Cybersecurity MA

Beschreibung

Software applications have become an integral part of daily life, sharing information across devices pervasively and seamlessly to conduct and ever growing number of computing operations. One of the results of software application ubiquity is the complexity of designing and maintaining these applications in ways that guarantee security in addition to reliability and availability. Main stream press examples of data and application breaches such as the case of the MyFitnessPal security breach in 2018 that resulted in hackers acquiring the private data of more than 150 million users, underline the importance of secure design and coding. The goal of this course therefore, is to learn how to identify, fix, and prevent security vulnerabilities.

In order to achieve this, we will study the principles, methods, and approaches needed for the development of secure applications such as web, mobile, and classic applications. This will be achieved through a series of twice weekly lectures during the winter semester, focused on studying methods of analysing software applications to identify and analyse vulnerability classes and corresponding attack vectors on a theoretical as well as practical level.

Topics to be covered include:

  • Confidentiality, privacy and trust management
  • Secure databases 
  • Secure distributed systems
  • Flaws (Vulnerabilities) in Applications
  • Threats and Attack Vectors
  • Data Flow and Interprocedural Analysis
  • ...
