Landlock merged in mainline for Linux 5.13
I&#x27;m completely lost with Linux sandboxing and security tools , AFAIK there is<p>- cgroups<p>- cgroupsV2<p>- namespaces<p>- AppArmor<p>- SELinux<p>- LSM<p>- seccomp<p>- seccomp-bpf<p>- eBPF (I know it&#x27;s not a security thing per se, but it&#x27;s a building block for sandboxes)<p>- and now landlock.<p>Could anyone here give me an ELI5 about which one does what? (also which one you&#x27;re supposed to use together, and which are competitors to each others)<p>Or maybe give me some pointer to a good introduction to these?
