DNSDB

The Security Challenge

Cybercriminals quickly exploit Internet infrastructure to support their campaigns and avoid detection.

Security teams need to “turn back the clock” to view Internet infrastructure as it was at a certain point in time to see how adversaries have “rolled” through related domains, IP addresses and name servers to conceal their activity.

Security analysts and incident responders need access to real-time and historical Passive Domain Name System data in order to block their infrastructure from being used by bad actors. A historical view of Passive DNS data also enables security teams to detect patterns of malicious activity and identify phishing or other targeted attacks.

The Farsight Solution

DNSDB

A Must-Have Tool for Today’s Security Teams

Farsight Security’s DNSDB™ is a Passive DNS historical 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’s DNSDB is a bridge to new data points in all of our investigations.”

Rich Barger
Chief Intelligence Officer

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 Passive DNS data service of its kind - with more than 35 billion DNS resolutions since 2010.

Farsight’s DNSDB transforms threat feeds into actionable, relevant threat intelligence in real time to increase the value of an organization’s existing threat intelligence. Its high-performance, indexed, time-series DNS intelligence data service can ultimately improve visibility for an organization’s security program and protect its infrastructure from current and future threats.

How Does It Work?

Security teams can map out related domains, IP addresses, and infrastructure for thorough investigation and protection.

With DNSDB, security, incident response, SOC and research teams can:

Accelerate incident research and post-breach analysis.
Discover associations among threat actors and track and block their activity.
Perform fact-based risk assessment of domain names and IP addresses.
Uncover all domains using the same name server infrastructure used by a “known bad” domain.
Reveal the IPs an adversary is using to conceal malicious activity and avoid takedowns.
Conduct third-party audits of DNS configurations.

Farsight’s DNSDB is built for ease of use. Chain and pivot capabilities allow security teams to easily swing from one query to another. Time fencing, output tailoring and limiting of record types are among the capabilities that enable investigators to access the exact results they need. DNSDB queries can be automated into existing workflows through a RESTful API, web-enabled UI and integration with security incident and event management solutions, security automation solutions and threat intelligence platforms.
