NIST SP 800-171 R2 Identifiers are provided for users, processes acting on behalf of users, or devices (IA.L2-3.5.1). Preventing reuse of identifiers implies preventing the assignment of previously used individual, group, role, or device identifiers to different individuals, groups, roles, or devices.
