IA.L1-3.5.1/b.1.v Identification
Identify information system users, processes acting on behalf of users, or devices.
Source: FAR Clause 52.204-21 b.1.v, NIST SP 800-171 Rev 2 3.5.1
Discussion: Common device identifiers include Media Access Control (MAC), Internet Protocol (IP) addresses, or device-unique token identifiers. Management of individual identifiers is not applicable to shared system accounts. Typically, individual identifiers are the user names associated with the system accounts assigned to those individuals. Organizations may require unique identification of individuals in group accounts or for detailed accountability of individual activity. In addition, this requirement addresses individual identifiers that are not necessarily associated with system accounts. Organizational devices requiring identification may be defined by type, by device, or by a combination of type/device. [SP 800-63-3] provides guidance on digital identities.
Assessment Objectives:
Determine if:
- [a] system users are identified;
- [b] processes acting on behalf of users are identified; and
- [c] devices accessing the system are identified.
Examine: [SELECT FROM: Identification and authentication policy; procedures addressing user identification and authentication; security plan, system design documentation; system configuration settings and associated documentation; system audit logs and records; list of system accounts; other relevant documents or records].
Interview: [SELECT FROM: Personnel with system operations responsibilities; personnel with information security responsibilities; system or network administrators; personnel with account management responsibilities; system developers].
Test: [SELECT FROM: Organizational processes for uniquely identifying and authenticating users; mechanisms supporting or implementing identification and authentication capability].
