This document discusses the importance of application protection and the differences between traditional firewalls and application firewalls. It outlines some common attacks targeting applications like SQL injection, cross-site scripting, and parameter tampering. The F5 Networks application firewall protects applications from these threats using features like signatures for attacks and vulnerabilities, URL/parameter/cookie protection, and bot detection. It can be deployed in data centers, clouds, and as a managed service to secure all applications.
