RE: hat tip to .gov hostmasters
Correct, you need a validating, security-aware stub resolver, or the ISP needs to validate the records for you. That would defeat the entire purpose of using DNSSEC. In order for DNSSEC to actually provide any improvement in security whatsoever, the ROOT ZONE (.) needs to be signed, and every delegation up the chain needs to be signed. And EVERY resolver (whether recursive or local on host) needs to understand and enforce DNSSEC. If even one delegation is unsigned or even one resolver does not enforce DNSSEC, then, from an actual security perspective, you will be far worse off than you are now. Until such time as EVERY SINGLE DOMAIN including the root is signed and every single DNS Server and resolver (including the local host resolvers) understand and enforce DNSSEC you should realize that DNSSEC does nothing for you whatsoever except give the uneducated a false sense of security. It is likely that IPv48 will be deployed long before DNSSEC is implemented.
RE: hat tip to .gov hostmasters
DNSSEC is not a PKI. There are no CAs and no X.509 certificates. It's a chain of trust that can be validated using public/private key pairs. OK, that's oversimplification but you get the idea. While we wait for applications to become DNSSEC-aware, if your local DNS server can be trusted (a big if of course) then it can proxy the DNSSEC awareness for you. Since nearly everybody trusts a local DNS server to resolve queries, then making that server DNSSEC aware is an enormous step forward, even if the actual applications and operating systems on end-user computers are not fully DNSSEC-aware and won't be for many years to come.

Sure, they mention that vendors are rolling it out and that ISPs should be following suit, but no mention is made of the end-user's resolver at all... I dunno, a few very strategically placed validating resolvers could subject a huge amount of DNS traffic to a much higher bar were the senders so inclined to sign their zones.

RE: hat tip to .gov hostmasters
That would defeat the entire purpose of using DNSSEC. In order for DNSSEC to actually provide any improvement in security whatsoever, the ROOT ZONE (.) needs to be signed, and every delegation up the chain needs to be signed. And EVERY resolver (whether recursive or local on host) needs to understand and enforce DNSSEC. Either the resolver needs to enforce, or the host. It's not necessary to do both. It's also not strictly necessary that the root is signed, provided that there is some way to manage the trust anchors (either through software updates, like it is done for the browser CA list, or through regular DNS management at the ISP resolver). If even one delegation is unsigned or even one resolver does not enforce DNSSEC, then, from an actual security perspective, you will be far worse off than you are now. Why? If the local resolver does not perform DNSSEC validation, then I cannot validate that the response is correct. I certainly do not trust anyone else to verify that the information is correct and then, without any possible verification, simply believe that the third party did the validation. In fact, I have no way of knowing that the response even came from the ISP at all unless the client resolver supports DNSSEC. Just because YOU check the digital signature on an email and forward that email to me (either with or without the signature data), if I do not have the capability to verify the signature myself, I sure as hell am not going to trust your mere say-so that the signature is valid! If I cannot authenticate the data myself, then it is simply untrusted and untrustworthy -- exactly the same as it is now. The real problem is that the clueless (with a hidden self-aggrandizing and a primary motive of lining my pockets with other peoples money will convince the ignorant that it is more secure. Sort of like banning toothpaste from carry-on baggage impoves the security of air travel, when in fact it does nothing more than help the idiots in charge of promulgating such polies to rip off (rob) other people of their money by deliberate fraud and misrepresentation. Until such time as EVERY SINGLE DOMAIN including the root is signed and every single DNS Server and resolver (including the local host resolvers) understand and enforce DNSSEC you should realize that DNSSEC does nothing for you whatsoever except give the uneducated a false sense of security. DNSSEC is totally invisible to the end user. There won't be any browser icon that says it's okay to enter your PII here because the zone is DNSSEC-signed. It's purely an infrastructure measure, like physically securing your routers. The end-stage is secure only if at that stage you also set all DNS infrastructure to refuse to talk to any DNS client/server/resolver that DOES NOT validate and enforce DNSSEC. Up until that point in time, there is NO CHANGE in the security posture from what we have today with no DNSSEC whatsoever. To hold forth otherwise is to participate in deliberate fraud and misrepresentation of material facts.

You are confusing validating signature with validating the holder of the keying material and the authorization of the holder to deploy it to create a non-repudiable signature, which are two entirely different and completely unreleated things. (This is quite common by the way, so maybe you can be excused your confusion). If there is a piece of data X signed with a cryptographically generated signature, and *I* verify that indeed the signature is valid, then the signature is valid -- that is, I can say with 100% absolute certainty that specific bit of keying material was used to generate a signature on something and that I have another bit of keying material which validates that signature. I am assured with very high certainty that THE DATA WAS SIGNED BY THE POSSESSOR OF THE SECRET KEYING MATERIAL. Nothing more can be determined from the signature. You now want to confuse the issue by associating the keying material with a person or entity. That problem is entirely outside the purview of the exercize and completely irrelevant. (I certainly do not trust that any certificate issued by a so-called Certificate Authority (other than myself) was issued to the entity it is purported to be issued to, nor that the key is properly kept secret, nor anything else. The mathematical validity of the signature is beyond question. Associating that signature to anything other than a mere statement that this data was signed by the possessor of the secret key corresponding to the public key that I have is a personal judgement call.

