US Patent 10523701 Automated configuration of application firewalls

In a system for configuring a web application firewall, one or more parameters of the firewall are adjusted such that a test configured for exposing a vulnerability of an application protected by the application firewall is blocked by the firewall and another test configured to invoke functionality of the application but that does not expose or exploit any security vulnerability is not blocked by the firewall. A notification is provided to a user if such a firewall configuration is not found after a specified number of attempts.
