and actually highly encouraged (!!!), to work on the exercises in groups of two students. In this term, without any doubt, it will be harder to find group partners given the lack of physical presence. To foster the process of forming groups, we offer the help in terms of an Askbot thread where you can leave your contact details in case you're still looking for a team partner (which basically should be the vast majority of you). Don't be afraid of forming groups already now. Groups can be rearranged with every exercise sheet, so you will not enter a long-term commitment should you become unhappy about your partner. We will treat individual and groups submissions fully equally, thus working in a group will lower your effort.

Once you've formed a group, use the CMS group feature to indicate your team members and submit your exercise solutions. As we'd like to allow group changes over time, please note that you have to re-specify your team mate in CMS for every submission even if it did not change from the previous one.

Foundations of Cyber Security II

Given the current COVID-19 pandemic and UdS current recommendations, CySec II will start on Thu, May 7 at 14:00pm s.t.

We are currently preparing online learning materials for the course. CySec II will follow a flipped classroom model. That means:

  • (Likely all) lectures will neither require nor allow your physical presence in the lecture hall
  • Instead, you can download lecture videos & additional materials and study at home
  • Weekly Zoom-based video conferences Thursdays 2pm s.t. (exception: Wed, May 20 2pm instead of Thu, May 21) with the lecturer to discuss your questions
  • Weekly tutorials will be done using Zoom-based video conferences
  • Written exams on July 20 at 10am, and on October 16 at 10am

Please register to CySec II in CMS ASAP to keep informed by news posts in CMS.

Weekly tutorials will start on Monday, May 11. Note that we will streamline tutorials this year, given the digital format. That means that we will offer just two tutorial slots, but allow both of them to scale to many attendees. We picked these two time slots carefully such that they do not collide with other lectures of the 2nd term, nor with major tutorials (except MfI 2 tutorials, which are spread across the entire week). To give you some flexibility, you can change your tutorial at any time, or even attend both.

In addition to tutorials, we will feature Askbot (see CMS menu, "Askbot"), a Stackoverflow-like system to discuss questions about the lecture and its content. Askbot will be closely monitored by the CySec II teaching assistants and tutors to provide you early (digital) feedback.

Online Lecture (Thu 2-4pm) Zoom meeting dial-in details:

You can join the Zoom meeting via computer & Zoom client. The Zoom links are in the Material Section ("Zoom data").

Dial-in to meeting ID 927 4624 2917 is also possible using by phone using the following numbers:

  • +49 695 050 2596
  • +49 69 7104 9922
  • +49 30 5679 5800
