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.

Configure DNSDB v2 in Cortex

Parameter Description Required
apikey API Key True
url DNSDB Service URL False
insecure Trust any certificate (not secure) False
useproxy Use system proxy settings False

Commands

You can execute these commands from the CLI, as part of an automation, or in a playbook.
After you successfully execute a command, a DBot message appears in the War Room with the command details.

dnsdb-flex

DNSDB flex search

Base Command

dnsdb-flex

Input

Argument Name Description Required
method query value type Required
key search over rrnames or rdata Required
value query regex or glob Required
rrtype query rrtype Optional
limit Limit the number of returned records Optional
time_first_before Filter results for entries seen for first time before (ISO or UNIX timestamp, relative if negative) Optional
time_last_before Filter results for entries seen for last time before (ISO or UNIX timestamp, relative if negative) Optional

Context Output

Path Type Description
DNSDB.Record.RRName string The owner name of the resource record in DNS presentation format.
DNSDB.Record.RRType string The resource record type of the resource record, either using the standard DNS type mnemonic, or an RFC 3597 generic type, i.e. the string TYPE immediately followed by the decimal RRtype number.
     
DNSDB.Record.RData string The record data value. The Rdata value is converted to the standard presentation format based on the rrtype value. If the encoder lacks a type-specific presentation format for the resource record’s type, then the RFC 3597 generic Rdata encoding will be used.
     
DNSDB.Record.Count number The number of times the resource record was observed via passive DNS replication.
DNSDB.Record.TimeFirst date The first time that the resource record was observed.
DNSDB.Record.TimeLast date The most recent time that the resource record was observed.
DNSDB.Record.FromZoneFile bool False if the resource record was observed via passive DNS replication, True if by zone file import.

dnsdb-rate-limit

Retrieve service limits

Base Command

dnsdb-rate-limit

Input

There are no input arguments for this command.

Context Output

| Path | Type | Description |
| — | — | — |
| DNSDB.Rate.Limit | number | The maximum number of API lookups that may be performed. This is the initial quota. |
| DNSDB.Rate.Unlimited | bool | True if there is no maximum number of API lookups that may be performed. |
| DNSDB.Rate.Remaining | number | For time-based quotas: the remaining number of API lookups that may be performed until the reset time.
For block-based quotas: the remaining number of API lookups in the block quota.
|
| DNSDB.Rate.Reset | date | For time-based quotas: When the quota limit will be reset. Usually this is at 00:00 (midnight) UTC.
|
| DNSDB.Rate.NeverResets | bool | True for block-based quotas that do not reset. |
| DNSDB.Rate.Expires | date | Only present for block-based quota. When the quota will expire. |
| DNSDB.Rate.ResultsMax | number | The maximum number of results that can be returned by these lookup methods. This overrides a “limit” query parameter if provided. For example, if “?limit=20000” is appended to the URL path but results_max=1000 then only up to 1000 results will be returned.
|
| DNSDB.Rate.OffsetMax | number | The maximum value that the offset query parameter can be. If it is higher then an HTTP 416 “Requested Range Not Satisfiable” response code will be returned with message “Error: offset value greater than maximum allowed.”
