Summary of Proposal:

The current policy, “Abuse Contact Management in the RIPE Database” does not provide sufficient validation of sufficiently validate the actual availability of the abuse-mailbox. It provides a technical validation that the mailbox/server exists – but not whether it will accept new messages, whether it belongs to the right person/team to follow up the abuse case, or even if it is monitored.

As a result, some resource-holders resource holders (LIRs and end-users) End Users) might not keep this contact information up to date, or might use a non-responsive mailbox (which could be full or not actively monitored), or might even use a or fake mailbox. delete: </p> delete: <p> In practice, this contact becomes ineffective to report abuse and generally gives rise to security issues and costs for the victims.

This proposal aims to solve this problem and ensure by ensuring the existence of a proper abuse-c contact and the establishing a process for its utilisation.  utilisation.

2.0 About the "abuse-mailbox"

Emails sent to "abuse-mailbox" require manual "abuse-mailbox": insert: </p>

insert: <ul>
    insert: <li>
  • Require intervention by the recipient at some point, and may not be filtered, because in certain cases this might prevent receiving abuse reports, for example in a spam case where the abuse report could include the spam message itself or URLs or content usually classified as spam. delete: </p> delete: <p> The "abuse-mailbox" may initially send an automatic reply, for example assigning a ticket number, applying classification procedures, requesting further information, etc. However, it should insert: </li>
  • insert: <li>
  • Must not require the reporter to complete a form insert: </li>
  • insert: <li>
  • Must guarantee that the abuse reporter fills a form, as this would imply that each entity that needs to report an abuse case (a task that is typically automated) would be forced to develop a specific interface for each resource holder in the world that mandates filling forms. That scenario would be neither feasible nor logical, as it would place the cost of processing the abuse on those who submit the claim and reports and related logs, examples, or email headers are therefore victims of the abuse, instead of being paid for by those whose clients cause the abuse (and from whom they obtain income). delete: </p> delete: <p> By way of information, it is worth noting that it is reasonable to expect that the abuse reporting procedure sends, with the initial abuse report, the logs, a copy of the spam message (attaching an example of the spam email or its full headers), or equivalent evidence (depending on the abuse type). Likewise, it is reasonable to expect that the initial auto-reply email could specify that the claim will not be processed unless such evidence has been submitted, thus allowing the sender an opportunity to repeat the submission and include relevant evidence. This allows automatic reporting, for example, via fail2ban, SpamCop or others, keeping costs at a minimum for both parties involved. Commonly, if a ticket number has been generated, it should be kept (typically as part of the subject) through successive communications. delete: </p> received insert: </li>
  • insert: </ul>

3.0 Objectives of "abuse-mailbox" validation

The procedure, which will be developed by the RIPE NCC, must meet the following objectives:

  1. A simple process that guarantees the abuse contact is able to fulfil its functionality and allows the helpdesks that deal with abuse reports to verify that validation requests actually come from the RIPE NCC and not from third parties (which might involve security risks), avoiding, for example, a single "direct" URL for validation. delete: <br /> delete: <br /> delete: </li> delete: <li> Avoid exclusively automated processing. intended purpose.

  2. Confirm that the person performing the validation resource holder understands the procedure and the policy, that they regularly monitor the "abuse-mailbox", abuse-mailbox, that measures are taken, and that the abuse report receives reports receive a response.

  3. Validation Initial validation period of no longer than 15 days.

  4. If validation fails, escalate to the other LIR contacts and set a new validation period not to exceed 15 days.
delete: <p> The “initial” and “escalation” validation periods may be modified by the RIPE NCC, if deemed appropriate, informing the community about the motivation. For example, it could be longer for the first validation, once this policy is implemented, and shortened afterwards once the percentage of failures decreases, so the quality of the contacts increases and consequently a decrease in the average abuse response times could be expected. delete: </p>

4.0 Validation of “abuse-mailbox"

The RIPE NCC will validate compliance with the items above, both when the "abuse-c:" and/or "abuse-mailbox:" attributes are created or updated, as well as periodically, not less than once every six months, and additionally whenever RIPE NCC sees fit.

