A vulnerability scanner tool is used to scan a network or system for a list of predefined
vulnerabilities such as system misconfiguration, outdated software, or a lack of patching, they will
not detect viruses or malware unless it has opened ports that shouldn't be and even then it would
just list the port as open. It is very important to understand the output from a vulnerability scan,
they can be 100's of pages for some systems, and how do the vulnerabilities map to Threats and Risks
(Risk = Threat x Vulnerability).
