Object
column SNMPv2-SMICounter64
A FIN scan sends TCP segments with the FIN flag set in an
attempt to provoke a response and thereby discover an active
host or an active port on a host. The use of TCP segments
with the FIN flag set might evade detection and thereby help
the attacker succeed in his or her reconnaissance efforts.
This attributes records the detection of the TCP fin set
without ack bit set packets.
