8.6 Role-Based Access Control

Title
Role-Based Access Control
Control
Authorization of identities enrolled in a PACS is viewed as separate from cardholder authentication. PACS may grant access only to cardholders who were enrolled and authorized in the PACS Server prior to presenting their credentials for authentication, or they may make on- the-fly access control decisions by evaluating the information on presented PIV Cards against a set of access control rules. Because PIV Cards contain only a few mandatory subject attributes (just the Agency Code, Employee Affiliation, and Investigation Status Indicator) that may be used for role-based access control, role or group permissions will usually be derived from off- card information. In the future, standardized role information may be available on-card, especially for Emergency Response Officials or Continuity of Operations (COOP) procedures. Recommendation: Because having on-card role and permission information would raise difficult challenges concerning update and revocation, PACS permissions should generally be stored in a PACS facilities-based component, such as a panel or controller database.
