When you need to run Linux in an especially secure environment, SELinux is the answer. But it takes some know-how to get the hypersecure Linux version up and running.
Twenty years ago, when it became apparent how important Linux would become, the U.S. National Security Agency created a mandatory access control (MAC) architecture for Linux. As in other realms, security is always important, but sometimes it’s especially important. From its creation and extending to today, Security-Enhanced Linux (SELinux) has blocked tampering threats and prevented attempts to bypass application security.
