Intrusion App for Splunk

Overview

Many organizations is IDS/IPS devices and software as their first line of defense against attackers. This app provides Splunk dashboards, forms, and reports which can be used to explore your IDS events across your different sourcetypes.

To do this, the app relies on the Splunk Common Information Model (CIM) for IDS attack events. This means that the app can report on any authentication data, as long as it has been on-boarded properly, and is available through the Intrusion Detection data model, including network, host, wireless, and application products.

A note on Splunk Data Model Acceleration and Disk Space

This app requires data model acceleration, which will use additional disk space. If you are using the Splunk App for Enterprise Security, this is already enabled, and should have been factored into your retention policies. If not, you should review the documentation on data model acceleration, how it uses disk space, and how to plan for it.

A note on the Splunk Common Information Model

As mentioned above, the app uses the CIM for authentication events. The CIM allows you to take events from a number of sources or products, and report on them in one cohesive manner, using a common set of names for fields and event types.

Available Dashboards

Intrusion Overview

Provides a starting point for exploring your IDS events. Most panels will drill-down to other pages in the application.

Attack Source Profile

A view based on the source of IDS events.

Attack Destination Profile

IDS events where attacks are launched against the same destination.

Attack Signature Profile

Panels which focus on events which all are from the same identified with the same signature.

Attack Category Profile

A view focusing on attacks which fall into the same category (as defined in the events).

Attack Search

A form for finding events based on various field values.

Sourcetypes (Advanced)

Information about the sourcetypes which are present in the accelerated data.

Prerequisites

Splunk Versions

This app has been tested with Splunk versions 6.6. This app should be installed on the same search head on which the Authentication data model has been accelerated.

Splunk Common Information Model Add-on

This app depends on data models included in the Splunk Common Information Model Add-on, specifically the "Authentication" data model. Please review the information on installing and using the Splunk Common Information Model Add-on and information on configuring the acceleration on the data model.

The Splunk Common Information Model Add-on can be downloaded from Splunkbase.

This app has been tested with versions 4.9 of the CIM add-on.

Data model Acceleration on the Intrusion data model

In order to make the app respond and load quickly, accelerated data models are used to provide summary data. For this data to be available, the Intrusion Detection data model must be accelerated. Information on how to enable acceleration for the Intrusion Detection data model can be found here. The data model must be accelerated for the length of time for which you would like to see reporting.

Installation

This app should be installed on a search head where the Intrusion Detection data model has been accelerated. More information on installing or upgrading Splunk apps can be found here.

Simple Installation Process

  1. Make sure the field extractions and tags on your authentication events are correct.
  2. Install the Splunk Common Information Model Add-on (skip if you are installing on an ES search head).
  3. Install the Intrusion App for Splunk.
  4. Enable accelerations on the Intrusion Detection data model (skip if you are installing on an ES search head).
  5. Wait for the accelerations to start. After the acceleration searches have run, you should start seeing the dashboards populate.

About support for this app
