In my article Drag And Drop Role Management with Asp.Net, MVC & jQuery[^] you can see how I check the role the current user has to see if they have the authority to run the action.



During the initialisation of the system you can add the roles into the database by calling a method in the global.asax Application_Start;



Obviously you would do this on the first run just to set things up. Later on you can either comment this out or do some logic checking to see if the roles or user accounts already exist.
