We at the Institute of Application Security are interested in the broad spectrum of security and privacy that exist on the application level.
This includes the detection of vulnerabilities in source code or protocols, identification of novel security issues, and the development of procedures and tools to prevent security vulnerabilities.
Our current research focus is on the topics of software security including web application security, honeypots, fuzzing, novel privacy securing measures, the design and evaluation of security relevant protocols.
