Foundations of Cyber Security II

Hi, 

I just wanted to thank all of you for the excellent evaluation and feedback. Foundations of Cyber Security II was awarded the Busy Beaver Award for the best basic lecture. The entire team is happy to see that our time investment resulted in a lecture that many of you enjoyed. There are also many good comments that will help to improve the lecture further in the next iterations.

Cheers,
Michael

Hi, 

for the exam on Thursday, 04.08.2022 14:00 in E2 2, Günter-Hotz-Hörsaal, there are the following regulations:

• Do not forget to register for the exam in LSF!
• Remember: you need >=112 points on the exercise sheets to be admitted to the exam.
• The lecture-challenge system closes on 03.08.2022 23:59, until then you can collect bonus points for the exam. If you did not register with your student mail address, you have to write your username on the exam sheet to get the points or send me a mail before the exam!
• You are allowed to bring a DIN A4 double-sided handwritten paper cheat sheet containing your name and anything you consider useful for the exam. No other materials or tools are allowed during the exam. 
• All questions of the exam are in English. Answers can be given either in English or in German.
• We strongly recommend you to take a COVID-19 test in case you are not vaccinated or recovered
• You are not allowed to participate in the exam when you observed symptoms of COVID-19. If you provide a doctor's certificate to the examination office later on, the examination attempt will be canceled and will not count
• To get a feeling how the exam looks like, there is a demo exam in the Materials section

If you have any questions, feel free to contact us.

Hey everyone!

Since we want to give you one last in-person opportunity to ask questions about the whole content of this lecture (and because we expect that you are already busy with other exams as well), we decided to skip the last tutorials and instead offer you a grand office hour this Friday, 4 PM, right before the lecture event. There you can ask us any questions about any topic of this lecture.

If you want to participate in-person, you may attend this office hour from 4 PM on (until there are no more questions left and we go to the Ratskeller) in the CISPA lecture hall. Of course, you can also participate in the office hour via Zoom (use Luis' tutorial Zoom link for this).

Note: In case you want to attend on site, please bring a mask as we do not know how many people will come and at CISPA there's still a mandatory rule to wear a mask, if more than 15 people are in the lecture hall at the same time.

Cheers,

Luis.

Hi all,

 

we observed that some angr versions can not solve exercise 2. More precisely, the sample solution does not work with angr in the pip version 9.1.11611.

Hence, we recommend that you update your angr installations [1] to at least 9.2.6 [2] in case your solution does not work. If you have any further problems, you can reach us through the usual channels.

Cheers,

Daniel

 

[1]: If you haven't had angr installed in the first place, you should be fine.

[2]: You can check your angr version with "pip freeze | grep angr"

Hi, 

as some of you (including myself) prefer in-person lectures, I managed to get a different lecture hall for today if you want to be there in person. The location for today's lecture is E9 1 (CISPA), room 0.05 (lecture hall ground floor). The time stays the same. Of course, there will also be the stream of the lecture. 

Cheers,
Michael

Hi, 

Due to the "next Campusmesse", the lecture hall is, unfortunately, unavailable tomorrow. Hence, there will only be a stream of the lecture (link as usual in the Materials section). There will also be a Mentimeter link to ask questions during the lecture. 

I hope to still see many of you in the stream.

Cheers,
Michael

Hi all,

We observed that some of your solutions contain missing or wrong content in the PDF forms. This can easily happen depending on your PDF viewer.

To double-check you could, e.g., download your submission from the CMS again and check whether the file still contains your answers. It is also often helpful to use the Print-As-File function of your PDF viewer and print the submission again as a PDF.

Cheers,

Daniel

PS: This does not mean that all your submissions must use the PDF forms. Feel free to submit other styles of solutions as long as they are readable.

Hi all,

you can now see your feedback for the first exercise sheet on your Personal Status page in the CMS.

Due to a mistake from our side [1], we decided to grade the fourth task as a bonus exercise.

We apologize for the mistake and the resulting frustration on your side!

 

Cheers,

Daniel
