Going forward we require new vendors to be able to: 1. trace spoof address based attacks in a reasonable time 2. block spoofed attacks from coming from their customers 3. have a mechanism to repair or block amplifying addresses owned by their customers If the vendor won't commit to doing these things, we will not buy service from them. Ask my UUNet rep, she'll testify to this. UUNet is losing a potential $200,000 a month because they are not capable of tracing spoofed attacks. Instead I give my business to GTEI and Digex because both companies have been very cooperative when asked to do these traces. Anyway the point is that when money is involved, leverage is available. These things can be fixed, it's just a matter of applying the right pressure. Brandon Ross Network Engineering 404-815-0770 800-719-4664 Director, Network Engineering, MindSpring Ent., Inc.
