  IA-08: Identification and Authentication (Non-Organizational Users)  

base control objective:
The information system uniquely identifies and authenticates non-organizational users (or processes acting on behalf of non-organizational users).

supplemental objective information:
Non-organizational users include all information system users other than organizational users explicitly covered by IA-2. Users are uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization in accordance with AC-14. In accordance with OMB policy and E-Authentication E-Government initiative, authentication of non-organizational users accessing federal information systems may be required to protect federal, proprietary, or privacy-related information. The E-authentication risk assessment is used in determining the authentication needs of non-organizational users based on risks, potential impacts, and required assurance levels. Scalability, practicality, and security issues are simultaneously considered in balancing the need to ensure ease of use for access to federal information and information systems with the need to protect and adequately mitigate risk to organizational operations, organizational assets, individuals, other organizations, and the Nation. Identification and authentication requirements for information system access by organizational users are described in IA-2.

enhancements to the base objective:
