Linux security: Manipulating SELinux policies with Booleans
This tutorial examines the flexibility that Booleans offer SELinux and how to make use of them.
Security-Enhanced Linux, better known as SELinux, has been around for a while now—and for good reason. Originally developed by the National Security Agency, it has been a part of the open source community since 2000 and a part of the Linux kernel since 2003. SELinux helps administrators keep tabs on how different parts of a Linux system can perform actions with fine-grain controls.
