Why is BIG-IP ASM ideally suited to protect against layer 7 attacks, including HTTP and HTTPS/SSL traffic, when compared to an intrusion prevention system (IPS)?

Packet filtering describes traditional stateless firewalls, not IPS devices - IPS uses deep packet inspection and signature correlation, making this an inaccurate technical characterization.

Modern IPS appliances can perform SSL decryption to inspect HTTPS traffic, so lack of HTTPS visibility is not a reliable or universal differentiator between IPS and WAF capabilities.

IPS is not limited to operating system attacks - it detects a broad range of network, protocol, and some application threats, so characterizing it as OS-only is factually incorrect.

An IPS inspects traffic using signature and anomaly-based pattern matching at the network and transport layers, giving it visibility into overall traffic behavior but not into the specific application being served, its parameters, sessions, or expected workflows. BIG-IP ASM understands HTTP and HTTPS at the application level - including URL structures, parameters, cookies, and response content - allowing it to detect and block attacks that blend into legitimate application traffic, which a pattern-focused IPS would miss.
