IA.L1-3.5.2 — Device Identification and Authentication

Devices that require unique device-to-device identification and authentication are defined by type, device, or a combination of type and device. Organization-defined device types include devices that are not owned by the organization. Systems use shared known information (e.g., Media Access Control .MAC, Transmission Control Protocol/Internet Protocol .TCP/IP addresses) for device identification or organizational authentication solutions (e.g., Institute of Electrical and Electronics Engineers .IEEE 802.1x and Extensible Authentication Protocol .EAP, RADIUS server with EAP-Transport Layer Security .TLS authentication, Kerberos) to identify and authenticate devices on local and wide area networks. Public Key Infrastructure (PKI) and certificate revocation checking for the certificates exchanged can be included as part of device authentication.
