What is OpenVAS?:

OpenVAS (Open Vulnerability Assessment System, originally known as GNessUs) is the scanner component of Greenbone Vulnerability Manager (GVM), a software framework of several services and tools offering vulnerability scanning and vulnerability management.

All Greenbone Vulnerability Manager products are free software, and most components are licensed under the GNU General Public License (GPL). Plugins for Greenbone Vulnerability Manager are written in the Nessus Attack Scripting Language, NASL.

Greenbone Vulnerability Manager began under the name of OpenVAS, and before that the name GNessUs, as a fork of the previously open source Nessus scanning tool, after its developers Tenable Network Security changed it to a proprietary (closed source) license in October 2005. OpenVAS was originally proposed by pentesters at SecuritySpace, discussed with pentesters at Portcullis Computer Security and then announced by Tim Brown on Slashdot.

Greenbone Vulnerability Manager is a member project of Software in the Public Interest. (Source: Wikipedia)

Is OpenVAS free?

Yes, OpenVAS (Open Vulnerability Assessment System) is free and open-source software. It is licensed under the GNU General Public License (GPL) and is available for anyone to download, use, and modify without cost. OpenVAS is widely used for vulnerability scanning and management, providing users with a comprehensive set of tools for identifying and mitigating security vulnerabilities in their systems and networks.

Environment Specification:

We are using a minimal Rocky Linux 9 virtual machine with following specifications.

  • CPU – 3.4 Ghz (2 cores)
  • Memory – 2 GB
  • Storage – 20 GB
  • Operating System – Rocky Linux release 9.1 (Blue Onyx)
  • Hostname – openvas-01.centlinux.com
  • IP Address – 192.168.88.128/24

Prepare your Rocky Linux Server:

Connect with your Rocky Linux server as root using with the help of a ssh client.

Set a Fully Qualified Domain Name (FQDN) for your OpenVAS server by using hostnamectl command.

# hostnamectl set-hostname openvas-01.centlinux.com

Edit /etc/hosts file in a vim text editor.

# vi /etc/hosts

Add following line in this file to setup name resolution.

192.168.88.128 openvas-01.centlinux.com openvas-01

Refresh your Yum cache and update software packages in your Rocky Linux server.

# dnf makecache
# dnf update -y

Sometimes, the above command updates software packages related to Linux Kernel. If his happens then you should reboot your Linux operating system before moving forward with this Linux Tutorial.

# reboot

After restart check the Linux operating system and Linux Kernel versions.

# cat /etc/rocky-release
Rocky Linux release 9.1 (Blue Onyx)

# uname -r
5.14.0-162.12.1.el9_1.0.2.x86_64

OpenVAS requires SELinux to be disabled.

You can execute following sets of commands to permanently disable SELinux in your Rocky Linux server.

# sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config
# grubby --update-kernel ALL --args selinux=0
# reboot

You need to install wget command to download OpenVAS installer.

Execute dnf command to install wget package.

# dnf install -y wget

Install Third Party Yum Repositories:

OpenVAS requires some software packages that are not available in standard yum repositories.

Therefore, you are required to enable CRB (Power Tools) and EPEL (Extra Packages for Enterprise Linux) yum repositories.

You can enable these yum repositories by executing following set of commands.

# dnf config-manager --set-enabled crb
# dnf install -y epel-release epel-next-release

Execute following command to download and install Atomic yum repository.

# wget -q -O - https://updates.atomicorp.com/installers/atomic | sudo sh

  1. I followed your tutorial and successfully got openvas up and running! I'm coming back, a year later, because certain things in openvas have reached their EOL and now i need to update/upgrade Openvas… But i get this error when trying to run dnf upgrade….
