i found this in my event log not sure if im

the source seems potentially dangerous

The service control manager (SCM) is started at system boot. It is a remote procedure call (RPC) server, so that service configuration and service control programs can manipulate services on remote machines.

i looked in the security event log and i cant find any correlation with the login id

The "Source" is what's reporting the event to the event log, not necessarily the cause.

S-1-5-7 is the security ID of an "Anonymous" user, not the Event ID.

Based on the Logon Type (3), it looks like (allowed) anonymous access to a network resource on your computer (like a shared folder, printer, etc.). So no-one is hacking, they are simply using a resource that is allowed to be used by users without logging on with a username/password (AKA: Anonymous).

Find the matching Logon event (probably Event ID 4624) and it's details should tell you where they're logging on from (IP address).

More info on Logon types here.
