Not to take anything away from Steve Gibson nor his informative document, but read Microsofts response at: http://www.microsoft.com/technet/security/raw_sockets.asp Starrdust -----Original Message----- From: Irony [mailto:irony@trini.org] Sent: Wednesday, June 06, 2001 4:27 PM To: Firewalls@lists.gnac.net Subject: This is a must read document. It will freak you out - From time to time a "must read" document is published. Steve Gibson, author of ShieldsUp! and one of the gurus of Windows security lived through a major distributed denial of service attack and traced the attackers. He wrote an extremely readable tutorial on it. It's long, and worth every minute. Just one of his many interesting tidbits: Windows 2000 and XP, unlike their predecessors, have enormous capacity to generate malicious Internet traffic with spoofed IP addresses. http://grc.com/dos/grcdos.htm - [To unsubscribe, send mail to majordomo@lists.gnac.net with "unsubscribe firewalls" in the body of the message.] - [To unsubscribe, send mail to majordomo@lists.gnac.net with "unsubscribe firewalls" in the body of the message.]
