Infoblox DDI

Overview

Infoblox DNS, DHCP and IP address management (DDI) enables customer to control and automate their network. It performs both of the main DNS server roles, acting as an authoritative name server for domains, and acting as a recursive resolver in the network.

Benefit from SEKOIA.IO built-in rules and upgrade Infoblox DDI with the following detection capabilities out-of-the-box.

SEKOIA.IO x Infoblox DDI on ATT&CK Navigator

SEKOIA.IO Intelligence Feed

Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.

Configure

In this guide, you will configure the gateway to forward events to syslog.

Prerequisites

An internal log concentrator (Rsyslog) is required to collect and forward events to SEKOIA.IO.

Enable Syslog forwarding

Log on your NIOS appliance and follow this guide to enable syslog forwarding

Create the intake

Go to the intake page and create a new intake from the format Infoblox DDI.

Transport to SEKOIA.IO

Please consult the Rsyslog Transport documentation to forward these logs to SEKOIA.IO.
