How to install OpenVAS on ParrotSec

I show you how to install OpenVAS on ParrotSec in a step-by-step tutorial.

What is OpenVAS?

OpenVAS is THE open source vulnerability scanner. OpenVAS started under the name of GNessUs, a fork of the previously open-source Nessus scanning tool (which costs you money now). OpenVAS is also under the GNU General Public License (GPL).

I personally used this software in many different kinds of assessments and was always satisfied with the results I got (keeping in mind that it is completely free).

Of course tools like Nessus and NeXpose are more feature-rich, but they come with a high price-tag too.

For starters, OpenVAS is simply perfect and gives you a good idea of how a vulnerability scanner is working. I also found it very intuitive to work with.

So without further ado, let’s dive right into the installation.

I install OpenVAS on a freshly installed ParrotSec in VirtualBox. If you want to know how to install ParrotSec on Virtual Box check out this article.

Navigate to Administration / Users.
