ISO 22301:2019
Security and Resilience — Business Continuity Management Systems — Requirements
ISO 22301:2019 specifies management system requirements to protect against, reduce the likelihood of, and ensure recovery from disruptive incidents. It establishes structured Business Impact Analysis (BIA), Maximum Tolerable Period of Disruption (MTPD), Recovery Time Objectives (RTO), Recovery Point Objectives (RPO), and mandatory rehearsed incident exercise programs across cloud outages, cyberattacks, and physical crises.
Scope & Applicability
All organizations, regardless of size or industry, requiring verified operational resilience to continue delivering essential products and services during major disruptions.
Non-Coverage Boundaries
Does not prescribe specific IT disaster recovery architectures (like multi-region Kubernetes vs cold backups); it evaluates organizational continuity policies, response teams, and verified recovery metrics.
Key Clauses & Control Requirements
Clause 8.2.2: Business Impact Analysis (BIA)
Systematic assessment of disruption impacts over time to determine prioritized activities, dependencies, RTO, and RPO.
Clause 8.4: Business Continuity Plans & Procedures
Documented action procedures detailing emergency response, immediate incident containment, command escalation, and step-by-step restoration.
Clause 8.5: Exercise and Testing Programme
Mandatory regular simulation exercises (tabletop, technical failover, unannounced tests) validating that continuity arrangements function as designed.
Required Regulatory & Audit Evidence Artifacts
- [✓]Enterprise Business Impact Analysis (BIA) Register with defined RTO and RPO per critical service
- [✓]Business Continuity Plan (BCP) and Disaster Recovery Plan (DRP) runbooks
- [✓]Annual Disaster Recovery failover drill report with timestamped logs and post-exercise corrective action items
“A disaster recovery plan that has never been tested in a live simulation is not a plan; it is a creative writing exercise. ISO 22301 forces organizations to turn hypothetical recovery into verified muscle memory.”

Frequently Asked Questions
What is the difference between RTO and RPO in ISO 22301?
RTO (Recovery Time Objective) is the maximum acceptable duration of system downtime before service restoration. RPO (Recovery Point Objective) is the maximum acceptable age of data lost due to a disruption.
