4611: A trusted logon process has been registered with the Local Security Authority

On this page

An occurrence of event 4611 is logged at startup and occasionally afterwards for each logon process on the system.

A logon process is a trusted part of the operating system and handles the overall logon function for different logon methods including incoming RAS connections, RunAs, interactive logons initiated by CtrlAltDel, and network logons (as in drive mappings).

Because logon processes are such trusted functions, a rogue logon process would be a devastating security breach--but an improbable one, given the effort and skill required.
