Rotate Between_3 SELinux Modes

The goal of this lab is to change between the three SELinux modes: enforcing, permissive, and disabled. You will begin with the enforcing mode being active first, and then you will need to switch to permissive mode. After that, you will switch to disabled mode and then back to enforcing mode again. When rotating between modes, you can do a rotation of modes for the current session or a permanent mode change. An example of a permanent change would be when you go into a configuration file and you write permissive instead of enforcing or instead of permissive you write disabled. The goal is to set SELinux to permissive mode both for persistent reboot and for the session without a system reboot. After that, set the mode to disabled for both the persistent reboot and for the session with a system reboot. Lastly, change back to enforcing mode for both the reboot and the session.
