The Open Vulnerability Assessment System (OpenVAS) is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution




Architecture Overview


The Open Vulnerability Assessment System (OpenVAS) is a framework of several services and tools. The core of this SSL-secured service-oriented architecture is the OpenVAS Scanner. The scanner very efficiently executes the actual Network Vulnerability Tests (NVTs) which are served with daily updates Openvas NVT Feed or via a commercial feed service.







The OpenVAS Manager is the central service that consolidates plain vulnerability scanning into a full vulnerability management solution. The Manager controls the Scanner via OTP (OpenVAS Transfer Protocol) and itself offers the XML-based, stateless OpenVAS Management Protocol (OMP). All intelligence is implemented in the Manager so that it is possible to implement various lean clients that will behave consistently e.g. with regard to filtering or sorting scan results. The Manager also controls a SQL database (sqlite-based) where all configuration and scan result data is centrally stored.



A couple of different OMP clients are available: The Greenbone Security Assistant (GSA) is a lean web service offering a user interface for web browsers. GSA uses XSL transformation stylesheet that converts OMP responses into HTML.



The Greenbone Security Desktop (GSD) is a Qt-based desktop client for OMP. It runs on various Linux, Windows and other operating systems.


OpenVAS CLI contains the command line tool “omp”  which allows to create batch processes to drive OpenVAS Manager.


The OpenVAS Administrator acts as a command line tool or as a full service daemon offering the OpenVAS Administration Protocol (OAP). The most important tasks are the user management and feed management. GSA support OAP and users with the role “Admin” can access the OAP functionality.


Most of the tools listed above share functionality that is aggregated in the OpenVAS Libraries.


The OpenVAS Scanner offers the communication protocol OTP (OpenVAS Transfer Protocol) which allows to control the scan execution. This protocol is subject to be eventually replaced and thus it is not recommended to develop OTP clients. Traditionally, the desktop- and cli-tool OpenVAS Client acts as a direct OTP client.

Update your Vulnerability Database Feeds

Administration > NVT Feed > Synchronise with Feed Now


Nvt feedThis step is critical.  if you do not update the vulnerability database feeds, it will generate errors later on.

Like wise update all below field in admin panel

Administration > NVT Feed

Administration  > SCAP Database Feed (these are xml files for the reports)

Administration > Cert Feed

Set Targets to Scan


Configuration > Targets

Localhost will be there by default.


Add your router as a target eg



Look for the Blue box with a White star  click the  star

White star = New Target

New target Enter IP of Router, and port options (eg all TCP)

Create Target Button
