Disaster recovery standards are the formal frameworks that tell an organization how to prepare for, respond to, and recover from disruptions, from a single failed server to a hurricane that closes a whole facility. The most widely used are ISO 22301 for business continuity management, ISO/IEC 27031 for the underlying IT readiness, NIST SP 800-34 for federal information systems, and NFPA 1660 for emergency and crisis management. Regulated industries stack their own mandatory obligations on top: HIPAA contingency planning in healthcare, FINRA Rule 4370 for broker-dealers, and SEC cybersecurity disclosure for public companies.
ISO 22301: The International Business Continuity Standard
Organizations looking for a globally recognized framework usually start with ISO 22301, published in 2019. It sets out the requirements for building and maintaining a Business Continuity Management System that fits inside an organization’s existing structure.1International Organization for Standardization. ISO 22301:2019 – Security and Resilience — Business Continuity Management Systems — Requirements The standard is deliberately flexible and shapes itself around your legal environment, industry, size, and stakeholder expectations.2International Organization for Standardization. ISO 22301:2019 – Security and Resilience — Business Continuity Management Systems — Requirements
What separates ISO 22301 from an informal plan is its insistence on continuous improvement. Senior leadership must actively sponsor the program with dedicated budget and personnel. The system requires regular testing, documented reviews, and updates whenever operations or the risk picture change. That plan-test-revise cycle is the backbone of the standard and what auditors examine during certification.
ISO/IEC 27031: IT Readiness Underneath the Management System
Where ISO 22301 governs the management program, ISO/IEC 27031 addresses the technology layer that has to actually deliver recovery. It focuses on making sure information and communications infrastructure can support continuity when something fails.3ISO. ISO/IEC 27031 – Information Technology — Security Techniques — Guidelines for Information and Communication Technology Readiness for Business Continuity Its scope includes fault-tolerant system design, redundant telecommunications and power sources, and data protection measures during the recovery phase itself.
One update to watch: the original 2011 edition has been withdrawn and replaced by ISO/IEC 27031:2025. Organizations previously aligned with the 2011 version need to review their technical controls against the revised edition. The standard applies to organizations of any size or type, including government agencies, and functions as the technical companion to broader management frameworks like ISO 22301.
NIST SP 800-34: Federal Contingency Planning
Federal agencies and the contractors supporting them operate under NIST Special Publication 800-34, the government’s guide to information system contingency planning.4Computer Security Resource Center. NIST SP 800-34 Rev. 1 – Contingency Planning Guide for Federal Information Systems This isn’t optional guidance. The Federal Information Security Modernization Act requires agencies to comply with NIST standards, and the Government Accountability Office uses them as benchmarks when auditing agency security programs.5National Institute of Standards and Technology. FISMA Background – NIST Risk Management Framework
NIST SP 800-34 scales its requirements to the sensitivity of the system involved. Systems fall into low, moderate, and high impact categories, and each tier carries different expectations for testing, backups, and recovery:
- Low-impact systems generally need only a tabletop exercise at a defined frequency. Alternate processing sites and backup testing beyond basic procedures are not required.
- Moderate-impact systems require functional exercises that include recovering from backup media, and backup information must be tested to confirm it actually works.
- High-impact systems require full-scale exercises including failover to an alternate location, recovery from backup at a separate facility, and complete reconstitution to a known secure state. Systems supporting continuity-of-operations functions must be recoverable within 12 hours.6National Institute of Standards and Technology. NIST SP 800-34 Rev. 1 – Contingency Planning Guide for Federal Information Systems
Contractors handling federal data face real consequences for falling short. Losing the contract is the most immediate risk, and financial penalties for non-compliance are also on the table. If your organization touches federal systems, map each one to the correct impact level and build the recovery plan around the corresponding NIST requirements.
FedRAMP for Cloud Providers
Cloud service providers seeking federal work must also meet FedRAMP’s recovery planning requirements. As of 2026, FedRAMP evaluates providers against Key Security Indicators that include aligning backups with recovery objectives, maintaining and testing recovery plans, and persistently reviewing recovery time and recovery point targets.7FedRAMP. Recovery Planning – FedRAMP Documentation These sit on top of the NIST framework, so cloud providers effectively satisfy both.
NFPA 1660: Emergency, Continuity, and Crisis Management
Organizations that run large physical facilities, deal with public safety, or coordinate with local emergency responders should know NFPA 1660. First published in 2023, it consolidated three previously separate standards into one document: NFPA 1600 (continuity and emergency management), NFPA 1616 (mass evacuation, sheltering, and re-entry), and NFPA 1620 (pre-incident planning).8National Fire Protection Association. NFPA 1660, Standard for Emergency, Continuity, and Crisis Management: Preparedness, Response, and Recovery
The consolidation was substantive, not cosmetic. The old NFPA 1600 backbone remains (program management, risk assessment, impact analysis, training, and improvement cycles), but NFPA 1660 formalizes two areas that were previously loose or optional. First, organizations must now document how each site functions during an incident, including building layout, utility systems, known hazards, and protection systems like sprinklers and alarms. Second, evacuation, sheltering, and re-entry procedures are now mandatory program elements with standardized terminology and explicit documentation requirements.9National Fire Protection Association. What Is the New NFPA 1660
If your program was aligned with NFPA 1600, the transition means reviewing existing documentation against the expanded site-function and evacuation requirements.
