Views and Security
A popular, but controversial, method to design security is to create a view that exposes only certain columns, or that restricts the rows with a WHERE clause and a WITH Check Option, and then grants permission to the view to allow users limited access to data. Some IT shops require that all access goes through such a view.
Those opposed to using views for a point of security have several good reasons:
- Views are not compiled or optimized.
- Column-level security can be applied with user-defined SQL Server security.
- Using views for row-level security means that the WITH CHECK OPTION must be manually created with each view. As the number of row-level categories grows, it can become cumbersome to do this type of manual maintenance.
