What are the security considerations when using Docker?

The security considerations when using Docker are ensuring proper image sourcing by using trusted repositories, regularly scanning images for vulnerabilities, and avoiding running containers as root. Impose resource limits to avoid overutilization of containers and isolate sensitive data with secrets management. Securing networks is relevant, too: limit communication between containers to only those that are necessary and activate firewalls. Keep the Docker daemon and the containers updated on recently released security patches. Switch namespace isolation on and avoid operating in privileged mode whenever possible. Monitor containers against suspect activities by using security tools such as Docker Bench or third-party solutions. Configure access controls correctly and limit unauthorized access to Docker resources.
