1.0 alpha 1, an implementation of the documented Sun Basic Security Module (BSM) Audit API and file format, as well as local extensions to support the Mac OS X and FreeBSD operating systems. Also included are command line tools for audit trail reduction and conversion to text, as well as documentation of the commands, file format, and APIs. This distribution is the foundation for the TrustedBSD Audit implementation, and is a pre-release. This is the first in a series of commits to introduce support for Common Criteria CAPP security event audit support. This software has been made possible through the generous contributions of Apple Computer, Inc., SPARTA, Inc., as well as members of the TrustedBSD Project, including Wayne Salamon <wsalamon> and Tom Rhodes <trhodes>. The original OpenBSM implementation was created by McAfee Research under contract to Apple Computer, Inc., as part of their CC CAPP security evaluation. Many thanks to: wsalamon, trhodes Obtained from: TrustedBSD Project
