Integrating IPS Modules with Cisco IOS
Security Technologies
ƒ Cisco IOS Firewall and IPS Modules are
complementary technologies
Cisco IOS Firewall blocks unwanted traffic from entry into the
network, ensures that applications traffic is legitimate
IPS Modules inspect traffic the FW has allowed, as well as
traffic from the trusted network, to prevent attacks
ƒ Cisco IOS Firewall provides SYN Flood attack defense
ƒ Cisco IOS Firewall and IPS Modules maintain separate
state tables for TCP traffic
Resets from one state table force session timeouts in the other
