Updating Nessus


Nessus can be updated either manually, or by scheduling automatic updates. The software update option can be found as a part of the Settings menu. This can be used to schedule daily, weekly, or monthly updates for Nessus software or even just the plugins. By default, Nessus uses its cloud server to download and install the updates, but you can also configure a custom server to download these updates.

Getting ready

You can update Nessus while connected to the internet or offline. If you want a hassle-free update or a quick one, you can ensure that the system is connected to the internet.

However, in order to update Nessus offline, you will have to download the update package from the Nessus website.

How to do it…

Follow these steps:

  1. Navigate to Settings, then Software Update from the home page:
  1. Choose the update frequency: Daily, Weekly, or Monthly.
  2. Provide the server details if you have any internal or external servers from which you want Nessus to fetch updates.
  3. Save the settings...
