Security Enhanced Linux (SELinux) is a powerful, but often misunderstood security feature in Linux. Rather than try to figure out how SELinux can better secure a Linux system, some system administrators will just disable it.
To help you learn about (rather than just disable) SELinux, we recently published several episodes in a series of SELinux tutorial tech briefs. These tutorials give you hands-on ways of learning SELinux, along with pointers to excellent reference materials produced by people like Dan Walsh, David Egts, and Sean Huck.
Here are links to the first three episodes in the series. Just read them or set aside a bit of time to try them out. Then post some comments here to let us know what you think:
