[ISSForum] TCP_Port_Scan

from [Soldatov, Sergey V.] Network Security [Permanent Link]
Subject: [ISSForum] TCP_Port_Scan
Date: Fri, 13 Jan 2006 15:29:12 +0300 
Hi list!
In my SP console I see a lot of TCP_Port_Scan events for Internet IPs to
my local IPs. I suppose that this are  false positives because of HTTP
replies from visited Web-sites, but unfortunately I can't figure out if
it's so, because SP (and it's strange) does not show attacker's source
port in event details... Does anybody can recommend something to help me
investigate these TCP_Port_Scan events.

May be someone have experience in tuning TCP_Port_Scan event?

Any feedback will be welcome.

Thanks!
