OpenVAS: Open Vulnerability Assessment System

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. The actual security scanner is accompanied with a daily updated feed of Network Vulnerability Tests, over 19,000 in total (as of November 2010). All OpenVAS products are Free Software.


The core of this SSL-secured service-oriented architecture is the OpenVAS Scanner. The scanner very efficiently executes the actual Network Vulnerability Tests which are served with daily updates via the 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. The OpenVAS Administrator acts as a command line tool or as a full service daemon. The most important tasks are the user management and feed management.
