Tenable Vulnerability Management Logs

Connecting Tenable Vulnerability Management logs in your Panther Console

Overview

Panther supports pulling vulnerability logs directly from Tenable.

How to onboard Tenable Vulnerability Management logs to Panther

To onboard Tenable logs, you will generate an API key in Tenable, then set up a source in Panther.

Step 1: Create an API key in Tenable

1. Log in to Tenable.

2. Click Settings > My Account.

3. Click API Keys > Generate > Continue.

   • Make note of your access key and secret key, as you will use them in the next step.

Step 2: Create a Tenable Log Source in Panther

1. In the left-side navigation bar of your Panther Console, click Configure > Log Sources.

2. Click Create New.

3. Search for "Tenable Nessus," then click its tile.

4. In the slide-out panel, click Start Setup.
5. Enter a descriptive name, then click Setup.

6. Enter the Access Key and Secret Key you generated in the previous step.

7. Click Setup. You will be directed to a success screen:

   

   • You can optionally enable one or more Detection Packs.

   • The Trigger an alert when no events are processed setting defaults to YES. We recommend leaving this enabled, as you will be alerted if data stops flowing from the log source after a certain period of time. The timeframe is configurable, with a default of 24 hours.
