What is OpenVas?
OpenVAS (Open Vulnerability Assessment System) is a software framework of several services and tools offering vulnerability scanning and vulnerability management, free software, and most components are licensed under the GNU General Public License (GPL). Plugins for Open VAS are written in the Nessus Attack Scripting Language, NASL.
OpenVAS – Open Vulnerability Assessment Scanner
The scanner is accompanied by a vulnerability tests feed with a long history and daily updates. This Greenbone Community Feed includes more than 80,000 vulnerability tests.
The scanner is developed and maintained by Greenbone Networks since 2009. The works are contributed as Open Source to the community under the GNU General Public License (GNU GPL).
n 2019 the branding separation was completed. OpenVAS now represents the actual vulnerability scanner as it did originally and the “S” in “Open VAS” now stands for “Scanner” rather than “System”. These changes are accompanied by an updated OpenVAS logo. The framework where OpenVAS is embedded is the Greenbone Vulnerability Management (GVM).
Open VAS released with GVM-10 receives numerous performance optimization to address the challenge of a growing number of vulnerability tests, scanning target networks of increasing size and heterogeneity.
Open VAS released with GVM-11 introduces substantial architectural changes: The former service “openvassd” is turned into a command line tool “openvas”. It is controlled by the service layer ospd-openvas. This concept essentially replaces the old stateful, permanent and proprietry OTP (OpenVAS Transfer Protocol) by the new state-less, request-response XML-based and generic OSP (Open Scanner Protocol).
