Would this also be an indication of a compromised machine on the local network? I'm guessing that it depends on what interface it was detected on. ________________________________ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Harrison Sent: Thursday, March 01, 2007 9:14 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Re: ISA Server dected a land attack - urgent Don't worry, be happy. The Internet is a wild & crazy place, with oodles and gobs of jerks, jackasses, 1d10t5 and full-blown @55h0135 who would like nothing better than to make your life harder if for no other reason than to say they did it. The fact that ISA can not only detect and block this sort of attack is a good deal. What's even better is that ISA (unlike so many LinkChekPix devices) can also communicate this to you so that you can revel in your safety. http://www.microsoft.com/technet/isa/2000/proddocs/isadocs/isa_15103.msp x?mfr=true Yes, I know that's an ISA 2000 link, but ISA versions don't change "land attacks".
