SELinux

Oh by the way – here is a small insight on SELinux.

SELinux is Security Enhanced Linux !! It basically provides a strong, flexible mandatory access control architecture into the major subsystems of the kernel. The system provides a mechanism to enforce the separation of information based on confidentiality and integrity requirements.

SELinux was originally developed as a research prototype of the Linux® kernel and a number of utilities with enhanced security functionality designed to demonstrate the value of mandatory access controls to the Linux community and how such controls could be added to Linux. Today SELinux is integrated into the mainline Linux 2.6 kernel series and several Linux distributions.

You can download it from http://www.nsa.gov/selinux/ or you can use a distribution that already includes support for SELinux.
