Security

There are two aspects of database security, object security and authentication. Object security refers to the process of determining whether or not a user who has access to the database is authorized to access particular database objects. Authentication refers to the process of determining whether or not a user is authorized to access (in other words, connect to) the database. Both object security and authentication use the concept of database groups or roles to ensure security. This section first describes the group concept, then describes how the LN MSQL driver authenticates and provides object security.
