2 SonicWall SonicOS Standard PCI Data Security Standard 1.1 Compliance: The following are the PCI Data Security Standard 1.1 controls which are applicable to SonicWall SonicOS Standard Edition. PCI DSS Requirement Establish firewall configuration standards that include: A formal process for approving and testing all external network connections and changes to the firewall configuration. N/A SonicWALL Administrator Guide should include this as a Best Practice. PCI DSS Requirement Establish firewall configuration standards that include: Requirements for a firewall at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone. N/A Verify that there is a firewall installed between the DMZ and internal network in all cases. PCI DSS Requirement Establish firewall configuration standards that include: Description of groups, roles, and responsibilities for logical management of network components. 1. Login to Sonicwall firewall. 2. Verify and ensure that the source and destination IP s reflect to the degree possible logical combinations of groups. For example, in the screenshot below OPT, LAN and WAN are examples of logical IP groups. 1

3 Verify grouping of IP addresses whenever possible. 2

4 PCI DSS Requirement Establish firewall configuration standards that include: Justification and documentation for any available protocols besides hypertext transfer protocol (HTTP), and secure sockets layer (SSL), secure shell (SSH), and virtual private network (VPN). 1. Login to the SonicWALL firewall. 2. Select the Firewall menu, and select the Access Rules item. 3> Documentation for justification must exist for any services that are allowed to the internal network besides HTTP, SSH, SSL and VPN. 3

7 5. The new rule will appear in the Access Rules list as seen below. 6

8 SonicWALL's default policy on its security devices is to have a "denial-all" policy to everything internal to the network. 7

9 PCI DSS Requirement Build a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data, including any connections from wireless networks. This firewall configuration should include the following: Restricting inbound Internet traffic to Internet protocol (IP) addresses within the DMZ (ingress filters). N/A Ensure that any of the IP s mentioned above (i.e. wireless and cardholder systems) are adequately protected within the network behind firewall rule-sets. PCI DSS Requirement Build a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data, including any connections from wireless networks. This firewall configuration should include the following: Not allowing internal addresses to pass from the Internet into the DMZ. N/A Ensure that any of the IP s mentioned above (i.e. wireless and cardholder systems) are adequately protected within the network behind firewall rule-sets. PCI DSS Requirement Build a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data, including any connections from wireless networks. This firewall configuration should include the following: Implementing stateful inspection, also known as dynamic packet filtering (that is, only established connections are allowed into the network). N/A Ensure that any of the IP s mentioned above (i.e. wireless and cardholder systems) are adequately protected within the network behind firewall rule-sets. 8

10 PCI DSS Requirement Build a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data, including any connections from wireless networks. This firewall configuration should include the following: Placing the database in an internal network zone, segregated from the DMZ. N/A Ensure that any of the IP s mentioned above for the database are adequately protected within the network behind firewall rule-sets. PCI DSS Requirement Build a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data, including any connections from wireless networks. This firewall configuration should include the following: Restricting inbound and outbound traffic to that which is necessary for the cardholder data environment.
