Row-Level Security let us control access to data at row level for any SQL Server table based on users, roles, membership or working context. It tremendously simplifies and improve the options we have to secure, filter, implement restrictions or eventually deal with our data over certain scenarios. What is most relevant for me is that all the security policy can be set centrally at a database level preventing developers from taking care of adding custom where clauses to enforce security. It makes the management of data much more reliable and maintainable.

Here is a link to the meetup we held in the dotNetters community some months ago. IT was amazing for me to talk about such an interesting subjects :)
