How can a stateful packet filter determine whether a session is beginning or ending?
What will be an ideal response?
Two of the flags that are part of a packet's TCP header information, and that indicate whether a session is beginning or ending, are RST (Reset), which tells a host to immediately terminate a connection, and FIN (Finished), which tells a host to gracefully end a connection. If a session ends abnormally (if one system goes offline or a computer crashes) and neither RST nor FIN flag is received, the filter uses a timer to determine when to remove state table entries. The timer can be set to remove entries as soon as 60 seconds or as late as several days after a session ends.
