You have to understand Amy, these guys are a bunch of geeks. They don't understand what's important to a woman, or even how to treat a woman like a lady. This is what happens when they spend too much time with "email," and not enough time with "female." ;) That's also why they are married, and I am single. :-p
If it makes you feel good, then go for it.

It may be a waste but you forgot that I feel better now. That's something. Maybe it's a girl thing.
I also have a habit of creating protocols for stuff that shows up as unidentified traffic. I suppose that's a waste too because ISA handles
it whether it has a name or not. But it makes it easier on me.
Now I can look at the logs and when I see Denied and the rule is Drop This Connection, then I know what it is. Just like when I see HP Printer Broadcast protocol in the logs, I know what that is. (and how to stop
it)

Yep--- was there any "intelligence" in the blocking rule, or could someone do a simple port scan of the external interface from the NAT'd
internal LAN to automatically block all internal traffic? ;)

.02:
It seems like a total waste of time to respond to "scanscript, as everything is being blocked anyway- just notwith an explicit"block" rule. The presence of the "scan" alert tells youthat ISA is doingits job - AFAIAC, no other action is even necessary. Ifthere is someincessant attack from a persistent IP hammering away atpublished services andyou just don't want to see it, then put in a deny rule. Ifit is a bandwidthissue (like when I was getting Code Red attacks all day,every day) then blockit on the ISP side. But that costs money for that service,typically."strikeback" model, thenHowever, it does work.
If it is in the realm of "identified" attacks ala mythat is a different thing- and something that is deployedin a completelydifferent way to solve a different problem (lest someonetried to use thatspoketh to all:against me ;). Port scans and "noise" traffic an safely be ignored.

Think way back to your involvement with SBS in the Yahoo list. It was how I got invited to join that list; theexpansion ofwas being touted as the be-all, end-all to ISA port scan response.
I had to get really nasty (even for me) with the proponent of this technique before he finally backed down.
He still regurgitates this nonsense (among other senseless
meanderings) from time to time, but it's an easy head-slap.
For those not familiar, the BlockAttacker script was anto create athe ISA 2000 alert action example that used the client IPvariables, it turnedpacket filter blocking the "offending host". While it provided an excellent example of using ISA alert environmentisatools.org.out to be a great DoS tool as well and we pulled it fromremain nameless
Unfortunately, there is one (TSu) individual who shalltechnique to(Tony Su) who insists on singing the praises of this responseto sort outunsuspecting ISA admins. Luckily, he's not skilled enoughcalls than we dohow to port the script to ISA 2004 or we'd have more PSSdamn few ISPsnow.

I don't know that joke. I think it was before my time on the list. What's the block attacker script? Never heard of it.

Ask Tony for the BlockAttacker script. I'm sure he's still trying to support it. :-p
Tom has it right; you can generally ignore them, sinceaway? I've goteven care.

What should I do about a port scan that just won't goAn email totwo IP addresses port scanning my server around the clock.the owner bounced back, unknown email address.
Is there anything to be done?
