IA-9 SERVICE IDENTIFICATION AND AUTHENTICATION

The organization identifies and authenticates [Assignment: organization-defined information system services] using [Assignment: organization-defined security safeguards].

SUPPLEMENTAL GUIDANCE

This control supports service-oriented architectures and other distributed architectural approaches requiring the identification and authentication of information system services. In such architectures, external services often appear dynamically. Therefore, information systems should be able to determine in a dynamic manner, if external providers and associated services are authentic. Safeguards implemented by organizational information systems to validate provider and service authenticity include, for example, information or code signing, provenance graphs, and/or electronic signatures indicating or including the sources of services.

RELATED CONTROLS: IA-9 (2)

CONTROL ENHANCEMENTS

IA-9 (1) SERVICE IDENTIFICATION AND AUTHENTICATION | INFORMATION EXCHANGE

The organization ensures that service providers receive, validate, and transmit identification and authentication information.

Supplemental Guidance: NONE

IA-9 (2) SERVICE IDENTIFICATION AND AUTHENTICATION | TRANSMISSION OF DECISIONS

The organization ensures that identification and authentication decisions are transmitted between [Assignment: organization-defined services] consistent with organizational policies.

Supplemental Guidance:

For distributed architectures (e.g., service-oriented architectures), the decisions regarding the validation of identification and authentication claims may be made by services separate from the services acting on those decisions. In such situations, it is necessary to provide the identification and authentication decisions (as opposed to the actual identifiers and authenticators) to the services that need to act on those decisions.
