Security-Enhanced Linux is a security architecture integrated into the asterisk Nix kernel, so it could be Unix, Linux, that provides a mechanism for supporting access control security policies. Some of the key features are SELinux support of mandatory access control, enforcing MAC policies that restrict users and processes to the minimum privileges necessary to perform their tasks. So unlike discretionary access control, where users can change permissions or they can create shares and allow access to their own files, MAC policies are centrally managed and cannot be altered by regular users. With SELinux, you get fine-grained access control. So SELinux allows for detailed and granular control over access to files, processes, and Linux system resources, like configuration files.
