Unknown Users Detected In User-IP Mapping

Hi All,

I was checking the User-IP mapping in one of the boxes and noticed something which is a mystery to me. I have attached the picture in this discussion. Some of the entries in the output show as Unknown. Any of you know why and how this happens ?

The white boxes that have been cut out are the usernames which i had to remove due to privacy concerns.

Are these actual users ? Can you look into the traffic logs to see the traffic that is sourced from these ips.

Re: Unknown Users Detected In User-IP Mapping

Hello,

If the firewall/agent is receiving traffic form an ip it does not have user mapping info for, it will probe that ip to get that info. We need to check if the host responds to wmi probes by probing the ip address manually from another host or a host with domain admin login

Following is the command you can run on a cmd, wmic /Node:192.168.128.16 ComptuerSystem Get UserName
