Interview question · Cloud, Container & AI Infrastructure Security

What are the realistic ways a workload escapes its container, and which controls close each path?

Most escapes are not clever kernel exploits. They are configuration that handed the container the host: a privileged flag, a mounted socket, a host path or a shared namespace.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A pod in your cluster is compromised through an application vulnerability, and you need to know whether the attacker can reach the node.

  1. What isolates the container?
  2. Which configurations give escape without any bug?
  3. What about kernel bugs?
  4. What about runtime bugs?
  5. What should you do in this incident?
  6. How would you assess and reduce escape risk?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
