In order to support Early Alert with No Vulnerability Scan technology in NormShield, after installing the NormShield agent through NormShield HotPoint, configuration settings under Service Scan tab should be adjusted.
This settings, when enabled, will scan only open ports of target systems defined through NormShield portal and try to find CPEs (Common Platform Enumeration items) in order to match them with CVEs (Common Vulnerability Enumeration items).
Enable Service Scan checkbox should be selected for activating the feature. Nmap is used for detail service scanning and scan parameters can be adjusted at one's leisure.
After everything is good, don't forget to hit the SAVE button.
