What is NIST SP 800-34 used for?

• A. Contingency planning for information technology systems.
• B. A guide for mapping types of information and information systems to security categories.
• C. A guide for security certification and accreditation of federal information systems.
• D. A guide for developing security plans for federal information systems.

Answer: (A)

Contingency planning for information technology systems. This area focuses on preparing for, responding to, and recovering from disruptions to IT services so that essential operations can continue and data can be restored quickly. NIST SP 800-34 lays out a structured approach: identify critical systems and dependencies, set recovery objectives (like how quickly systems must be back up and what data loss is acceptable), select recovery strategies, and define procedures for activating, testing, and maintaining the contingency plan. It emphasizes the entire lifecycle of continuity—from policy and planning to testing and updates—so organizations can minimize downtime and impact during incidents.

The other topics map to different guides: mapping information to security categories is about determining impact levels for information and systems; certification and accreditation is the formal authorization process for systems’ security controls; developing security plans is about documenting security controls and responsibilities. Each of those serves a different facet of security and risk management, whereas SP 800-34 specifically targets continuity and recovery planning.