Lack of compliance will lead to a more exhaustive follow-up, in accordance with the relevant RIPE NCC policies, procedures or contractual requirements. delete: </p> delete: <p> The frequency of the periodic validation could be modified if the RIPE NCC deems this appropriate and informs the community of its reasons. For example, a single validation could be done in the first year, to facilitate adherence to the policy, and then the number of annual validations could progressively increase, reaching even quarterly ones, with the aim of improving the quality of the contacts.

5.0 Escalation to the RIPE NCC

Fraudulent behaviour (for example, an "abuse-mailbox" that only replies to the RIPE NCC's emails or to messages with a specific subject or content), or failure to comply with the remaining aspects of this policy (incorrect or lack of response to cases of abuse) responses to abuse cases) can be reported to the RIPE NCC for a re-validation as per section 4.0.

 

insert: <h3>

Additional information: insert: </h3>

insert: <p>

As a matter of clarification, the “initial” and “escalation” validation periods may be modified by the RIPE NCC, if deemed appropriate, provided it informs the community of its motivation for doing so. For example, in the implementation phase, the periods could be extended, and adjusted as a higher percentage of contacts become accurate. insert: </p>

insert: <p>

Similarly, the frequency of the periodic validation can be modified if the RIPE NCC deems this appropriate and informs the community of its reasons for doing so. insert: </p>

insert: <p>

For example, a single validation might be done in the first year to facilitate adherence to the policy. The number of annual validations could increase over time, perhaps becoming quarterly, with the aim of improving the quality of the contacts. insert: </p>

Rationale:  Rationale:

a. Arguments Supporting the Proposal

The Internet community is based on collaboration. However, in many cases this is not enough and we need to be able to contact those resource-holders (LIRs or end-users) End Users) who may be experiencing a problem in their networks and who are unaware of the situation.

This proposal solves this problem by means of a simple, periodic verification, and establishes the basic rules for performing such verification. It thus avoids unnecessary costs to third parties that who need to contact the persons responsible for solving the abuses of abuse from a specific network.

The proposal guarantees that the cost of processing the abuse report falls on the resource-holder causing the abuse resource holder responsible (or its customers, from whom they receive financial compensation for the service), instead of falling on the victim, as would be the case if they had to resort to a legal claim in an extreme case, thus avoiding claim. This avoids costs (investigation and in the worst-case in terms of investigations (and lawyers, solicitors, etc.) and saving etc. in the worst-case) and saves time for both parties.

Having an equivalent policy in different regions, regions has the advantage of improving the overall response to abuse cases, reduces the cost for handling them, and facilitates the work of all the people involved in the operation of the Internet.

 

b. Arguments Opposing the Proposal

RIPE NCC members have to verify and update (if required) their abuse-c objects periodically.

 

c. Alignment with other RIRs: RIRs

A similar proposal has been accepted in APNIC (being implemented) APNIC, abandoned in ARIN and is under discussion in the LACNIC, LACNIC and AFRINIC and ARIN regions.

Abstract

This policy originated from the work of the Abuse Contact Management Task Force. The task force examined the collection and maintenance of resource registration information in the RIPE Database, including potential areas for improvement and alternative approaches.

This policy introduces a new contact attribute named "abuse-c:”, that can be included in  inetnum inet6num  and  aut-num  objects.

1.0 Abuse Contact Information

The "abuse-c:" will reference a role object holding abuse contact information. The positioning of the “abuse-c:” attributes will make use of the hierarchical nature of the resource data to minimize the workload on resource holders. Internet number resources need to have an “abuse-c:” attribute.

The “abuse-c:” will be mandatory for all  aut-num s.

Due the hierarchical nature of IP address objects, at least every direct allocated  inetnum  and  inet6num  needs to have an “abuse-c:”. Inherited objects might have their own “abuse-c:” attribute or they will be covered by the higher level objects.

The role objects used for abuse contact information will be required to contain a single “abuse-mailbox:” attribute which is intended for receiving automatic and manual reports about abusive behavior originating in the resource holders' networks.

The “abuse-mailbox:” attribute must be available in an unrestricted way via whois, APIs and future techniques.

The RIPE NCC will validate the “abuse-mailbox:” attribute at least annually. Where the attribute is deemed incorrect, it will follow up in compliance with relevant RIPE Policies and RIPE NCC procedures. 

As per current practice, other "e-mail:" attributes can be included for any other purposes.
