Usable Security & Privacy 
(held as block course from 13.3.23 - 31.3.23)

 

In this lecture, you will learn about human-centric aspects of IT security. Besides research and design methods, you will learn about hot topics in usable security such as authentication, confidentiality and privacy. In particular, you will learn to

  • design user studies to study how humans interact with security & privacy technology with respect to threat models, 
  • collect, understand, evaluate qualitative & quantitative data,
  • interpret results and draw conclusions based on your data,
  • design new security and privacy technology that is better tied to the users' needs and values.

Prerequisites: CySec1/CySec2 or Security, Statistics. It is also strongly advised to take our statistics self-assessment quiz found here. These are the topics that are needed in order to follow this course and they won't be covered in the scope of this lecture.


Please make sure to allocate enough time to work on the assignments for this course. Programming skills and profound knowledge of statistics and data analysis are required. If you have not yet completed any security courses BUT have a strong background in human-computer interaction, psychology, or design you are still welcome to attend this interdisciplinary lecture. In that case, please contact us to directly to discuss whether this is the right course for you.

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. You can find the test here.
 

Mental Health

Being a student can be challenging and might be very overwhelming at times. 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 lecture, tutorial, or deliver your work in time please let us know and we will make appropriate arrangements.
