Remote PowerShell Session (PS Classic)
This rule detects the initiation of a remote PowerShell session by looking for specific strings in PowerShell Classic logs. Specifically, it identifies events where 'HostName=ServerRemoteHost' and 'wsmprovhost.exe' are present in the log data, indicating that a remote host is interacting via Windows Remote Management (WinRM) to execute PowerShell commands.
