03.05.03E Device Attestation

Statement

Handle device identification and authentication based on attestation by {{ insert: param, A.03.05.03E.ODP.01 }}.

Guidance

Device attestation refers to the identification and authentication of a device based on its configuration and known operating state. Device attestation can be determined via a cryptographic hash of the device. If device attestation is the means of identification and authentication, then it is important that patches and updates to the device are handled via a configuration management process such that the patches and updates are done securely and do not disrupt identification and authentication to other devices. This requirement enhances SP 800-171 requirement 03.05.02.

Statement

• (includes preempt) Ensure that the threat event does not have an impact.

  • Reduce likelihood of occurrence and/or reduce likelihood of impact.

  • The adversary’s efforts or resources cannot be applied or are wasted.

• (includes exert) Make it more difficult for threat events to cause adverse impacts or consequences.

  • Reduce likelihood of impact and reduce level of impact.

  • Adversary activities are restricted in scope, fail to achieve full effect, do not take place in accordance with adversary timeline, or require greater resources than adversary had planned.

• (includes detect) Reduce risk due to ignorance of threat events and possible replicated or similar threat events in the same or similar environments.

  • Reduce likelihood of impact.

  • The adversary loses the advantage of stealth as defenders are better prepared by developing and sharing threat intelligence.
