OS detection in passive deployment

tfellinger

Hello,

I have here a passive deployment of a FirePower Appliance. Unfortunately there are around 40 hosts which get tagged as ESX Servers...which is not correct. Are there ways to optimize the OS detection? I know of NMAP scans, are there other options I can activate to make this feature work better?

 

Thanks!

Hi, Did you manage to resolve this issue and how?

Hi,

not really...it kind of ended in setting the OS manually for these hosts. Probably ýou can achieve better automatic results by placing a sensor more close to the client, but this was not an option in my case.
