Security and Protection
An enterprise business solution must have a built-in security system that helps protect your database and the information that it contains from unauthorized access. It must also allow you to specify what authorized users are allowed to do in the database, such as what data they can read and modify.
Microsoft Dynamics NAV 2015 provides a security system that allows administrators to manage user access to the objects and data in the Microsoft Dynamics NAV database. Because the Microsoft Dynamics NAV database is on SQL Server, the Microsoft Dynamics NAV security system and SQL Server security system work together to help ensure that only authorized users can gain access to the Microsoft Dynamics NAV database.
Much additional information relating to security can be found in the Administration in the RoleTailored Client node under Administration. See in particular:
