|    Anti-DDOS alliance for webhosters idea.    |

      From: IntoTheFuture@hotmail.com              Hello,              (Anti-Distributed-Denial-of-Service-Attack-Alliance for Webhosters idea)              Webhosters could work together and couple their servers via special       software.              When a webhoster's servers come under attack from a DDOS it will ask for       help from other webhoster's servers. Perhaps just one at first to be able to       get a copy out.              The other webhoster servers will copy the files/websites which are under       attack from the victom webhoster. This other webhoster server will then add       itself to the DNS so that the DNS resolves to multiple ip addresses.              As the second web hoster comes under attack and is in danger of getting DDOS       it will ask again for help from another webhoster... perhaps the first one       as well... this procedure repeats until the DDOS is not effective anymore or       until all webhosters in the alliance have been consulted/requested for help.              When the attack is over the webhosters can slowly remove the copies at       random times in case another attack happens later on, in on on/off       fashion... when they remove the website they remove themselfes from the DNS       first as well.              Webhosters in the alliance could give other webhosters       pre-written-permission to add themselfes to DNS but only after a request has       been received, otherwise it's probably non of their bussiness.              If the attackers chose to attack many different websites then there is a       risk of copy explosions, so the websites which were under attack the longest       ago are removed first when the harddisks become full. So first in first out.       (This gives prevelance to the websites which are most recently under       attack.)              This alliance could ofcourse be abused by "cheap" webhosters which simply       have too little servers and too little bandwidth.              Thus webhosters in the alliance would need monitoring software and perhaps       alerts specially for this alliance feature/software.              Then they can monitor any abuse of the system. Perhaps ISP's could also be       included into the system to provide information about the system/webhoster       that is under attack to be able to verify if it's a true attack or just       being cheap.              Such monitoring requests would only be honered if the website under attack       gave permission to the ISP to monitor and send this information to others to       be able to prove that it's indeed under attack. If such approval was not       giving by the webhoster then it is assumed it's a fake and it's being cheap.       If the ISP does not want to work with the webhoster and does not want to       provide information then there is a problem, then it's up to the other       webhosters to make a guess if it's a genuine attack or being cheap.       Different solutions for this case are thinkable: defaults could be: 1. Copy       and disable manually later if doubts about genuine attack. 2. send alert and       ask for manual permission to copy 3. Deny a copy.              Once the attack is over this sharing-of-monitoring-information approval is       revoked.              And all can return back to normal.              Bye,        Skybuck.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
