Usability is a key aspect of security mechanisms. We are currently working on usability issues related to the configuration of run-time security policies. We are developing the tool JPerm for setting up Java security policies at runtime, to study user behavior, and to test possibilities for user support when users are confronted with security alerts. This work is motivated by our previous work on secure execution environments for e-services.
