Simplified Mandatory Access Control Kernel
"Smack is the Simplified Mandatory Access Control Kernel," Casey Schaufler said posting the third version of his patchest. He explained, "Smack implements mandatory access control (MAC) using labels attached to tasks and data containers, including files, SVIPC, and other tasks. Smack is a kernel based scheme that requires an absolute minimum of application support and a very small amount of configuration data."
Casey continued, "Smack is implemented as a clean LSM. It requires no external code changes and the patch modifies only the Kconfig and Makefile in the security directory. Smack uses extended attributes and provides a set of general mount options, borrowing technics used elsewhere. Smack uses netlabel for CIPSO labeling. Smack provides a pseudo-filesystem smackfs that is used for manipulation of system Smack attributes."
