Security policy with QDBusServer

[magrif]

Hello everyone.
I'm start new QDBusServer on tcp socket

QDBusServer{"tcp:host=localhost,bind=*,port=10050,family=ipv4"}

I'm can connect from remote machine only with

setAnonymousAuthenticationAllowed(true)

using QDBusConnection::connectToPeer

How/where to compose security policy for p2p connection, like for session or system bus connections? I'ts possible?
Thanks!
