Is there a line of defense against Distributed Reflective attacks?
by Brad Laue 23 Jan '03

23 Jan '03

Having researched this in-depth after reading a rather cursory article on the topic (http://grc.com/dos/drdos.htm) only two main methods come to my mind to protect against it. By way of quick review, such an attack is carried out by forging the source address of the target host and sending large quantities of packets toward a high-bandwidth middleman or several such. To my knowledge the network encompassing the target host is largely unable to protect itself other than 'poisoning' the route to the host in question. This succeeds in minimizing the impact of such an attack on the network itself, but also acheives the end of removing the target host from the Internet entirely. Additionally, if the targetted host is a router, little if anything can be done to stop that network from going down. One method that comes to mind that can slow the incoming traffic in a more distributed way is ECN (explicit congestion notification), but it doesn't seem as though the implementation of ECN is a priority for many small or large networks (correct me if I'm wrong on this point). If ECN is a practical solution to an attack of this kind, what prevents its implementation? Lack of awareness, or other? Also, are there other methods of protecting a targetted network from losing functionality during such an attack? Insights welcome. Brad -- // -- http://www.BRAD-X.com/ -- //

aol and 69.0.0/8
by Scott Granados 23 Jan '03

Anyone hear of aol not allowing in 69.0.0.0/8 addresses. It was just claimed to me but I thought that seemed highly unlikely.

Something I'm surprised no one has commented on considering the direction of this thread has been should ISPs be responsible for customer actions if they are not allowed to refuse service to customers? I'm surprised this hasn't come up since the latter half of the question also represented a fairly "popular" thread earlier. I'm interested in people's opinions.

Security Flaw Exposes 35 Million AOL Accounts

Stones and glass houses. Not to throw stones, but to learn how to build better glass houses. California's SB 1386 doesn't become effective until July 1, 2003. http://www.betanews.com/article.php3?sid=1043252353 Security Flaw Exposes 35 Million AOL Accounts By Nate Mook and Craig Newell, BetaNews January 22nd, 2003, 11:19 AM The accounts of millions of AOL subscribers were jeopardized this week due to a serious flaw in the company's Web-based mail system, BetaNews has learned. The vulnerability stems from an error in one of AOL's international e-mail authentication systems, which granted users access without correctly verifying passwords. By simply entering an account name, an AOL user had the ability to read any other user's e-mail and all personal data contained therein.
