May I know about the details information about the "Unknown" Operating System detected by Qualys? I mean which network devices is detect as "Unknown" by Qualys Appliances. Please help!
Hi Sanjoy, if you will run query:
NOT operatingSystem: (* .. *)
in Asset Search tab you will get list of all assets for which Qualys cannot determine OS. In my cases those are mostly Web apps and appliances, but I am doing authenticated scans for most of my assets.
Hope that helps,
