This message has two purposes. It is addressed to the ENUM WG with the purpose of determining consensus in this WG on the proposal from Antoin Verschuren. It is addressed to the DB and NCC-Services WGs as an inter-WG communication to alert these WG's to expect a consensus in the ENUM WG and a request from ENUM WG for related changes to the RIPE database.

org: question
by Max Tulyev 18 Oct '06

18 Oct '06

Hi! As a LIR, I have org: object (with org-type: LIR). But I can't use it in my objects, because of there is mnt-ref: RIPE-NCC-HM-MNT. The question is why? -- WBR, Max Tulyev (MT6561-RIPE, 2:463/253@FIDO)

Deprecation of CRYPT-PW authorisation from the RIPE Database
by Agoston Horvath 16 Oct '06

16 Oct '06

Dear colleagues, I would like to inform you that the project to deprecate CRYPT-PW authorisation in mntner objects in the RIPE Database is scheduled to start this week. Regards, Agoston Horvath Software Engineering Department RIPE NCC -------- Original Message -------- Subject: [db-wg] Proposal to deprecate CRYPT-PW authorisation in the RIPE Database Date: Wed, 4 Oct 2006 15:48:12 +0200 From: Katie Petrusha <katie(a)ripe.net> To: db-wg(a)ripe.net Dear colleagues, Here follows the proposal to deprecate CRYPT-PW authorisation in mntner objects in the RIPE Database. Comments would be appreciated. Background and motivation ------------------------- In the RIPE Database there are several authorisation types currently supported: CRYPT-PW, MD5-PW, PGPKEY and X509. These authorisation types define what kind of authorisation tokens can be used in "mntner" objects. CRYPT-PW authorisation type is based on UNIX crypt() functionality and is vulnerable to both dictionary and brute force attacks given the fixed password length and lack of cryptographic strength given today's computing power. While maintaining and protecting objects in the RIPE Database is the responsibility of the respective maintainer, the RIPE DB WG agreed that it's the responsibility of the community to ensure that only appropriate tools and algortihms are used and maintained. Since CRYPT-PW does no longer fulfill this requirements with the reasons given above, the WG also agreed to phase out CRYPT-PW. PGPKEY and X.509 have been the recommended authentication schemes for some time (http://www.ripe.net/db/support/security/security.html) MD5-PW shares two weaknesses with CRYPT-PW: passwords are sent in clear together with update requests and MD5 is vulnerable to dictionary attacks,as well. Still, MD5-PW will not be phased out together with CRYPT-PW, since at least the dictionary attack can be prevented by chosing passwords or pass phrases of appropriate length and entropy. MD5 offers a short path of migration away from CRYPT-PW without major change in processes. LIRs should, however, seriously consider a migration towards a public key based authentication scheme (PGPKEY or X.509). The MD5-PW method will be addressed separately. We propose to deprecate the CRYPT-PW authorisation step-by-step. Affected objects ---------------- There are currently ~3500 mntner objects in the RIPE Database that have only CRYPT-PW authorisation. There are about 300 mntner objects that have mixed authorisation of CRYPT-PW and some other authorisation types. Plan ---- 1. Gather mntner objects: group A: only CRYPT-PW authorisation group B: CRYPT-PW and (PGP or X509 or MD5) authorisation 1a. E-mail the contacts of those mntner objects (notify, admin-c, tech-c, mnt-nfy) to notify them about the coming change. 1b. notify the DB-WG mailing list 1 month later: 2. Modify the RIPE Database software: 1) reject any change to mntner object that adds new CRYPT-PW. 2) show a warning if CRYPT-PW was used during authorisation. 3) show a warning if object being updated still contains (existing) CRYPT-PW. 2a. E-mail the contacts of the mntner objects (notify, admin-c, tech-c, mnt-nfy) notifying them about the change and the next steps. 2b. notify the DB-WG mailing list 1 month later: 3. Modify the RIPE Database software: 1) disable CRYPT-PW in the syntax 2) disable CRYPT-PW in authorisation 3a. Modify mntner objects. group A: auth: is changed to MD5-PW, new password generated. group B: auth: CRYPT-PW is changed into "remarks" line "remarks: "your object was modified due to CRYPT-PW deprecation" is added 3b. Notify the contacts of the mntner objects: group A: explanation about the changes done, and URL with details on how to 'recover' the locked mntner object (similar to NONE deprecation process) group B: explanation about the changes done 3c. notify the DB-WG mailing list 4. Finished.

