We covered how to use OpenVas vulnerability scanner to scan for vulnerabilities. OpenVAS, an application used to scan endpoints and web applications to identify and detect vulnerabilities. It is commonly used by corporations as part of their mitigation solutions to quickly identify any gaps in their production or even development servers or applications. This was part of TryHackMe OpenVas room.

From the OpenVAS GitHub repository “This is the Open Vulnerability Assessment Scanner (OpenVAS) of the Greenbone Vulnerability Management (GVM) Solution. It is used for the Greenbone Security Manager appliances and is a full-featured scan engine that executes a continuously updated and extended feed of Network Vulnerability Tests (NVTs).”

OpenVAS is a service within a larger framework of services known as Greenbone Vulnerability Management (GVM). In this task we will break down the services that make up the framework and their roles.

OpenVas Installation

Option 1: Install from Kali/OpenVAS repositories

Installing from repositories can sometimes be very simple or it can be a very painful process. For OpenVAS, the installation ranges in difficulty and can require many configurations ran. For more information about this option check out the guides below.



Option 2: Install from Source

Installing from source is the least preferred option for beginners and the least optimized way of installing OpenVAS due to prerequisites and make errors. For more information about installing from source look at the INSTALL.MD.

Option 3: Run from Docker (Preferred)

Docker is by far the easiest of all three installation methods and only requires one command to be run to get the client started. For this installation procedure, you will need docker installed.

1. apt install docker.io

2. docker run -d -p 443:443 --name openvas mikesplain/openvas
