Advanced security devices use application intelligence. Products with this capability understand the correct flow of application data, and they recognize and reject traffic that might indicate a threat to the application or to its host system.
Application intelligence provides and enforces application layer security. A product with this capability, such as F5 BIG-IP® Application Security Manager, is often termed an application layer firewall. It protects applications from malicious attacks while ensuring application performance. By enforcing granular security policies, it protects Web applications and confidential information from both random and targeted application security attacks.
