IA-04 [H] Identifier Management

Control

Manage system identifiers by:
  1. Receiving authorization from [Assignement: personnel or roles] to assign an individual, group, role, service, or device identifier;
  2. Selecting an identifier that identifies an individual, group, role, service, or device;
  3. Assigning the identifier to the intended individual, group, role, service, or device; and
  4. Preventing reuse of identifiers for [Assignement: time period].

Discussion

Common device identifiers include Media Access Control (MAC) addresses, Internet Protocol (IP) addresses, or device-unique token identifiers. The management of individual identifiers is not applicable to shared system accounts. Typically, individual identifiers are the usernames of the system accounts assigned to those individuals. In such instances, the account management activities of [AC-2](#ac-2) use account names provided by [IA-4](#ia-4) . Identifier management also addresses individual identifiers not necessarily associated with system accounts. Preventing the reuse of identifiers implies preventing the assignment of previously used individual, group, role, service, or device identifiers to different individuals, groups, roles, services, or devices.

Assessment Objective

  1. system identifiers are managed by receiving authorization from [Assignement: personnel or roles] to assign to an individual, group, role, or device identifier;

  3. system identifiers are managed by assigning the identifier to the intended individual, group, role, service, or device;
  4. system identifiers are managed by preventing reuse of identifiers for [Assignement: time period].

IA-04(04) [H] Identify User Status

Control

Manage individual identifiers by uniquely identifying each individual as [Assignement: characteristics].

Discussion

Characteristics that identify the status of individuals include contractors, foreign nationals, and non-organizational users. Identifying the status of individuals by these characteristics provides additional information about the people with whom organizational personnel are communicating. For example, it might be useful for a government employee to know that one of the individuals on an email message is a contractor.
