Internal Vulnerability Scanning on macOS: Manual Set-up

This article describes how to manually install the agent on a Linux device. If you wish to individually install the agent on your devices, you can use the installation wizard inside the platform.

🚨 IMPORTANT 🚨

For each agent that you install, you must have a license available; if you don't, the machine(s) won't show up on your targets page.

👉 If you're installing the agent on 10 machines, you must have 10 licenses available.

Step 1: Download the agent installer

Head to the Nessus agent download page:
https://www.tenable.com/downloads/nessus-agents

Search for the relevant .dmg installer file (i.e. NessusAgent-X.X.X.dmg) and download it.

Step 2: Install the agent

Double-click on the .dmg file and then double-click the "Install Nessus Agent.pkg" installer.

Step 3: Configure your linking command

Open the Targets page > Add Targets > Internal targets

Click 'View configuration keys'

Copy the 'Prefix' and 'Key'

Assemble your name. It's comprised of your Prefix and your DeviceName
(what you'd like the target to be named in the portal).
👇
eg. DQEGBQUAAAc_paul-laptop
Populate the command below with your name and KEY

sudo /Library/NessusAgent/run/sbin/nessuscli agent link --name=[Prefix_DeviceName] --cloud --key=[KEY]

Step 4: Link the agent to Intruder

Open the Terminal app
Run the linking command you created above
If you see a prompt for a password, enter your computer's password and hit return. (Don't worry that you can't see any of the characters that you're typing – this is normal).

When the linking command has run successfully, you'll see this 👇 :

It'll take between 5-10 minutes for the system to show on your targets page and voila. (...assuming you have licenses available that is).
