Image scanning is the analysis of container images to identify vulnerabilities, misconfigurations, secrets, or unsafe components before deployment. It matters because container risk often enters through the image long before the workload ever runs.
What is Image Scanning?
Scanners inspect operating system packages, libraries, configuration, embedded credentials, and sometimes malware indicators. They help teams identify risky images early and improve patching, base image selection, and deployment policy.
What Image Scanning Commonly Supports
Common uses include CI/CD checks, registry governance, vulnerability management, and image approval workflows.
Image Scanning vs. Uninspected Image Deployment
Image scanning provides early visibility into risky content. Uninspected deployment allows vulnerable or unsafe images into later environments with less review.
Frequently Asked Questions
Why scan images?
Because vulnerabilities and unsafe defaults often live inside the image itself and are easier to fix before production.
Does scanning solve all container risk?
No. Runtime behavior, configuration, and authorization still matter too.
