If youâre reading this site regularly, youâd probably agree how containers are starting to change the way we perceive the application stack. However, major questions still linger around container security.

The version 0.8 release of CoreOSâs rkt container runtime (which everyone calls âRocketâ) incorporates Clear Containers to provide hardware-assisted security.

Where VMs inherently provide good isolation â as the attack surface on hypervisors is really small â containers still rely on borrowed security. They depend on underlying technologies on which they are built and, of course, careful configuration by humans, as well. You can see where the potential issues might be.
