>I recognize, based on your other comment, that you are fairly new to the field(a whole decade, go you!).
I've been implementing secure, hardened UNIX and Linux probably longer than you've been alive. I just specifically worked on DoD TS+ systems for a decade.
The rest of your Gish gallop is nonsense. Linux also has capability based security ON TOP of all the other aspects of security, SELinux included.
>If you want to have a reasoned discussion about security
That's not possible with you. You instantly showed how little you know about security in general when you flouted your lack of SELinux knowledge, then you proceeded to Gish gallop and sealion because you've been called out.
Stop it.