Industry-Specific Mandatory Requirements
The frameworks above set the baseline. Several industries face additional requirements that carry regulatory enforcement, not just voluntary adoption.
Healthcare: HIPAA Contingency Planning
Any organization handling electronic protected health information must comply with the HIPAA Security Rule’s contingency planning requirements under 45 CFR § 164.308(a)(7).10eCFR. 45 CFR 164.308 – Administrative Safeguards The regulation breaks contingency planning into five components:
- A data backup plan that creates and maintains viable copies of all electronic protected health information so records can be restored if the originals are lost or destroyed.
- A disaster recovery plan with written procedures for restoring access to data after an emergency, including step-by-step instructions for restoring files from backups. A copy of this plan must be stored in more than one location.
- Emergency mode operations procedures for keeping critical business processes running during technical failures or power outages while still protecting patient data.
- Testing and revision, with plans regularly tested through walkthroughs and live exercises, then revised based on what the tests reveal.
- Application and data criticality analysis, an assessment of which applications and data sets are most critical, used to prioritize what gets restored first.
Plans should account for a range of foreseeable disruptions, from natural disasters and fires to cyberattacks and ransomware. HIPAA auditors look for documentation proving you’ve actually tested your recovery procedures, not just written them down.
Financial Services: FINRA Rule 4370
Broker-dealers registered with FINRA must maintain a written business continuity plan under Rule 4370. The plan must cover data backup and recovery, all mission-critical systems, alternate communications with customers and employees, alternate physical locations, and how customers will access their funds and securities if the firm can’t continue operating.11FINRA. 4370. Business Continuity Plans and Emergency Contact Information
Firms must conduct an annual review and update the plan after any material change to operations, structure, or location. A registered principal in senior management must approve the plan and own the annual review. Firms must also register two emergency contact persons with FINRA through the FINRA Contact System, at least one of whom must be a senior management member who is a registered principal.11FINRA. 4370. Business Continuity Plans and Emergency Contact Information
There is a customer-facing element too. Firms must disclose how their continuity plan addresses significant disruptions. At a minimum, this summary must be provided in writing at account opening and posted on the firm’s website.12FINRA. Business Continuity Planning FAQ
Public Companies: SEC Cybersecurity Disclosure
Publicly traded companies face a disclosure obligation that ties directly to disaster recovery. Under SEC Form 8-K Item 1.05, a company that experiences a cybersecurity incident it determines to be material must file a disclosure within four business days of that determination.13U.S. Securities and Exchange Commission. Form 8-K The filing must describe the nature, scope, and timing of the incident, along with its material or reasonably likely material impact on the company’s financial condition and operations.14Federal Register. Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure
There is no fixed dollar threshold for materiality. The SEC uses a reasonable-investor test: if a reasonable investor would consider the incident important when making investment decisions, it is material. An incident causing significant reputational harm or customer impact can trigger the disclosure even without a large direct financial loss. The only exception to the four-day deadline is a written determination from the U.S. Attorney General that immediate disclosure would pose a substantial risk to national security or public safety.
The Planning Elements Every Framework Depends On
Whichever standard applies, the same foundational analyses show up in every disaster recovery program. Without them, a recovery plan is a collection of good intentions that falls apart under pressure.
Business Impact Analysis
A business impact analysis identifies which functions are most sensitive to downtime and quantifies what it costs when those functions stop. This is where organizations often discover that a back-office billing system is more critical than the customer-facing portal everyone worried about. The analysis forces honest conversations about priorities, and those priorities drive every recovery decision that follows.
Recovery Time and Recovery Point Objectives
Two metrics anchor every recovery plan. The recovery time objective is the maximum duration a system can be offline before the business impact becomes unacceptable. The recovery point objective defines how much data loss you can tolerate, measured as the gap between your last usable backup and the moment of disruption. A recovery point objective of four hours means you accept losing up to four hours of data; a recovery point objective of zero means you need real-time replication.
These are not numbers you pick from a menu. They come from the business impact analysis and they determine how much you need to spend on infrastructure. Shorter objectives demand more expensive solutions like synchronous data mirroring and hot standby sites. Longer objectives let you get by with nightly backups and cold recovery.
Risk Assessment
A risk assessment evaluates the likelihood and potential impact of specific threats. Threats vary by industry and geography. A data center in a flood zone faces different risks than a trading firm worried about ransomware. The assessment feeds into your recovery strategy by identifying which scenarios deserve the most investment and which ones you accept as low-probability enough to handle with basic measures.
Testing and Keeping Plans Current
Every major framework treats disaster recovery as a cycle, not a project. Plans that sit in a binder for three years become dangerous because they create false confidence. Infrastructure changes, staff turn over, vendors get acquired, and threats evolve. A plan that assumes a decommissioned server room is still active will fail exactly when needed.
At minimum, review recovery plans annually and run exercises that test real recovery procedures rather than just walking through a checklist. FINRA requires the annual review explicitly. HIPAA mandates testing and revision. NIST SP 800-34 scales testing frequency to system impact levels. Even without a specific regulatory mandate, the annual-review-plus-exercise cadence is what auditors, insurers, and sophisticated clients expect. Update plans immediately after any material change: a new office location, a migration to a different cloud provider, or an acquisition that brings new systems into scope.
