This rule may cause medium to high performance impact due to scoping all remote Windows logon activity within the first sequence. This rule by default will be noisy if not scoped to custom privileged accounts. If noisy, duplicate the rule and replace the `TargetUserName` or `TargetSid` filters with your own naming convention and accounts of interest.
