Interview Question

How would you secure container runtimes (e.g., Docker, containerd) in production environments?

Key Points to Cover
  • Run containers as non-root with least privileges
  • Use seccomp, AppArmor, SELinux profiles for sandboxing
  • Scan base images and enforce signed images
  • Limit syscalls and kernel capabilities
  • Enable runtime monitoring (Falco, eBPF)
