Examples of MAC
• Linux enhancements
- RSBAC by the Adamantix project
- SE by the NSA
-LIDS
• eTrust CA-ACF2 by CA
• Multics-based Honeywell
•SCOMP
• Pump
• Purple Penelope
When most people talk about the types of MAC, they refer to models such as Bell-LaPadula Policy
and Biba. Implementation examples are Linux enhancements, such as RSBAC by the Adamantix
project; SE (Security Enhanced) Linux by the NSA (SE Linux currently supports 30 object classes
and 122 object permissions (rules); Flask, which has been incorporated into SE; or LIDS. Each of
these must be examined in terms of their ability to allow information flow to/from its associated
object class.
The following are additional examples:
• Computer Associate's eTrust CA-ACF2 Security for z/OS and OS/390
• Multics-based Honeywell computer
• SCOMP (Secure Communications Processor)
• Pump (developed by the US Naval Research Laboratory)
• Purple Penelope (An NT workstation MLS wrapper from the British Defense Evaluation and
Research Agency)
