What is the advantage of using roles in DAIS Security?
Linda Gricius (March, 1998): Principals gain access to services by presenting credentials, which contain attributes, and give them access rights to services. These attributes can be assigned to each individual, or to a role. By then allowing a principal to authenticate with a given role, all of the attributes associated with that role are put into the principal’s credentials. So, the use of roles is more efficient when administering principals – rather than having to administer attributes for each principal, you can assign attributes to roles, and then allocate roles to principals.
