Advanced Computer Networks / Mobile Security

Course Number 705010 and 705010 | Sommersemester 2020


This course is a seminar-style class which focuses on security aspects of mobile devices. We study the security mechanisms of smartphones and show how to employ them to protect sensitive information. Based on that, we analyze mobile applications regarding security-critical deficiencies, examine platform and application vulnerabilities and discuss how they can be exploited by attackers.
