Clair
An open-source project for the static analysis of vulnerabilities in application containers. Clair v4.x ingests vulnerability metadata from various sources and allows clients to query for vulnerabilities present in an image with improved performance and database management.
Why it stands out: Clair is a foundational tool often integrated into private container registries and custom security platforms for its powerful API-driven approach.
Frequently asked questions
What's the difference between a vulnerability scanner and a SAST tool?
A vulnerability scanner primarily identifies known security flaws (CVEs) in third-party dependencies, container base images, and system configurations. A Static Application Security Testing (SAST) tool analyzes your first-party source code to find potential security weaknesses and coding errors, like SQL injection or buffer overflows, before the code is compiled.
How do I integrate a vulnerability scanner into a CI/CD pipeline?
Most modern scanners can be run as a step in your CI/CD pipeline (e.g., in GitHub Actions, Jenkins, or GitLab CI). A common practice is to add a step after the build phase to scan the resulting container image or dependencies. You can configure the pipeline to fail the build if vulnerabilities exceeding a certain severity threshold (e.g., 'Critical' or 'High') are found.
What is an SBOM and how does it relate to vulnerability scanning?
An SBOM, or Software Bill of Materials, is a formal, machine-readable inventory of all the components, libraries, and dependencies included in a piece of software. Vulnerability scanners can use an SBOM as a manifest to quickly and accurately identify all software components and cross-reference them against databases of known vulnerabilities, improving the speed and reliability of the scan.
Should I use an open-source or a commercial vulnerability scanner?
The choice depends on your needs. Open-source tools like Trivy and Grype are powerful, flexible, and excellent for integration into CI/CD pipelines, especially for container scanning. Commercial tools like Snyk or Wiz often provide a more polished user experience, broader feature sets (SAST, IaC, CSPM), enterprise-grade support, and advanced risk prioritization capabilities that are valuable for larger organizations.