FW: FW: FW: FW: FW: [db-wg] Proposal to deprecate CRYPT-PW authorisation in the RIPE Database
by Potapov Vladislav 06 Oct '06

Hi, ---Gert Doering--- The information in the RIPE DB, especially the route: and aut-num: objects, are very closely tied to operational issues. A number of large networks (specific example: Cable & Wireless, AS1273, our upstream provider) are using this data to build their BGP filters. This is very much "hard tied to operational issues". ------------------ Gert, you know very well that the RIPE DB is not the only DB in the world. It is inaccurate at the moment in many cases. There are several networks which are not in any DB. "The large networks" may use SOME DB records, yes, but they use other ways to build their configuration too. They HAVE TO live in the real world. It's their "operational issues". Then they can live with it further. I think that sort of global changes for so many users of the DB (not "lookers" but a sort of "data administrators") should be done with their opinions and their "operational issues" taking into account but not the only "big fish players. Vladislav Potapov Ru.iiat P.S. To Max Tulyev:"I will be so thankful if you will point me to the law ;)" I won't do that for many reasons. In the Internet there are many answers to your questions.

Hi! ---Max Tulyev--- In Russia ALL uncertified by goverment cryptographic system is illegal. So SSL (lirportal) is illegal. But PGP/MD5/CRYPT is NOT illegal, because it don't do encryption and not interfere with SORM (SORM - a mandatory part of any ISP in Russia, that do hidden analysis and mirroring some of traffic to FSB), but only do signatures. ---- I can say that you are wrong. There are many proves of that. ---Max Tulyev--- Also, unlike PGP, lirportal can't do safr multiply persons authorization (i.e. owner of PI space creates route object with his upstream's AS, signs it, sent to upstream, upstream signs it too and send to RIPE). ---- Are we going to discuss a new proposal already instead of existing? :) The way you have mentioned works just so ONLY because the method (e-mail) used for the problem resolution. You himself (I don't even mean the community) can suggest much more easy and preferrable method of multiply person authorisation by a web-site (lirportal). Vladislav Potapov Ru.iiat

Hi! > Vladislav! If you wish to be really constructive - do policy > proposal for shutting down MD5-PW - personally I will vote > for that too. Max, I'm not a reactionary as you may think. I'm not against changes to the better. But it should be adequate, effective and universal for the region it serves. I don't know why you start to think on behalf (and propose against) of the 3500 other members using the scheme. If we got to the stage of a new proposal then maybe we should drop e-mail as a way to change the objects in the DB? It will be more constructive than shutting down both "password" ways. At least this way solves the "crypting mail prohibited" problem together with crypting ALL conversation (not only password part) and many more (and much more productive that the halved currently proposed "step"). The mechanism for that is already here - lirportal.

Hi, ---- From: db-wg-admin(a)ripe.net [mailto:db-wg-admin@ripe.net] On Behalf Of Max Tulyev If to be seriously, I'm showing until weak schemes will be exist, people (even so serious) *WILL* use it. Education will *NOT* helps to solve the problem (so, try ;) ). ---- Then it's better to start banning people who do not agree with you? It's much more simplier than discuss, educate... ---- From: db-wg-admin(a)ripe.net [mailto:db-wg-admin@ripe.net] On Behalf Of Max Tulyev I agree better is set off ANY password authorization. We can do it at least step-by-step, but leave it alone is the worst thing we can do. ---- I don't think that the matter even worst speaking about, because still nobody has answered that there has been any problem with existing schemes even for no-maintainer objects (it's one more way to ignore your attempts to strengten maintainer object). So "the worst thing we can do" is only words. The information in the DB is not accurate, representative or hard tied to operational issues, so the world will be there if it disappears completely (maybe slightly annoying for some players, not more).

Hi, -Hank >I think a number of people have pointed out why they wish to deprecate crypt-pw. No, I'm not convinced. And a number of people - only Gert Doering? The point of view they propagate - it should increase security (in reality - not). But, we all know: false sense of security is worse than knowledge of a problem. -Hank >To answer your latest points - data in the DB should be accurate and it does show who is allowed or not allowed to use a range of IPs, and if the data does 'disappear' as you say, it will have operational impact on a number of ISPs that build their access lists from the data in the RIPE-DB. "Should be" != "is" And to now this inaccuracy has NO operational impact on nobody. -Hank >It would appear that you might be enjoying the ability to abuse certain RIPE objects with weak security and by deprecating crypt-pw we will be impacting your playground. Hank, I think it is very cheap accusation at first hand; you are not eligible to accuse me of something - the second; it (abusing) hasn't happened before to speak about it - the third. Speaking your way I can think that RIPE doesn't know where to put money and want us to allow spend them on the projects not well-thinked and useles. Please be more constructive! Let's not allow to go to personal accusation. Vladislav Potapov Ru.iiat
