What is SELinux? - SELinux Commands - Chris Titus Tech This video answers the questions what is SELinux and explains the various SELinux commands you should know. It breaks down the 3 modes of SELinux. 1. Enforcing 2. Permissive 3. Disabled I also go into why people change SELinux modes and which distribution have SELinux Enforcing by default. SELinux basically breaks down all processes into labels and assigns them independent privileges based on the SELinux label. Commands: Check SELinux status # sestatus OR # getenforce Temporarily enforce SELinux # setenforce 1 Permanently change SELinux # nano /etc/selinux/config -CHANGE- SELinux=disabled Check if it is blocking anything # ausearch -m AVC,USER_AVC -ts recent Keeping SELinux enforcing or permissive Many companies do not take the time to make their application SELinux compatible and if you leave it enabled you will probably need to do ome additional troubleshooting with the setroubleshoot command. Also, I highly recommend reading the System Administrator Guide to SELinux from opensource.com if you want to use it. https://opensource.com/article/18/7/sysadmin-guide-selinux

Micha-
Can you do the same video for AppArmor? I use Ubuntu on the server and that comes with AppArmor by default. I never needed to mess with it but some basic managing video-info would be nice.

Thank you, very informative. I need to learn some SELINUX and this was straight to the point and was short enough to not feel overwhelmed.
