What it means
Approved Scanning Vendor scans provide externally performed vulnerability scanning for applicable internet-facing systems under PCI scanning rules, with defined scope, evidence, dispute, remediation, and passing criteria.
Why it matters
A passing scan can be misleading if assets are missing, scan interference exists, vulnerabilities are disputed without evidence, or remediation is not sustained between quarters.
Practical focus
- Maintain an accurate inventory of external IP addresses, domains, services, cloud endpoints, and changes that affect scan scope.
- Prepare systems for legitimate scanning without weakening controls or filtering results, and investigate every failure.
- Preserve scan attestations, scope, results, disputes, remediation, rescans, and change-triggered scans.
- Preserve this evidence: Retain approved definitions, decisions, operating records, exceptions, test results, and change history that show how Approved Scanning Vendor Scans works over time.
- Exercise this failure scenario: A newly exposed cloud endpoint is omitted from the ASV scope and remains vulnerable while the organization reports a passing scan.
Common mistakes
- Using Approved Scanning Vendor Scans as a label without defining its scope, owner, decision criteria, and expected evidence.
- Treating a diagram, policy, tool screen, or meeting as proof that Approved Scanning Vendor Scans operates consistently in real work.
- Optimizing for a one-time review while leaving normal operating decisions, exceptions, and handoffs uncontrolled.
- Testing only the expected path and never rehearsing this failure condition: A newly exposed cloud endpoint is omitted from the ASV scope and remains vulnerable while the organization reports a passing scan.
