Strictly Confined MicroK8s
In summary, it is a snap confinement level that provides complete isolation, up to a minimal access level that’s always deemed safe. Strictly confined snaps can not access files, networks, processes, or any other system resource without requesting specific access. Strict confinement uses security features of the Linux kernel, including AppArmor, seccomp, and namespaces to prevent applications and services from accessing the wider system.
