In most organizations, the only thought given to SELinux is remembering to turn it off when installing new systems. And yet as I respond to intrusion after intrusion on Linux systems, I know that most of them would never have happened had SELinux been properly deployed.
SELinux has been hampered by a suspicious pedigree (“It comes from the NSA—fear it!”) and a horrible initial roll-out (“This breaks everything—kill it with fire!”). But largely the issue is that the SELinux universe stands outside the normal Linux security model and troubleshooting strategy. Things break in mysterious ways when you enable SELinux, and the fixes are not obvious.
