How can I secure Docker containers from privilege abuse?
Asked on Oct 03, 2025
Answer
To secure Docker containers from privilege abuse, you should minimize the privileges granted to containers and use Docker's security features effectively.
<!-- BEGIN COPY / PASTE -->
docker run --cap-drop=ALL --cap-add=NET_BIND_SERVICE --security-opt=no-new-privileges myimage
<!-- END COPY / PASTE -->Additional Comment:
- Use
--cap-drop=ALLto remove all capabilities, then selectively add only those necessary. - The
--security-opt=no-new-privilegesoption prevents processes from gaining additional privileges. - Avoid running containers as the root user; use a non-root user whenever possible.
- Regularly update Docker and your container images to patch known vulnerabilities.
