The main purpose of performing firewall penetration testing is to prevent unauthorized access to the internal network from the internet. Depending on the type of firewall, most represent a traditional stateless firewall or a next-generation firewall, which remembers the state of all connections.

The success of any firewall penetration test depends on multiple factors. Making sure firewall policies and rules are configured properly will greatly reduce the attack success and prevent most unauthorized connection attempts.

Using security scanners such as Nmap, Hping and Netcat to enumerate and fingerprint the firewall will provide various information about the firewall, its access control lists and the state of its ports. Most decisions and actions a penetration tester will take will depend on these firewall responses.
