Frequently Asked Questions
What is container security?
It is the practice of protecting container images, the registry, the runtime and the host. It covers building minimal images, scanning for vulnerabilities and limiting what containers can do.
How do namespaces provide isolation?
Linux namespaces give each container its own view of processes, network and filesystem. Together with cgroups, which limit resources, they separate workloads, though they are not a full security boundary.
Why use minimal container images?
Smaller images contain fewer packages, so there is less to patch and fewer tools for attackers to use. This intermediate Codelivly room is free and covers building and scanning images.
