Subject: FW: Legal?  Road Runner proactive scanning.[Scanned]

You consider a port scan to be an attack?

Why is a port scan an attack?  Do other people on this list agree with this?

Perhaps I am naive,


Yes, I consider a port scan to be an attack.  It is a probe to inspect my 
system, quite often a precursor to an actual attack if performed 
successfully.

It is not unusual to look at a port scan in this fashion...

To be more explicit, sometimes a portscan can be an indicator of system 
problems elsewhere.  I once reported activity from one particular 
server...the owner replied that he wasn't running any sotware like that 
and after inspecting his box, found he had a rootkit installed.  The user 
of the rootkit was probing my system.

One offender found he had a virus-infected system out there...never had a 
problem after that.

I've correlated data between port-scans and failed attempts to exploit my 
ftp daemon.  Makes for some interesting stuff sometimes...

IMO, yes, a portscan is an attempted breach.
