Re: [FW1] what is port scan ? our IT auditor found hole!!
Hi,
I recommend you to revise your rulebase searching for all ports you
have permited to access through the firewall, specially that services
on ports 264, 265 (bgmp).
Port scan is a sequential method to detect opened ports based on
trying to open connections to a destination address of a range of
specificated ports. There are a lot of tools that implement that
idea. See http://www.nmap.org

Josué.
