A packet filter is a mechanism used to provide a level of digital security by controlling the flow of information (data packets) via the examination of key information in packet headers. A packet filter determines if these packets are allowed to go through a given point based on certain access control policies. A dynamic packet filter (DPF) builds on the concepts of a normal packet filter but with increased intelligence. Traditional packet filters are often slower and more difficult to manage in larger networks with complex security policies A stateful packet filter (SPF), quite simply, manages and maintains the connection state of a session through the filter to ensure that only authorized packets of a policy are permitted in sequence.
