Container and Kubernetes Security

Scan images for vulnerabilities, configure Pod Security Standards, and use network policies in Kubernetes.

Container Security Overview

Containers share the host kernel, making them less isolated than VMs. Container security spans: image hygiene (no vulnerable packages), runtime protection (detecting abnormal behavior), network policy (restricting pod communication), and RBAC configuration.

Image Scanning with Trivy

Trivy scans container images for OS package CVEs, application dependency vulnerabilities, misconfigurations, and secrets. Integrate into CI/CD to block images with critical vulnerabilities before they reach production.
