Unlike SELinux and AppArmor, Smack has never been supported by a major Linux distribution. The greatest barriers to distribution support have been that only one "major" security module can be used at a time and that there has been no example of a Smack rule set to use as a basis for a distribution's policy. In this talk Casey Schaufler, the author of Smack, will describe a new effort to create a reference set of Smack rules and apply it to a major Linux distribution. The talk starts with a description of how Smack rules work and how they differ from SELinux and AppArmor policy. It moves on to cover the threats being addressed and how a "three domain" approach provides the required protection.
