PCI Requirement 11.2.2 – Perform Quarterly External Vulnerability Scans via an Approved Scanning Vendor

What is an ASV?

To comply with PCI Requirement 11.2.2, you must use a PCI SSC Approved Scanning Vendor (ASV). An ASV is defined as, “An organization with a set of security services and tools (‘ASV scan solution’) to conduct external vulnerability scanning services to validate adherence with the external scanning requirements of PCI DSS Requirement 11.2.2. The scanning vendor’s ASV scan solution is tested and approved by PCI SSC before an ASV is added to PCI SSC’s List of Approved Scanning Vendors.”

The second component of PCI Requirement 11.2.2 is quarterly external vulnerability scans. External networks are at such a great risk of being compromised, which is why quarterly external vulnerability scans, and rescans as needed, are vital to scanning programs.

During an assessment, your assessor will follow these testing procedures:

  • Examine your four most recent quarters of external vulnerability scans and verify that four quarterly external vulnerability scans occurred in the most recent 12-month period.
  • Review the results of each quarterly scan and rescan to verify that the ASV Program Guide requirements for a passing scan have been met.
  • Review the scan reports to verify that the scans were completed by an ASV.

PCI Requirement 11.2.2 is very similar in nature to PCI Requirement 11.2.1, but PCI Requirement 11.2.2 requires that you perform external vulnerability scans. Where PCI Requirement 11.2.1 allowed an internal qualified resource to perform that activity, PCI Requirement 11.2.2 is a little different there: you must use an ASV to perform that activity on your behalf. KirkpatrickPrice would be happy to help you with that service, and we provide that service for many of our clients. There are many other organizations that can do that as well.

Nevertheless, effectively anything with the CVSS sore of 4.0 or higher needs to be addressed within that quarterly timeframe. Understand that a lot of organizations might miss a scan or forget to do it for whatever reason, and then ask us to help them define a compensating control. We’ll talk about compensating controls later, but understand that this is one of those controls that is very difficult to define, especially defining a compensating control for a failure in your program. So, understand that it is different if you identify vulnerabilities versus forgetting to scan—those are really two different conversations. Your assessor in both of these cases, for PCI Requirement 11.2.1 and PCI Requirement 11.2.2, is going to be asking for evidence of your quarterly scan and then any remediation scans that you have done to demonstrate that any vulnerabilities identified have been fixed.