Unlike things like the IPv6 requirement, there are no waivers available for this. '.gov' must be signed early next year and all zones delegated from the '.gov' GTLD must be signed in early 2010. I doubt that many will sign until '.gov' is signed, so you won't see much change for a few months.

Slight clarification: you need a validating, security-aware resolver, whether that resolver is local (e.g., running on the same machine issuing the DNS queries) or remote (e.g., your ISP's resolver).

Subject: RE: hat tip to .gov hostmasters Date: Mon, 22 Sep 2008 11:49:50 -0400 From: Keith Medcalf [EMAIL PROTECTED] If I cannot authenticate the data myself, then it is simply untrusted and u= ntrustworthy -- exactly the same as it is now. Speak for yourself, John applies. In the real world, there are cases where data that one is unable to authenticate by ones self *is* treated as fully trusted. Because someone with the authority to declare it to be that, by fiat, has done so. There may be a common chain of command, and someone higher in the chain has declared that various inferiors shall(i.e. 'must') trust the work of other inferiors within the organization, for example. Or, it may be a contractually-delegated trust. Or, any of a number of other possibilities. Admittedly, in any of those scenarios, the 'strength' of trust is somewhat weaker than if it was self-verified, but it _is_ far above your claim of 'untrusted and untrustworthy'. The end-stage is secure only if at that stage you also set all DNS infrastr= ucture to refuse to talk to any DNS client/server/resolver that DOES NOT va= lidate and enforce DNSSEC. Up until that point in time, there is NO CHANGE= in the security posture from what we have today with no DNSSEC whatsoever. FALSE TO FACT. One does not have a _guarantee_ of 'accurate' data without end-to-end enforcement, this is true. Even _with_ end-to-end DNSSEC enforcement, one does not have such a guarantee. All it accomplishes is to make the insertion of bogus data harder. Not 'impossible', just 'harder'. If a local non-DNSSEC resolver consults _only_ a DNSSEC-aware server on an immediately adjacent network, it takes only a moderate 'extension of trust' to (a) the local network operator, (b) the adjacent network operator, and (c) the DNSSEC-aware server operator, to have a reasonable degree of trust in the accuracy of the data the local reslover has. This 'trust' involves the physical integrity of the networks -- that a host on -those- networks will not be allowed to spoof a source address of the DNSSEC-aware server; and the use of ingress-filtering on _source_ addresses -- to prevent any 'external' network/machine from spoofing it either. Beyond that, it is just a matter of 'trusting' a proper implementation on the server itself. _IF_ the anti-spoofing provisions are in place, and 'downstream' (non-aware) DNS resolvers (which consult -only- the 'aware' server) are under the same administrative control as the DNSSEC-aware one, *THEN* there is zero effective difference in the trust level for an answer obtained from the 'non-aware' system as one obtained from the 'aware' one. To hold forth otherwise is to participate in deliberate fraud and misrepres= entation of material facts. This really sounds like someone who has a financial interest in promulgating FUD. grin
RE: hat tip to .gov hostmasters
To digress on IPv6 momentarily.
The airline magazine engineering memorandum* from OMB left two terms
undefined in the mandate; backbone network and IPv6 compatible. The
Intra-agency IPv6 Federal Working Group wisely defined backbone
network as (paraphrasing) the wire exiting the first publicly-reachable
network perimeter router and entering the router next in the line of
traffic and all devices attached to that wire between those two points
as follows:
{Internet}-|router|-connecting wire---IPV6-[firewall, IDS,
etc.]-IPV6--connecting wire-|next router in line|-NO IPV6-...
NIST is still working on compatible.
*Airline Magazine Engineering Memorandum: a mandate issued by an
executive who can. The memorandum has four characteristics; 1) It
mandates a technology not well understood by either the issuer or the
recipient of the memo, 2) it sets a date certain by which the technology
must be implemented, 3) it provides no funding, and 4, it contains one
or more undefined terms whose exact meanings are absolutely crucial to
actual implementation of the mandate. Source of the inspiration that
originally convinced the issuing executive that they actually understood
the scope and technology of the mandate is inherent in the title of this
paragraph.

nice to see a wholesale DNSSEC rollout underway (I must confess to
being a little surprised at the source, too!). Granted, it's a much
more manageable problem set than, say, .com - but if one
US-controlled TLD can do it, hope is buoyed for a .com rollout
sooner rather than later (although probably not much sooner :)).
It ain't done yet.
I don't speak for the hostmasters of .gov or any subdomain thereof.
But I'll believe it when I see it.
I am pretty sure that you will see it. Unlike things like the IPv6
requirement, there are no waivers available for this. '.gov' must be
signed early next year and all zones delegated from the '.gov' GTLD must
be signed in early 2010. I doubt that many will sign until '.gov' is
signed, so you won't see much change for a few months.
Now, if the DOC people responsible for root would just catch a clue, we
could get that signed and have DNSSEC actually usable (except for Mr.
Metcalf) in a significant part of the US network before I retire.
Remember, they've also mandated IPv6 support on all backbones.
Yes, and the goal, relatively insignificant that it was, was met. It was
not a requirement that anyone actually use IPv6, only that the agency
backbone networks be able to carry IPv6. In fact, the wording was such
that doing proper routing was not even really needed.
Our backbone has offered IPv6 as a production service since 2002, so it
was a non-effort for us. Most other agency backbones were pretty trivial
to make IPv6 capable.
The problem is that only the backbone currently needs IPv6. No facility
network or end host needs it, No network service needs it. No IPv6
packets, even routing updates, need to be delivered in any useful way.
It was a pretty trivial goal and was met with very little effort.

