Selective Scan Instructions Using Qualys

To perform a selective vulnerability scan, configure a scan profile to use the following options:

  1. Ensure access to TCP ports 135 and 139 are available.
  2. Enable Windows Authentication (specify Authentication Records).
  3. Enable the following Qualys IDs:
    • 100346
    • 110325
    • 91478
    • 91479
    • 91480
    • 91481
    • 91482
  4. If you would like the scan to return the Windows Hostname, also include QID 82044 and ensure access to UDP port 137 is available.
  5. If you would like to be notified if Qualys is unable to log on to a host (if Authentication fails), also include QID 105015.

In addition, prior to running a scan for these new vulnerabilities, you can estimate your exposure to these new threats by running the Risk Analysis Report, available from the Qualys Vulnerability Management Reports tab.
