This document is not intended to be a walk-through of the user interface; hence, the implementation of security from a user interface perspective will not be outlined. For those who will be upgrading servers from SQL Server version 7.0 and earlier, information that explains the security part of the upgrade is provided, as well as notes for those who are knowledgeable in the way security was handled in SQL Server 6.5 and earlier. Many developers and administrators successfully implemented the security architecture in SQL Server version 7.0 and earlier; however, those who took security seriously were aware that the improvements to security could only be applied as patches until a more thorough integration was possible. SQL Server 2000 builds on the security features in SQL Server 7.0 and provides an improved security solution over those offered with SQL Server 6.5 and earlier.
