[gnso-rds-pdp-wg] Principle on Proportionality for "Thin Data"access

Tue May 30 22:19:14 UTC 2017

Rob, 

As I said, it was a way of abuse. Not all DNS providers (or registrars for that matter) point out that the persons email address could be placed into the DNS zone file. Nor mentioning that it could be changed for that matter. 

Kind regards, 

Chris

Sorry, that’s not likely a valid example. That information is made public by publishing it in the DNS in the first place, by the direct decision of the publisher (DNS operator). If the nameserver records aren’t in the DNS, the domain doesn’t work and if the nameserver records aren’t in the DNS, you can’t get the SOA record. All I need is the domain name to start with, dig the nameservers for the domain, and then dig the SOA. Importantly, I DO NOT NEED “whois” or anything else similar to get to these data records, so these are all public data points that anyone can anonymously access at any scale for all operational domains on the Internet. Publishing the same data (nameserver related to domain) in a different database (whois, RDS, whatever) doesn’t make it more public - it’s been put out there already. 

For those of you not familiar with the intricacies of how DNS SOA (Start of Authority) records work, the third entry on each line in the examples below is actually an e-mail address, where the first dot should be replaced by an “@“ symbol. So for the first one, the e-mail address for the entity claiming authority over the gmail.com zone is dns-admin at google.com . As Chris mentioned, these are going to largely be technical contacts, but not always. However, that’s the purpose for the field - technical authority over the zone, so putting your “personal” information into that field would mean you want to publicly publish your e-mail address in the DNS so anyone can reach it. I don’t think we’re trying to tell people to *not* do things like that in this WP. Regardless, you have to supply a validly formatted SOA record for DNS to work, including an entry that is plausible as an e-mail address for that field. That doesn’t require the e-mail address to be answered, monitored, or even deliverable, so you could put test.test.com ( test at test.com ) in there if you don’t want things to be sent to you. If I remember right, some ccTLD’s would require that you actually answer a query to the SOA e-mail “back in the day” to delegate your domain - not sure if any do anymore. For far more arcane trivia around SOA records etc. see the wikipedia entry ( https://en.wikipedia.org/wiki/SOA_Resource_Record ) or this handy tutorial ( https://bobcares.com/blog/understanding-soa-records/ ). It goes all the way back to the original DNS spec in RFC 1035. 

Cheers, 

Rod

ok - a thought : 

Thin data includes nameservers, being able to mass collect thin data gaining NS information then allows you to do a DIG of a SOA record on the DNS service to gain the email address of the hostmaster : 

Some examples (radomly picked from the list) : 
gmail.com : 
SOA ns1.google.com . dns-admin.google.com . 157458041 900 900 1800 60 
netearthone.com 
SOA ns1.netearth.net . root.netearthone.com . 2016090201 14400 3600 1209600 86400 
law.es 
SOA ns1.eurodns.com . hostmaster.eurodns.com . 2016061402 43200 7200 1209600 86400 
riskiq.net 
SOA ns-1754.awsdns-27.co.uk . awsdns-hostmaster.amazon.com . 1 7200 900 1209600 86400 

Now as you can see - those above examples allow you to get (or build) an email list. Most will normally point to the providers service, but, some that are DIY'ing their hosting, it might not be. 

Kind regards,

so can you name one specific example of how someone could abuse thin data?

Abuse is the improper usage or treatment of an entity , often to unfairly or improperly gain benefit. In our context, abuse is the improper usage of WHOIS/RDS to unfairly or improperly gain access to information or to game the system. 

Here are some of the overarching principles which should guide us when building RDS: 

DATA LIFECYCLE PRIVACY PRINCIPLE PROTECTION MEASURE 
Collection Proportionality and purpose specification Data minimisation, Data quality 
Storage Accountability, Security measures, Sensitive data Confidentiality, Encryption, Pseudonomisation 
Sharing and processing Lawfulness and fairness, Consent, Right of access Data access control, Data leakage prevention 
Deletion Openness, Right to erasure Retention, Archival, Erasure 

If such principles are not respected, ICANN will be liable. Consumers don't need to have all the thin data when making a query. This could protect them and enable them to have access to the RDS without raising much opposition. 

Now, we could discuss the possibility for broader query types. These principles would still apply, but would be contextualized in order to take into account new sets of parameters for each broader query. By increasing granularity as much as possible, while applying these aformentioned principles, we just might find a way to accomodate everyone.

Natalie, 

Thank you for the email. Im copying the list because i see others have replied to your comment. 

I strenuously object to the concept. We are discussing THIN DATA ONLY HERE. Unless someone can explain to me why any of this data set has privacy concerns this is a non-issue. I would certainly appreciate someone explaining what, if any, privacy issues are perceived to be at issue here. 

Moreover, while you suggest that the idea escapes the need to declare a purpose, it does nothing but reinforce a subjective criteria based system in which the declared purpose is used to somehow limit the data being retrieved. 

If i am missing something please let me know.

Hi Paul, 

In the context of thin data, in view of the opposition of some to allow unauthenticated access to all the thin data, the principle of proportionality serves as an over-arching principle at this particular phase in our work in order to protect data from abuse while not restricting access. 
Thin data must be proportionate to the query, be useful for that particular query. All and any other thin data foreign to this query should not be shared. This principle potentially avoids having to resort to 'legitimate purposes' which cannot be verified for unauthenticated access.

All, per today's call action item: 

Action Item: Nathalie Coupet and any other WG members who wish to do so to propose to the WG list a new principle on proportionality for "thin data." All WG members to comment on that proposed principle in advance of next call. 

we are starting a new thread here which anyone may reply to if they wish to propose (or respond to) a new principle on proportionality for "thin data" access. 

Best, Lisa
