概要

Container security scanning detects vulnerabilities in image layers, dependencies, and configurations. Master tool integration, CI/CD pipeline scanning, and vulnerability management.

Container Security Scanningとは

Container Security Scanning is the process of analyzing container images for known vulnerabilities, misconfigurations, and policy violations. Scanning integrates into CI/CD pipelines to prevent vulnerable code from reaching production. Container vulnerabilities are a top attack vector. Organizations need experts to implement scanning, interpret results, and remediate issues. This skill is in high demand and commands premium salaries.

❓ よくある質問

▶What is container image scanning and why is it critical?
Scanning analyzes container images for known vulnerabilities in base OS, libraries, and dependencies. It prevents deploying vulnerable code to production.
▶What vulnerabilities does scanning detect?
Known CVEs (Common Vulnerabilities and Exposures) in packages, misconfigurations, hardcoded secrets, and policy violations.
▶What is the difference between image scanning and runtime scanning?
Image scanning analyzes static images before deployment. Runtime scanning monitors container behavior during execution, detecting zero-days and anomalies.
▶How do I integrate scanning into CI/CD?
Run scanners in pipeline stages: after build (pre-push), before deployment (pre-pull), and continuously in production. Fail builds if vulns exceed threshold.
▶What should I do if a vulnerability is found?
Patch the base image or dependency, rebuild the image, rescan to verify, and redeploy. For unfixable vulns, accept risk or use alternatives.
▶How do I manage false positives?
Most scanning tools provide ways to suppress known false positives. Document why; false positives erode trust in the tool and process.
▶What is Software Bill of Materials (SBOM) and why does it matter?
SBOM lists all components in a container (packages, versions). It enables tracking of vulnerability spread and compliance with regulations like NTIA guidelines.
