Grundlagen der Cybersicherheit 1

dig @198.41.0.4 saarland NS

dig @a.root-servers.net saarland NS

You must not take a shortcut with the domain name of a name server, e.g., you have to use 

dig @198.41.0.4 saarland NS

and not

dig @a.root-servers.net saarland NS

This will yield less points in the exercise. If you already have the NS, e.g., for a given TLD, you do not have to query the root name server again.

There seems to be some misunderstanding regarding plagiarism. In particular, whenever you use an online resource which you just copy, that is considered plagiarism (regardless of whether you provide the URL). All answers are supposed to be in your own words.

Moreover, if you have the same solution as someone other than your submission partner, this is also plagiarism. We have seen cases where two students had the same solution but different tutorials. It is not entirely hard for us to find such cases.

In particular, to be very clear: the first attempt at plagiarism gets you 0 points for that sheet, the second time we forward your information to the Prüfungsamt and you lose the right to take the exam.

I want to take the chance to thank you all for the feedback so far. Since I cannot respond to the anonymous feedback in the CMS, let me summarize and say that I take this seriously (regarding improvable phrasing of the exercises, slide and solution upload).

• We will make all solutions available in the week of January 7th. As for the tutorial sheets, this might take a bit longer.
• The slides are not available before the lecture on purpose. I will consider uploading them, but at the very least without the quizzes). 
• As far as unclarity on the sheets go: if you feel this way, let us know early on. If possible, we can then change them accordingly.

 

Apart from that, I hope you have enjoyed the lectures thus far. If you have taken any reasonable quality pictures in today's lecture, I appreciate if you can share them with me via email.

Merry Christmas!

The lecture recordings up until Lecture 05 have been made available now. Seemingly through our setup, though, there is a bit of audio loss (mostly in the last 10 minutes of each lecture). We are still working with the university to move from a hacky solution with an extra laptop capturing the audio via an antenna to something more usable...

Due to my misjudgement of the timing of today's lecture, I was much too hasty through the padding and padding oracle parts and lost my cool there. Please accept my apology for that. These topics will therefore not be part of the exercises or exams.

To avoid that you forget about this until the end of the semester, I have removed the slides from the PDF version of today's lecture.

I have heard that a number of students showed up last Friday for the lecture. While my group's web site clearly said that the lecture only starts this week, this was not made clear in the CMS and all information pages linked here.

I apologize for this mishap: but on the positive side, this is the only time the lecture will not take place :-)
