Subject: Re: "portscans" (was Re: Arbor Networks DoS defense product) And why, pray tell, would some unknown and unaffiliated person be scanning my network to gather information or run recon if they were not planning on attacking? I'm not saying that you're not right, I'm just saying that so far I have heard no valid non-attack reasons for portscans (other than those run by network admins against their own networks).
I scan networks and hosts very regularly for legitimate diagnostic purposes as well as occasionally for curiosity's sake. I've never attacked any host or network that I was not directly responsible for. If you don't want the public portions of your network mapped then you should withdraw them from public view. BTW, please be one heck of a lot more careful with your replies. My original reply to you was not copied to the list and I did not give you permission to post a response quoting my words back to the list. -- Greg A.
