Living with SELinux
Security Enhanced Linux, is still disabled in many cases due to fact that most people do not take the time to understand how to work with SELinux. While in it’s current state SELinux has become very easy to manage and increases security on the overall system and most applications. The segregation of compartments increases the overall security impact and changes the way we can secure a system. In current versions of Enterprise Linux most common applications are predefined in SELinux policies and can be adjusted, by using the right booleans, however other applications can be added easily with the integrated tools, allowing you to run any custom application with SELinux enabled for that application. The presentation explains what SELinux is, how it works, and some practical
use cases. It will briefly show how to implement the predefined policies and how to generate custom policies.
