ASV Attestations

If you requested an ASV Attestation of Scan Compliance (AoSC) in Step 2 of the wizard when you created your scan job, then there are several requirements you must satisfy before the attestation can be issued.  Use the following steps after the scan completes to fulfill these requirements.

 

  1. Go to the Results tab and choose the PCI Attestation report type from the drop-down menu.



  2. Click on the Create Report button beside the desired data set.



  3. For each row of the checklist which has a red X in the Status column, follow the instructions in the Instructions column. Click on the wrench icon in the Actions column or the appropriate hyperlink in the Instructions column to complete each required task. See the following sections for additional information.

 

Targets Running No Services

If the scan detected one or more targets with no listening services, you must confirm that this is the correct result, and not indicative of a scan malfunction.  If this is the correct result, click on the action button beside All targets successfully scanned or click on the attest that the target runs no listening services hyperlink, check the box, and submit the form.

 

 

Scan Scope

The PCI DSS requires scanning of all externally accessible system components owned or utilized by the scan customer that are part of the cardholder data environment or may provide access to the cardholder data environment. Although proper scoping is the responsibility of the scan customer, the ASV is required to report any potential scoping discrepancies and confirm with the customer that they are out of scope. If potential scoping discrepancies are found, click on the action button beside Scan included all targets which belong in scope or on the attest that they are out of scope hyperlink. This displays a table containing information about each scoping discrepancy.  If each of the listed components are truly out of scope, check the box and submit the form.

 


Vulnerability Disputes

If vulnerabilities which cause PCI failure are detected, the customer may either remediate the vulnerabilities and run the scan again, or else dispute the failing vulnerability findings.  A vulnerability may be disputed for the following reasons:

  1. False positive – You may dispute the vulnerability if you believe the vulnerability does not actually exist on the system.

  2. Compensating controls – You may dispute the vulnerability if there is an acceptable compensating control in place which eliminates the risk of the vulnerability.

  3. Incorrect CVSS score – You may dispute the vulnerability if you believe the CVSS score is incorrect.


If you choose to dispute the findings, follow these steps:

  1. From the Post-scan ASV Attestations grid, click on the action button beside All scan results pass or the dispute the results hyperlink.

  2. Click on the New Dispute tab.



  3. Click on the Dispute button (plus icon) beside the vulnerability that you wish to dispute, or check the rows corresponding to the vulnerabilities you wish to dispute and click on Dispute Selected. If the vulnerability you are looking for does not appear on the first page, use the pager buttons at the top and bottom of the grid to page through the vulnerabilities, or enter terms into the filter boxes at the top of the columns to search for the vulnerability.




  4. Complete and submit the Create Dispute form. Be sure to provide a detailed explanation and/or evidence that supports your claim that the vulnerability should not cause PCI failure. For example, if the vulnerability finding is a false positive resulting from backported fixes in Linux packages, you may want to include a screen shot which shows the installed package version.




  5. Click on the OK button to attest that the submitted evidence is accurate and complete. That will result in a message informing you that the dispute has been submitted to the ASV staff.



  6. When the ASV staff has made a decision regarding the dispute, you will receive an e-mail notification informing you of the result. The result will be one of the following:


If you wish to check the status or modify a dispute you’ve already submitted, follow these steps:

  2. Click on the Existing Disputes tab. The status of each existing dispute will be one of the following:

  1. Find the desired dispute on the grid. If it doesn’t appear on the first page, use the pager bar at the top or bottom of the grid to page through the disputes, or use the filter boxes at the top of each column to search for the desired dispute.

  2. To view the activity regarding a dispute, click on the Log button (notebook icon) under the Actions column for the desired dispute.

  3. For pending disputes only: Click on the Edit button (pencil icon) to open a form allowing you to modify the dispute or upload additional evidence. This form is similar to the form you originally used to create the dispute. Submitting this form will change the dispute status back to Open.

Customer Identity

All ASV scans require certain information about the scan customer in order to complete the Attestation of Scan Compliance. Click on the action button beside Identity Information Provided or click on the Provide the customer identity information hyperlink to enter this information.

 

 

Special Notes

The ASV Program Guide specifies that certain findings be documented in the ASV Executive report as special notes. These are findings which don’t necessarily cause failure, but still require a declaration from the customer to assure the ASV that they do not expose the cardholder data environment to any unnecessary risk. To view the special notes and enter declarations:

 

  1. Click on the action button beside Declarations provided for special notes or on the corresponding hyperlink.



  2. Click on the Edit button (pencil icon) beside any of the special notes which has a red X. This brings up a dialog providing further instructions and a form to enter the declaration.



  3. Choose the appropriate option from the drop-down menu and enter a declaration which satisfies the instructions. Then click on the Submit button.

  4. Repeat the previous two steps until all rows in the special notes grid have a green check mark.



  5. Click the Close button.
