Run-time security evaluation (RTSE) for distributed applications

摘要

Formal security specifications for a distributed application can be checked for compliance at run-time using executable security assertions. We propose the run-time security evaluation (RTSE) method which makes use of histories/traces of events, assertions and operational evaluation in the distributed environment to ensure the security specifications for the application are fulfilled at run-time. A model problem is used to aid in developing the security requirements formally.
