Farsight DNSDB v2
This Integration is part of the Farsight DNSDB Pack.#
Farsight Security DNSDB#
Farsight Security DNSDB® is the world’s largest DNS intelligence database that provides a unique, fact-based, multifaceted view of the configuration of the global Internet infrastructure. DNSDB leverages the richness of Farsight’s Security Information Exchange (SIE) data-sharing platform and is engineered and operated by leading DNS experts. Farsight collects Passive DNS data from its global sensor array. It then filters and verifies the DNS transactions before inserting them into the DNSDB, along with ICANN-sponsored zone file access download data. The end result is the highest-quality and most comprehensive DNS intelligence data service of its kind - with more than 100 billion DNS records since 2010.
This integration uses Farsight Security’s DNSDB solution to interactively lookup rich, historical DNS information – either as playbook tasks or through API calls in the War Room – to access rdata and rrset records. It was integrated and tested with version 2 of the DNSDB API.
