90-Day Image Age

No violationsstackroxlowbuilddeploy

Alert on deployments with images that haven't been updated in 90 days

Rationale: Base images are updated frequently with bug fixes and vulnerability patches. Image age exceeding 90 days may indicate a higher risk of vulnerabilities existing in the image.
Remediation: Rebuild your image, push a new minor version (with a new immutable tag), and update your service to use it.
