The Distributed DoS Attack

• Attack may not be noticed on "daemon" networks
• Attack may overwhelm victim site, making identification of all "daemon" systems difficult
• Only takes several hundred systems (especially if Internet 2 sites) to knock a large network off the Internet
• Multiple attacking systems at multiple sites means a long time to neutralize network and fully stop attack (especially on weekends)
• Interesting note: UW/Stanford testing HDTV over Internet2 was doing 40-400MBps at the time of UMN attack (August 19). Didn't do fist "live demo" at 500-600Mbps until September 9. (First major use of Internet2 was to DoS?).
