Dear All,

ICANN announced the publication of a paper describing the methodology used in the Domain Abuse Activity Reporting (DAAR) system and two reviews of that methodology.

DAAR was designed to provide the ICANN community with a reliable, persistent, and reproducible data from which security threat (abuse) analyses could be performed.

The DAAR project has produced a system for studying and reporting domain name registration and security threat (domain abuse) behavior across top-level domain (TLD) registries and registrars. The overarching purpose of DAAR is to report security threat activity as it is experienced in network operations to the ICANN community, which can then use the data to facilitate informed policy decisions.

To inform the community of the DAAR project design objectives and the ways by which those objectives have been met, the ICANN organization has prepared a methodology white paper. The paper explains the purposes of the DAAR project and gives an overview of the system, describes the security threats that DAAR observes, and how DAAR compiles threat data from high-confidence threat reputation data feeds.

To foster confidence in the DAAR system, the ICANN org has engaged two independent experts to review the methodology paper, to comment on the threat data that DAAR consumes, and to experiment with the reporting system. The purpose of these reviews is to have experts in the field validate the methodology, attest to the reproducibility of DAAR's findings and reporting, and to attest to the quality and reliability of the reputation data that the ICANN org has chosen to use for this project.

We welcome your comments on the reports and reviews. Please send them to daar@icann.org, by 24 August 2018. The findings and recommendations from the reviewers and parties who comment will be considered in the final drafting of the methodology paper.

Best regards,
