Discussion (NIST Supplemental Guidance)

Organizations consider the potential mission or business impact in situations where telecommunications service providers are servicing other organizations with similar priority of service provisions. Telecommunications Service Priority (TSP) is a Federal Communications Commission (FCC) program that directs telecommunications service providers (e.g., wireline and wireless phone companies) to give preferential treatment to users enrolled in the program when they need to add new lines or have their lines restored following a disruption of service, regardless of the cause. The FCC sets the rules and policies for the TSP program, and the Department of Homeland Security manages the TSP program. The TSP program is always in effect and not contingent on a major disaster or attack taking place. Federal sponsorship is required to enroll in the TSP program.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for CP-8(1) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. primary telecommunications service agreements that contain priority-of-service provisions in accordance with availability requirements (including recovery time objectives) are developed;
  2. alternate telecommunications service agreements that contain priority-of-service provisions in accordance with availability requirements (including recovery time objectives) are developed;
  3. Telecommunications Service Priority is requested for all telecommunications services used for national security emergency preparedness if the primary and/or alternate telecommunications services are provided by a common carrier.

Examine

[SELECT FROM: Contingency planning policy; procedures addressing primary and alternate telecommunications services; contingency plan; primary and alternate telecommunications service agreements; Telecommunications Service Priority documentation; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with contingency plan telecommunications responsibilities; organizational personnel with system recovery responsibilities; organizational personnel with information security responsibilities; organizational personnel with responsibility for acquisitions/contractual agreements].

Test

[SELECT FROM: Mechanisms supporting telecommunications].
