From Visual Access Control:
Powerful Access Control tools for ASP.net that would further support your goal to deliver business grade software development solutions. The tools consist of role driven Module Access Security and Data Access Security controls and provide enhanced access security over the standard ASP.net membership and role providers: The Module Access Security controls enable you to define granular permissions at the application level thus providing your client with a higher level of manageability over the application. Data Access Security controls further empower your client to dynamically restrict the users to a subset of the data based on their respective roles and areas of responsibilities. This is an ideal solution when trying to meet regulatory requirements (i.e. HIPAA, SOX, ISO ...) or business needs such as a geographically disbursed business environment where different users need to be restricted to the activities they are allowed to perform and to the subset of data they are permitted to see.
