| === What is OpenVAS? ===
| |
| [https://www.openvas.org/ OpenVAS] is an 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 works. I also found it very intuitive to work with.
| |
| | |
| So without further ado, let’s dive right into the installation.
| |
| | |
| '''OpenVAS''', an endpoint scanning application and web application used to identify and detect vulnerabilities. It is widely used by companies as part of their risk mitigation solutions to quickly identify gaps in their production and even development servers or applications. This is not a complete solution, but it can help you fix common security vulnerabilities that may not be discovered.
| |
| | |
| The condition of Greenbone mode is open (APEVALV) from infected chemistry (GVM) of the quality of the storage and the GitHub area. it is used in the Greenbone Security Manager device and is a comprehensive scan. An engine that runs an advanced and constantly updated Network Vulnerability Test Package (NVT).

| == OpenVAS Usage Examples ==
| |
| Before trying to do anything with OpenVAS, you must first run the setup script, appropriately named openvas-setup. At the end of the (very long) setup process, the automatically created password will be displayed to you. '''Save the password somewhere safe'''.

| ; After the setup completes, you will find two listening TCP ports: 9390 and 9392
| |
| Port 9392 is likely the one of most interest to you as it is the web interface for OpenVAS. You can open the web interface using your browser of choice.
| |

| |
| | |
| Despite reminding people to save the default password generated during setup, it still sometimes gets misplaced. Fortunately, the “openvasmd” utility can be used to create and remove users as well as reset their passwords.
| |
| | |
| root@kali:~# openvasmd --create-user=dookie
| |
| User created with password 'yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyy'.

| OpenVAS signatures can be updated with the “openvas-feed-update” utility.
