What is Dynamic Data Masking?

The title is quite revealing, is it not?

Dynamic Data Masking which is available in SQL Server 2016 allows you provide another level of security to your data, by masking data that you do not want unauthorized (by policies) users to peek into. Data in the database itself is unchanged. SQL Server 2016 has other security features besides dynamic data masking.

This is a nice feature that you should implement if are dealing with sensitive information (Credit card numbers, Social Security Numbers, etc).

Here is an image of credit card numbers being masked

Do you need special permission to create a table with a dynamic data mask?

No, you do not. Of course you need standard permissions like Create table, Alter on schema permissions.

The Alter Any Mask permission and Alter permission on  a Table are needed, though.
