- Static Analysis Security Testing (SAST) inspects container images for vulnerabilities and misconfigurations.
- It analyzes the container's code, configurations, and dependencies without running the container.
- Dockerfile: Checks for insecure instructions like using
latest tags or running as root.
- Base Images: Scans the operating system and libraries in the base image for vulnerabilities.
- Dependencies: Analyzes libraries and tools installed inside the container for outdated or insecure versions.
- Exposed Ports: Identifies unnecessarily exposed ports that could widen the attack surface.
- Secrets and Sensitive Data: Detects hardcoded secrets like API keys or passwords inside container layers.
- Trivy: Open-source tool that scans container images for vulnerabilities.
- Docker Scan: Built-in Docker CLI tool powered by Snyk for security analysis.
- Anchore: Comprehensive container scanning platform.
- Clair: Static vulnerability analysis tool for container images.
- Identifies vulnerabilities before deployment, reducing risks in production.
- Ensures compliance with security standards and best practices.
- Saves time and effort by catching issues early in the development lifecycle.
