-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We ran into similar attacks (couple days back) coming from non-spoofed address range (being initiated from valid prefixes). In working (w/ a co-worker of mine) on a network attack situation (trace process) for a 30,000 user location (serving 60 other school districts) running BCP38 & rate-limit which got ddos'd w/ about 8mpps. It appears that these attacks were coming from the inside which not only saturated devices along its way but also got amplified into several other networks also causing significant flaps to its peered connection (OC-xx). Besides being distracted with this incredible among of traffic flow our goal number one goal was to prevent this bleeding, thanks to the distributed monitoring sensors (maybe we got lucky) we were able to identify and sink-hole (null route) certain blocks (vlans) while we worked with the network/desktop team to isolate the infected machines. This was certainly a hair-pulling experience. The point that I'm trying to make here is, you can have data coming from a herd of comprised hosts (bots, self-propagating worms, spam-relays,fake http get request, backdoors, etc) that can attack against a well-protected system(s) so any kind of defense mechanism can/will get defeated. Then again, it doesn't mean one wouldn't want to follow well practiced prevention methods.

I don't want to detract from the heat of this discussion, as important as it is, but it (the discussion) illustrates a point that RIPE has recognized -- and is actively perusing -- yet, ISPs on this continent seem consistently to ignore: The consistent implementation of BCP 38. It is nothing less than irresponsible, IMO... Why _is_ that? - ferg -- "Patrick W. Gilmore" <patrick(a)ianai.net> wrote: [snip] There is no single "appropriately[sic] place" which can absorb 50Mpps. If you meant "appropriately placed" (as in topologically dispersed locations), a well crafted attack could still guarantee _at least_ a partial DoS from an end user PoV. It is essentially impossible to distinguish end-user requests from (im)properly created DoS packets (especially until BCP38 is widely adopted - i.e. probably never). Since there is no single place - no 13 places - which can withstand a well crafted DoS, you are guaranteed that some users will not be able to reach any of your listed authorities. This is not speculation, this is fact. All a good provider can do, even with 1000s of server, is minimize the impact of any DoS. [snip] -- "Fergie", a.k.a.

Jose's numbers are conservative. Given some mathematical acrobatics, I'd suggest examining some of the (shocking) number sin Microsoft's Security Intelligence Report (Google it) -- these are reflective: "Of the 4 million computers cleaned by the company's MSRT (malicious software removal tool), about 50 percent (2 million) contained at least one backdoor Trojan. While this is a high percentage, Microsoft notes that this is a decrease from the second half of 2005. During that period, the MSRT data showed that 68 percent of machines cleaned by the tool contained a backdoor Trojan."

This would appear, on its face, to be an easy exercise in educating the IPSs in the foodchain. Is there reasonable enough interest with NANOG to do that? If so, I volunteer to workshop at the next NANOG. But only if there is reasonable consensus to that effect. Or someone else could do it, too. :-) The point I'm trying to make is that if the community thinks it is valuable, then the path is clear.

passports for NANOG-39, Toronto
by Robert E. Seastrom 26 Oct '06

26 Oct '06

You may have heard that the US and Canada are going to start requiring passports for air travel between them beginning "soon". That date is currently set as 8 Jan 2007, which is before February NANOG. MERIT has noted this on the web site, but a cursory check of my list archives didn't turn up mention of it (sorry if I overlooked it; the last couple of weeks have been hectic), so I figured I'd include the pointer: http://www.nanog.org/mtg-0702/passport.html as well as a link to the State Department: http://travel.state.gov/passport/passport_1738.html Normal passport processing is "within six weeks", but that probably doesn't take the holiday season into account. If you don't have a passport already and plan to travel from the US to NANOG 39 in Toronto, getting on that project sometime in the next month or so would allow plenty of spare time. No reason to pay expedite fees if you don't have to. ---Rob
