After SolarWinds is installed, up and running, Many companies need harden the Windows server, SQL server.
How about SolarWinds itself (for all modules)?
is there any hardening reference that SolarWinds use??
I haven't seen it all in one place but in the admin guide there are ports listed for communication through a firewall and depending on the services you have enabled then you would need those ports open as well 22,162,161,514...
