Extending access control models with break-glass
Access control models are usually static, i. e., permissions are granted based on a policy that only changes seldom. Especially for scenarios in health care and disaster management, a more flexible support of access control, i. e., the underlying policy, is needed. Break-glass is one approach for such a flexible support of policies which helps to prevent system stagnation that could harm lives or otherwise result in losses. Today, breakglass techniques are usually added on top of standard access control solutions in an ad-hoc manner and, therefore, lack an integration into the underlying access control paradigm and the systems ’ access control enforcement architecture. We present an approach for integrating, in a fine-grained manner, break-glass strategies into standard access control models and their accompanying enforcement architecture. This integration provides means for specifying break-glass policies precisely and supporting model-driven development techniques based on such policies
