Nessus Scanner User Information
Nessus is a network-based vulnerability scanner that can connect to a network service, collect information about that service, and then compare the collected service information against known vulnerabilities.
...
In addition to identifying services that contain known vulnerabilities, Nessus can help you find unnecessary services, and services that may be necessary but which are inadvertently open to the Internet (e.g., you may need MySQL, but you probably don't need it to be accessible from the internet). We encourage the use of vulnerability scanning in all production server, application, and host deployments.
