Version 1.2.0

  • Initial Release

About this release

Version 1.2.0 of Aplura Vulnerabilities App for Splunk is compatible with:

Splunk Enterprise versions 7.0, 7.1
Platforms Splunk Enterprise

Overview

This app provides Splunk dashboards, forms, and reports which can be used to explore your vulnerability events, and make sense of what can often be a large volume of data.

To do this, the app relies on the Splunk Common Information Model (CIM) for vulnerability events. This means that the app can report on any vulnerability data, as long as it has been on-boarded properly, and is available through the Vulnerabilities data model.

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 vulnerability 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

Overview

This dashboard serves as a jumping-off point for exploring your vulnerability data. It includes panels for vulnerabilities over time, severities, destinations, and signatures. Clicking on panels in this dashboard will drill down to the appropriate profile page for further exploration.

Severity Profile

Form with reports and visualizations built around a set of severities (Critical, High, Medium, Low, Informational, Unknown, or all).

Dest Profile

Form with reports and visualizations built around a destination (host or IP address, depending on how your CIM information for your vulnerability management events is mapped).

Signature Profile

Form with reports and visualizations built around a signature, such as Terminal Services Encryption Level is Medium or Low or Buffer overrun in NT kernel message handling. Note that this is different than a CVE number, this is the text description of the vulnerability.

Vulnerability Search

Form with many input variables. This is a flexible form designed to help generate a knockout list for fixing a set, or particular type of vulnerability.

Identifier Search

Form for searching based on an identifier for a vulnerability, such as CVE, Cert, MSFT, or other reference number.

Prerequisites

Splunk Versions

This app has been tested with Splunk versions 7.0 and 7.1. This app should be installed on the same search head on which the |data_model| 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 |data_model| 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 Vulnerability 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 |data_model| data model must be accelerated. Information on how to enable acceleration for the |data_model| 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 |data_model| data model has been accelerated. More information on installing or upgrading Splunk apps can be found here.

Simple Installation Process

  • Make sure the field extractions and tags on your vulnerability events are correct.
  • Install the Splunk Common Information Model Add-on (skip if you are installing on an ES search head).
  • Install the Aplura Vulnerabilities App for Splunk for Splunk.
  • Enable accelerations on the |data_model| data model (skip if you are installing on an ES search head).
  • Wait for the accelerations to start. After the acceleration searches have run, you should start seeing the dashboards populate.

Macros for Configuration

This app uses the following macros which can be used for customization:

vuln_show_severity

This macro can be used to make the app use a less strict approach to the CIM. The CIM defines what valid values for severity. If your data does not follow this, you can use this for adding other definitions.
