system is a protection mechanism based on adaptive Security Algorithm (ASA), which can provide a stateful firewall with connection-oriented capabilities. Using ASA,FWSM, you can create a connection table entry for a session stream based on the source and destination addresses, random TCP serial numbers, port numbers, and other TCP flags. FWSM can control the flow of all inputs and outputs by enforcing security policies on these join table entries.
