In order to perform a scan correctly, it is equally important to select an apt policy. This will help the user to obtain correct results and saves a lot of time when confirming and reporting the vulnerabilities. For example, if a user wants to know the open ports and he or she goes to perform an advanced scan, he/she will obtain results for configuration audit, patch audit, and many unnecessary plugins which were used in the scan. Instead, if the user had selected a basic network scan, all he/she would find would be open ports and a list of vulnerabilities affecting the services running on those hosts.
