Description:

SE(Security Enhanced) Linux is a security feature in the Linux kernel. It is enabled by default in distributions like Fedora and RedHat Enterprise Linux. SELinux provides more fine grained access control compared to traditional file permissions. A centralized policy determines which software can access what resources.

One of the main benefit of SELinux is that it gives you the ability to secure processes from each other within the system. For example, if you have a web server on the Internet which is also serving Email and DNS then you would not want a vulnerability in the web server process allowing the attacker access to corrupt your DNS server.

The main drawback is a litte cost in performance see eg

No. This will not happen. This is a large burden, requiring recompiling of many core packages for selinux support, providing policies, and would represent a major shift in the distro.
