Correct enforcement of authorization policies is a difficult task, especially for multi-threaded software. Even in carefully-reviewed code, unauthorized access may be possible in subtle corner cases. We introduce Transactional Memory Introspection (TMI), a novel reference monitor architecture that builds on Software Transactional Memory--a new, attractive alternative for writing correct, multi-threaded software.
