21 Docker Security Best Practices – Deamon, Image & Container

Docker is a popular containerization platform that enhances the security of workloads by isolating software and its dependencies into self-contained units. However, improper hardening can pose new security risks. To ensure Docker security, follow best practices for Docker daemon security, image security, and container security. These include not exposing unnecessary ports, using minimal base images, setting up container resource quotas, and more. Regularly updating Docker, scanning images for vulnerabilities, and linting Dockerfiles are also crucial steps in maintaining good security posture.
