GenericBreakGlass: XACML Reference Implementation

Today’s IT systems implement fine-grained access control mechanisms to protect a companies assets and to fulfill regulations such as Basel III, SoX, or HIPAA. In general, access control cannot fully capture all requirements. In particular, for exceptional situations it is hard to formulate access control policies taking all possible legitimate accesses into account. Exceptional Access Control is an approach for allowing users to override access control decisions in, e.g., emergency situations. Different approaches and techniques have been presented how to allow the user to override access control restrictions in a controlled way, e.g., Break (the) Glass. Break Glass Access Control allows users to override access control decision in a controlled manner.

This project contains an XACML PDP/PEP infrastructure supporting Break Glass Access Control.
