Users themselves cannot modify permissions. For this reason, MAC is rarely fully implemented on production systems outside of highly secure environments. MAC is normally implemented as a rule based access control system where users and resources have labels and the operating system makes access control decisions by comparing those labels. The most common example of an operating system implementing MAC is security-enhanced Linux, or SELinux, a Linux kernel security module developed by the US National Security Agency in the 1990s and included in some Linux distributions, including Red Hat Enterprise Linux, CentOS, and Fedora.
