[SOLVED] Firewall Filtering

Firewall systems enable network security administrators to control the flow of data in and out of a network by enforcing rule sets that permit or deny traffic based on various criteria, including IP addresses, TCP and UDP port numbers, transport layer sequence numbers, and application header information. Pick one of the following filter criteria to discuss. Choose a criterion that has not yet been exhaustively covered in the existing posts. IP address. TCP and UDP port numbers. Transport layer sequence numbers. Application header information. Discuss how your chosen filter criterion works to permit or deny network traffic. Suggest a placement for the firewall enforcing the filtering rule within the context of an enterprise network.
