CCI-003321 Definition

Require the developer of the system, system component, or system service to produce, as an integral part of the development process, an informal descriptive top-level specification that specifies the interfaces to security-relevant hardware in terms of exceptions, error messages, and effects.

Master Assessment Datasheet

Implementation Guidance

The organization being inspected/assessed documents within the contracts/agreements, the requirement that the developer of the information system, system component, or information system service produce, as an integral part of the development process, an informal descriptive top-level specification that specifies the interfaces to security-relevant hardware in terms of exceptions, error messages, and effects.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the contracts/agreements to ensure the organization being inspected/assessed requires that the developer of the information system, system component, or information system service produce, as an integral part of the development process, an informal descriptive top-level specification that specifies the interfaces to security-relevant hardware in terms of exceptions, error messages, and effects.

Compelling Evidence

1.) System security plan (SSP). 2.) System development life cycle (SDLC) documentation. 3.) Continuous monitoring plan requiring the developers of the information system, system component, or information system service to produce, as an integral part of the development process, an informal descriptive top-level specification that specifies the interfaces to security-relevant hardware in terms of exceptions, error messages, and effects.
