[seccomp](https://kubernetes.io/docs/tutorials/security/seccomp/) - "can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel."
[AppArmor](https://kubernetes.io/docs/tutorials/security/apparmor/) - "AppArmor is a Linux kernel security module that supplements the standard Linux user and group based permissions to confine programs to a limited set of resources. AppArmor can be configured for any application to reduce its potential attack surface and provide greater in-depth defense."
