# SELinux security

With the arrival of kernel version 2.6, a new security system was introduced to provide a security mechanism to support access control security policies.

This system is called **SELinux** (**S**ecurity **E**nhanced **Linux**) and was created by the **NSA** (**N**ational **S**ecurity **A**dministration) to implement a robust **M**andatory **A**ccess **C**ontrol (**MAC**) architecture in the Linux kernel subsystems.
This system is called **SELinux** (**S**ecurity **E**nhanced **Linux**) and was created by the **NSA** (**N**ational **S**ecurity **A**gency) to implement a robust **M**andatory **A**ccess **C**ontrol (**MAC**) architecture in the Linux kernel subsystems.

If, throughout your career, you have either disabled or ignored SELinux, this document will be a good introduction to this system. SELinux works to limit privileges or remove the risks associated with compromising a program or daemon.
