PCI DSS Firewall Security Audit Guidelines

Download free PCI DSS Firewall Security Guidelines:
- The PCI DSS requires a firewall that provides stateful inspection, also known as dynamic packet filtering.
- Stateful inspection firewalls offer strong security along with good performance and transparency to end users, unlike the packet filtering and proxy firewalls.
- Document your dataflow in order to aid the system and security administrators in configuring the firewall with the proper rule set.
- Disable or remove all unneeded ports, protocols, and services not required for business purposes.
- Deny all traffic into and out of the firewall that is not required for business purposes.
- Your firewalls and routers must have documented configuration standards and the rule sets of each should be reviewed at least quarterly.
