A Brief Introduction to Multi-Category Security (MCS) (LiveJournal)
James Morris has written an
introduction to MCS on LiveJournal. "
MCS is something we've been working on to help make SELinux more user-oriented, as well as adapt some of the Multi-Level Security (MLS) infrastructure for more general use. An important aspect of SELinux is that it implements Mandatory Access Control (MAC), where security policy is managed by a system or security administrator and is not overridable by users or applications. MAC is important for dealing with security threats arising from software flaws, malware, user error and some classes of malicious users."
