Question 1

What is container image scanning and why is it critical?

Accepted Answer

Scanning analyzes container images for known vulnerabilities in base OS, libraries, and dependencies. It prevents deploying vulnerable code to production.

Question 2

What vulnerabilities does scanning detect?

Accepted Answer

Known CVEs (Common Vulnerabilities and Exposures) in packages, misconfigurations, hardcoded secrets, and policy violations.

Question 3

What is the difference between image scanning and runtime scanning?

Accepted Answer

Image scanning analyzes static images before deployment. Runtime scanning monitors container behavior during execution, detecting zero-days and anomalies.

Question 4

How do I integrate scanning into CI/CD?

Accepted Answer

Run scanners in pipeline stages: after build (pre-push), before deployment (pre-pull), and continuously in production. Fail builds if vulns exceed threshold.

Question 5

What should I do if a vulnerability is found?

Accepted Answer

Patch the base image or dependency, rebuild the image, rescan to verify, and redeploy. For unfixable vulns, accept risk or use alternatives.

Question 6

How do I manage false positives?

Accepted Answer

Most scanning tools provide ways to suppress known false positives. Document why; false positives erode trust in the tool and process.

Question 7

What is Software Bill of Materials (SBOM) and why does it matter?

Accepted Answer

SBOM lists all components in a container (packages, versions). It enables tracking of vulnerability spread and compliance with regulations like NTIA guidelines.