favourite XFP supplier?

RE: Atrivo/Intercage
Just to add my $0.02 to this discussion and a disclaimer - I've known Emil for years, I've seen his shop and even the controversy. 200 Paul is a small community, and most of the folks in there know eachother, I've been in there since 2001 or so. Intercage is not a big shop, there are very few people involved in running it and I have a very hard time believing the accusations made by some of the folks around. I also don't believe Intercage was complicit in any net-crime; Thats not to say it didn't exist, but more along the lines of they got lost in the noise of running a business. I'd guess that given the server volume they've got, abuse emails are less than one percent of all the email they get in a week. From what I've seen, the bulk of their customer base is webhosters, Unix Shell providers and some video/audio streamers. Were I to venture a guess on the number of folks reselling those webservers, its probably on the order of thousands... Any time I've had an issue with one of Atrivo's customers, it only took one email to get it dealt with, or I got Emil on IM or on the phone and it was taken care of. My experience with being on the other end of abuse@, I'd say a good 60-75% of the complaints I saw coming in were bogus. Either people complaining about their ZoneAlarm's going off, people complaining about bounced emails with spam and a bunch of automated stuff that was always wrong. The legit complaints were not always easy to deal with either since a good 20-30% of them were unclear on what was actually wrong until you spent some time digging. Basically is what it boils down to for me - its easy to blame an NSP/ISP/Hoster for what their clients do, it takes real dedication to find out whats *actually* going on. -- Tom Sparks (415) 367-7328x1001

If we had to deal with so many abuse complaints that things were getting lost in the noise, I'd have to seriously examine my AUP and associated enforcement policies, add staff to handle abuse issues, or both. Being small isn't an excuse. In fact, a small shop that runs a clean network should be far better at handling abuse issues than the larger players could ever hope to be.

Tom, Atrivo is not just a spammer, and Intercage has _not_ taken care of problems - unless you count moving IP addresses around as taking care of things. I'm sure the people downloading child pr0n or hosting virus / CC servers were very inconvenienced from having to change a hostname. Pardon me if I am incredulous. And not because we were not dedicated in trying to find out what was *actually* going on. Try reading up on your friend before accusing the community of not doing due diligence. And don't give me any BS about not reading his abuse@ mail. Eventually ignorance (willful ignorance?) in the service of evil becomes indistinguishable from malice.

Fluxlight (www.fluxlightinc.com) is good source for 10GBASE-SR and LR XFPs.

If you have a Dell Premier account, you might want to check there, as they usually have XFPs listed at steep discount...

The application just rejects the answer. Trys again a couple of times then reports failure. This is no different to the application talking to the validating resolver a couple of time and then reporting failure. The advantage of having the application do it is that you don't need to secure the connection between the validating resolver and the application. Mark

prefix hijack by ASN 8997
I am hoping to confirm a short-duration prefix hijack of 72.234.0.0/15 (and another of our prefixes) by ASN 8997 (OJSC North-West Telecom in Russia) in using ASN 3267 (Russian Federal University Network) to advertise our space to ASN 3277 (Regional University and Scientific Network (RUSNet) of North-Western and Saint-Petersburg Area of Russia).

If the above two are correct, would it be correct to say only the downstream customers of ASN 3267 were affected? scott

Re: prefix hijack by ASN 8997
At first glance this morning not seeing any data between the gain and lost alerts from phas and inability to find a route in any of the many collectors and route servers out there I had thought it was a possibly a fat finger mistake by 8997 or a false positive. After locating the data in bgplay/rviews, and noticing how many more people this occured to I'm leaning towards 2 possible scenarios: 1 - bgp misconfigurations leading to leaks (Depends on the overall scale of how many other prefixes were possibly announced) 2 - 8997 began announcing prefixes as an experiment to test the waters for potential real hijacks in future... 'geography' hints towards #2 Or both theories could be way off :) I'd be interested to know if Renesys collected any data that might give some better insight to this...

Bgplay on routeviews, not the ripe one :) Christian On 9/23/08, Hank Nussbacher [EMAIL PROTECTED] wrote: On Mon, 22 Sep 2008, Christian Koch wrote: Strange that RIPE RIS search doesn't show it: http://www.ris.ripe.net/perl-risapp/risearch.html but yet you say BGPlay does show it. -Hank I received a phas notification about this today as well...
