How do I protect Docker containers from privilege escalation attacks?

Asked on Sep 17, 2025

Answer

To protect Docker containers from privilege escalation attacks, you should implement strict security configurations and follow best practices to minimize risks.

<!-- BEGIN COPY / PASTE -->
    docker run --security-opt no-new-privileges --cap-drop=ALL --cap-add=NET_BIND_SERVICE --user nobody:nogroup ...
    <!-- END COPY / PASTE -->

Additional Comment:

Use the --security-opt no-new-privileges option to prevent processes from gaining additional privileges.
Drop all unnecessary capabilities with --cap-drop=ALL and add only the specific ones needed using --cap-add.
Run containers as a non-root user by specifying --user to limit the impact of a potential breach.
Regularly update Docker and its components to patch known vulnerabilities.
