Please come to the Zoom room only at the time you registered for (of course you can enter a couple of minutes early). This Zoom room has a waiting room and we will let you into the call on time. Please make sure to be on time as we cannot exceed the allocated time slots. Also make sure to leave the room again on time.

Please make sure to access the call with video enabled and have your student ID card ready so that we can verify your identity. Please note that this is a hard requirement; if you do not have access to a device that allows video calls, please contact us as soon as possible so that we can figure out another solution that works for you.

We also recommend to have an empty sheet of paper and a pen ready; this might be helpful to make notes when solving scenarios.

Dear students,

I hope all of you are fine and healthy and that you can enjoy the sunshine despite all the hard work. We have received a number of emails from people who want to de-register from this course/the exam. Please note that this is NOT possible due to our grading scheme that allows you to skip one of the assignments OR the final exam. Such a flexible grading scheme requires that all your points contribute towards your final grade (according to university regulations). Hence,  as the registration period has passed you will receive a grade even if you do not submit any more assignments and do not show up at the exam.
We have made this explicit in the kick-off and kindly ask you for your unterstanding and to not send us any more emails on this matter. Thank you!

Dear students,

Thank you for your hard work so far and for all your valuable contributions during the zoom lectures. Unfortunately, I am unable to hold a lecture next Monday, on the 31st of May. The content of this lecture is design methods; we are confident that the best way (and also the most fun way) to learn about design methods is learning by doing, which is why there will be a dedicated assignment (assignment 4) that will allow you to learn about design methods from your own experiences. Nevertheless, we have uploaded a slide deck with instructions for self-study, which you can find under "Materials". Please use your "free time" next Monday morning to go over this slide deck. In case you have questions about the content, please post them in the forum. Second, you will have the opportunity to ask questions in the course of the Q&A session for the 4th assignment. If needed, we will of course also introduce a dedicated slot to discuss the content of this lecture.

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 counselling 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 seminar or deliver your work in time please let me know and we will make appropriate arrangements.
 

Is this the right course for me?


This course is intended for all computer scientists who would like to take an interdisciplinary perspective on the origins of security vulnerabilities. It will also be interesting for everyone who is interested in a societal discourse about the security and privacy of the systems we interact with. In this course, you will have the chance to conduct interdisciplinary research - which means that you will be designing user studies and collecting and analyzing data. You will also have to write code and use statistical testing. Please make sure to take our ungraded statistics self assessment test to understand if your knowledge in statistics is sufficient for this course. Remember that this test is not graded - you can repeat it as often as you want. You can find the test here.
