Container security

Container security components

Isolation. Each container operates independently of the others, thus preventing any potential tampering or data leakage between containers.

Image security. Container images are validated and scanned for vulnerabilities. It is important to use verified images from reputable sources and maintain a regular update schedule.

Runtime security. Container runtime security includes container and host OS orchestration, configuration management, use of least privilege principles, and network segmentation.

Best practices for container security

Principle of least privilege. Containers should be run with the least possible privileges to perform their functions to reduce the potential attack surface.

Regular updates and patches. Containers and their host systems should be updated regularly to address all known vulnerabilities.

Utilization of security policies. Implementing security policies, such as Pod Security Policies in Kubernetes, can keep containers running securely.

Monitoring and logging. Monitoring and logging container activity can help detect any anomalies or potential security threats.
