As important as security is, remaining current with every development is hard, and evaluating possible vulnerabilities across a network can be quite a chore. You need a way to both automate tests and make sure you're running the most appropriate and up-to-date tests. Open Vulnerability Assessment System (OpenVAS) is a network security scanner that includes a central server and a graphical front end. The server allows you to run several different network vulnerability tests (NVT) written in Nessus Attack Scripting Language (NASL), which OpenVAS updates frequently.
