SELinux and modification

Like AppArmor, Security-Enhanced Linux (SELinux) is a way to introduce mandatory access controls into Linux, only it has a couple of key differences:

• It's more widely used and loathed than AppArmor
• It's primarily used on Red Hat-based distributions

If you're in the enterprise world, or thinking of going there, SELinux is a great tool to add to your tool belt.

You might recall that we've already touched on SELinux previously, making a couple of small changes to allow things like SSH to run on different ports; here, we're exploring it further.

For this section, we're going to use our CentOS VM.

SSH to your CentOS VM, forwarding 8080 as you do:
