What is row level security in SQL?

Contents show

With SQL Server 2016, the feature known as row-level security (RLS) was added. It restricts and filters a table’s row-level data in accordance with security policies specified by the user rather than encrypting or decrypting a database’s table data. This gives the database engine the ability to restrict the number of rows of exposed data.

Can data masking be reversed?

Data masking, tokenization, and encryption all function differently. Both encryption and tokenization are reversible because it is possible to deduce the original values from the obfuscated data. On the other hand, if data masking is carried out correctly, it is irreversible.
