Analysis of Packet Filtering Technology in Computer Network Security?

? in today’s networks are becoming more complex, and the demands on bandwidth are through the roof. In achieving visibility for the best network performance, monitoring the right data is critical. Explore a network monitoring switch tool that provides advanced filtering options that are able to quickly resolve network problems and add on new capabilities as future requirements come along, without much manual effort to maintain an updated set of filtering rules. Packet filtering has proved to be a handy tool to put access controls to IP traffic. Packet filters can be used to block IP packets based on certain criteria such as the protocol used and various protocol characteristics. On the Internet, packet filtering is the process of passing or blocking packets at a network interface based on source and destination addresses, ports, or protocols.
