How can Qualys calculate the Avg security risk?
The Summary of Vulnerabilities section of the scan report shows the average security risk for all hosts in the report. These factors are used when calculating the average security risk:
• security risk for each host (the highest severity level detected or the average severity level detected, see below)
• number of hosts matching filters (hosts in the report matching the filters set in the scan report template)
Note that the average security risk for the report displays the average for all hosts in the report, and is not affected by the sorting method applied to the Detailed Results section
Hope this helps.
