Container Security

Container security across build to runtime is achieved by integrating image scanning with Trivy, runtime threat detection with Falco, and image signing with Notary, enforced by Kubernetes security policies and admission controllers.

Scanning Docker images for vulnerabilities is best handled by using Trivy to detect vulnerabilities and misconfigurations in your container images, ensuring critical flaws are caught before registry push or Kubernetes deployment.

Monitoring Kubernetes container activity for suspicious behavior is possible using Falco, which provides runtime threat detection to alert on policy violations and anomalous processes during container operation.

Image authenticity is enforced using Notary for image signing, ensuring the integrity of container images before they are admitted to the Kubernetes cluster via configured admission controllers.

To implement container security policies, Kubernetes is required as the foundational dependency to enforce security best practices and compliance through Pod Security Policies and admission controllers.

Admission controllers are used for container security in Kubernetes to programmatically enforce security best practices, preventing vulnerable or unsigned images from being deployed into the runtime environment.
