Hotspot Question
A security analyst performs various types of vulnerability scans. You must review the vulnerability scan results to determine the type of scan that was executed and determine if a false positive occurred for each device.
Instructions:
Select the drop option for whether the results were generated from a credentialed scan, non- credentialed scan, or a compliance scan.
For ONLY the credentialed and non-credentialed scans, evaluate the results for false positives and check the findings that display false positives.
NOTE: If you would like to uncheck an option that is currently selected, click on the option a second time. Lastly, based on the vulnerability scan results, identify the type of Server by dragging the Server to the results.
The Linux Web Server, File-Print Server and Directory Server are draggable. If at any time you would like to bring back the initial state of the simulation, please select the Reset button. When you have completed the simulation, please select the Done button to submit. Once the simulation is submitted, please select the Next button to continue.
