OpenVAS is a free vulnerability scanner and it is a forked version of the last free Nessus code on github after it was closed sourced in 2005. For its plugins, it still uses the same NASL Language of Nessus. It’s a free, Open Source and powerful network vulnerability scanner.
If you are using OpenVAS for the first time then you need to auto-configure it using the following command. It’ll configure openvas service and generate a user and its password.
