Why do we need vulnerability assessment?

The overall objective of a vulnerability assessment is to scan, investigate, analyze, and report on the severity of risks associated with any vulnerabilities discovered on the external facing resource. It should also provide your organization with an appropriate mitigation plan to address the weaknesses or vulnerabilities previously discovered. Network vulnerability scanning can help an organization to identify weaknesses in their network security. Whether results are good or bad will depend on who runs the scanning first - a system admin or attackers.
