Contents
Context Based Access Control (CBAC)
- filters TCP and UDP packets based on application-layer protocol session information.
- more flexible than access control lists, that checks packets at the network layer, or at most, the transport layer
- inspects packet sequence numbers in TCP connections
- detects unusually high rates of new connections and issue alert messages.
- creates temporary openings in the return acl to allow traffic back in.
Configuration
ip inspect name iosfw telnet ip inspect name iosfw
