There's an insane amount of tooling with varying degrees of overlap. You've got SELinux, BPF, seccomp, AppArmor as different approaches to security. Each of these takes quite a bit of dedicated time to master and most of them have lots of nuance & there can be overlap depending on what you're trying to secure. In a work environment, I'd typically outsource this to security engineers/experts OR spend my time learning those things for what I need them for - knowing the tools are out there are sufficient starting points for research when I need that knowledge.
None of this applies to maintaining my development machine. You might want to revisit your gate keeping.
Nah. I agree with the other guy. AppArmour takes some time to learn and isn't super mainstream yet. At least it's a step forward from SELinux, but it still feels uncooked and adhoc to me.
