Ensure 'Hide Instance' option is set to 'Yes' for Production SQL Server instances
Опис
Non-clustered SQL Server instances within production environments should be designated as hidden to prevent advertisement by the SQL Server Browser service. Designating production SQL Server instances as hidden leads to a more secure installation because they cannot be enumerated. However, clustered instances may break if this option is selected.
