Security Enhanced Linux (SELinux) is a security framework that allows and denies access to applications, files, etc. within a Linux system. For a full SELinux overview, see What is SELinux.

For this article, we will look at what happens when access to a desired file or application is denied. What messages will you see, where are these messages stored, and what does the information actually mean?
