In accordance with the latest PCI scanning standard, Trustwave will be implementing changes in External Vulnerability PCI scans. These changes, mandated by the Payment Card Industry Security Standards Council, went into effect on Jan. 31, 2018.
PCI scans that passed previously may begin to fail due to changes in the scan assessment requirements. Scans may fail if our scanner cannot reach the scan targets identified in your Scan Setup. This means that you asked Trustwave to scan a target IP address that our scanner was ultimately unable to detect, and therefore unable to make a determination on overall security of the environment.
STEPS YOU SHOULD TAKE NOW:
You can update your Scan Setup now to prepare for the changes. Some things you can do to ensure that scan targets can be reached during a scan:
Check that an IP Address or Domain Name is correct in the Scan Setup and has not changed since you originally set up your scan.
Prevent active security measures from blocking targets. Permitting TrustKeeper scan traffic should only be done on active security devices (i.e. IDS/IPS, WAF, DDoS etc.) within or in front of the environment being scanned. Note that creating a rule on a firewall, which permits traffic to pass through, could reduce security defenses and cause additional scanning problems.
If available for download, install the Endpoint Protection Solution, which will monitor IP changes and help ensure you are always scanning the current IP address. It may also shorten your SAQ assessment.
Check out our help document for more information and graphics to help you through these steps.
IF SCANS BEGIN FAILING AFTER JAN. 31, 2018 YOU SHOULD:
View scan results identified as undetected hosts.
Update the Scan Setup to correct or remove the undetected hosts.
Review the steps listed above.
Rescan.
If a rescan continues to yield Undetected Hosts, then your IP address may be hidden by design for business security reasons. In this situation, you may raise a dispute via the Trustwave Dispute process.
