DESCRIPTIONThe policy module implements a testing facility for the MAC framework. Among other things, will try to catch corrupt labels the system is attempting to destroy and drop to the debugger. Additionally, a set of statistics regarding the number of times various MAC framework entry points have been called is stored in the security.mac.test sysctl(8) tree.
Label FormatNo labels are defined for .
HISTORYThe policy module first appeared in Fx 5.0 and was developed by the TrustedBSD Project.
AUTHORSThis software was contributed to the Fx Project by Network Associates Labs, the Security Research Division of Network Associates Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS'' ) as part of the DARPA CHATS research program.
BUGSSee mac(9) concerning appropriateness for production use. The TrustedBSD MAC Framework is considered experimental in Fx .
While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by entry point checks. As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user.
