CS0-003 Vulnerability Management Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Burp Suite

  Why it's wrong here

  Burp Suite is a web application security testing proxy that intercepts HTTP/S traffic to map attack surfaces and manually or automatically test for vulnerabilities such as SQL injection, XSS, and authentication bypass. It does not parse container image layers, inspect OS package inventories, or query CVE databases, and it lacks integration with container registries and CI/CD pipelines for image-level assurance. Therefore, it is fundamentally misapplied to a container security scanning initiative.

• ✓

  Trivy

  Why this is correct

  Trivy is an open-source, fast, and comprehensive vulnerability scanner designed specifically for container images. It scans both OS packages (e.g., Alpine, Debian) and application dependencies (e.g., Python, Node.js) by comparing against a continuously updated CVE database, and it can be easily embedded into CI/CD pipelines with a simple CLI without requiring a separate server. Its low false-positive rate and support for multiple input formats (e.g., Docker, Podman, OCI) make it the most straightforward and effective choice among these options for the security team's container scanning need.

• ✗

  OpenSCAP

  Why it's wrong here

  OpenSCAP is a security compliance framework that evaluates hosts against SCAP-backed policy baselines such as CIS benchmarks, checking system configuration, installed packages, and file permissions. While it can detect some vulnerable packages on a running host, it does not decompose container image layers, inspect image manifests, or interact with container registries, and it cannot provide vulnerability intelligence specific to the container runtime or image build process. Consequently, it is not a container-native scanning tool and is inappropriate for this task.

• ✓

  Clair

  Why this is correct

  Clair is an open-source project originally from CoreOS that performs static analysis of security vulnerabilities in container images. It ingests images from registries, breaks them into layers, and correlates installed OS packages with CVE data via a PostgreSQL-backed API, enabling tools like Quay or custom queries to retrieve results. As a registry-integrated scanner, it is a valid option for continuous vulnerability assessment, though it requires more operational overhead—namely a database and backend services—compared to more modern single-binary scanners.

• ✓

  Snyk

  Why this is correct

  Snyk is a developer-first security platform that offers container scanning for known vulnerabilities, license compliance, and configuration drift, with robust integrations into IDE plugins, Git repositories, and CI/CD systems. Unlike purely image-layer scanners, Snyk also performs deep dependency analysis and provides actionable fix advice, patching recommendations, and continuous monitoring through both free and commercial tiers. It is a correct tool for container security scanning, particularly when the team wants developer-friendly policy enforcement in addition to CVE detection.
