Description:
MLS (Multi Level Security) variant of the SELinux policy
This is the reference policy for SE Linux built with MLS support. It allows giving data labels such as "Top Secret" and preventing such data from leaking to processes or files with lower classification. . It was developed for Common Criteria LSPP certification for RHEL. It will probably never be well supported in Debian and is only recommended for students who want to learn about the security features used by the military.
