Examine firewall and router configurations to verify that connections are restricted between publicly accessible servers and components storing cardholder data, as follows:


PCI-1.3.4: Determine that the firewall performs stateful inspection. Only established connections should be allowed in, and only if they are associated with a previously established session.



Testing Procedures

Engage a port scanner such as [NMAP] on all TCP and UDP ports with “syn reset” or ”syn ack” bits set.

  • A response means packets are allowed through even if they are not part of a previously established session.

Testing Frequency

Quarterly scans for all production systems currently in use or new systems prior to production deployment.

Evidence Archive Location

Insert hyperlink or location of evidence archive.

Control Stewards Process Narrative

Provide control steward commentary indicating the formal methodology in place.


Control Steward – Jane Manager

Process Illustration

Replace this test by inserting a process diagram, flowchart or other visual representation to illustrate the process narrative as necessary. Include a brief description of the process illustration.

Control Status and Auditors Commentary

The control is effective.


File:Greenlock.jpg

Status is acceptable.

Control Exception Commentary

Status is acceptable.

Remediation Plan

Remediation is not required at this time.
