Configuring FortiGate units for PCI DSS compliance

This chapter provides information about configuring your network and FortiGate unit to help you comply with PCI DSS requirements. There is also some description of other Fortinet products that can help you with PCI DSS compliance.

 

Introduction to PCI DSS

The primary source of information for your PCI DSS compliance program is the Payment Card Industry (PCI) Data Security Standard itself. Version 3.1 of the standard was published in April 2015. The following is a brief summary of PCI DSS.

 

What is PCI DSS?

The Payment Card Industry Data Security Standard (PCI DSS) sets data handling requirements for organizations that hold, process, or exchange cardholder information.

 

What is the Cardholder Data Environment

Throughout the PCI DSS requirements, there are references to the Cardholder Data Environment (CDE). The CDE is the computer environment wherein cardholder data is transferred, processed, or stored, and any networks or devices directly connected to that environment.

 

PCI DSS objectives and requirements

PCI DSS consists of 7 control objectives and 12 requirements.

This chapter describes how the FortiGate’s features can help your organization to be compliant with PCI DSS. Requirements that the FortiGate cannot enforce need to be met through organization policies with some means determined for auditing compliance.

Be sure to read the following wireless guidelines. Even if your organization does not use wireless networking, PCI DSS requires you to verify periodically that wireless networking has not been introduced into the CDE.

 

Wireless guidelines

While wired networks usually connect fixed known workstations, wireless networks are more dynamic, introducing a different set of security concerns.

Even if your organization does not use wireless networking, PCI DSS requires you to verify periodically that unauthorized wireless networking has not been introduced into the CDE. Wireless networking could be introduced quite casually by adding a wireless device to a PC on the CDE network.

For all PCI DSS networks, whether they use wireless technology or not, the following requirement applies:

• Test for the presence of wireless access points by using a wireless analyzer at least quarterly or deploying a wireless IDS/IPS to identify all wireless devices in use. (11.1)

If your organization uses wireless networking outside the CDE network and the firewall prevents communication with the CDE network, the wireless network is outside the PCI DSS scope, but the firewall configuration must meet PCI DSS requirements.

If your organization uses wireless networking inside the CDE network, the wireless network is within the PCI DSS

scope. For information about wireless network requirements, see Wireless network security on page 804.
