Business Continuity: Definition, Planning, and Compliance
Business Continuity
Business continuity refers to an organization's ability to maintain essential functions during and after a disruption — whether that disruption is a cyberattack, natural disaster, infrastructure failure, or pandemic. A business continuity plan (BCP) documents how the organization will respond to, recover from, and resume normal operations after such events.
Key Components of a Business Continuity Plan
- Business impact analysis (BIA) — Identifies critical business functions and the impact of their disruption over time
- Recovery time objectives (RTO) — The maximum acceptable downtime for each critical function
- Recovery point objectives (RPO) — The maximum acceptable data loss measured in time
- Recovery strategies — Specific procedures for restoring operations (failover systems, backup restoration, alternate sites)
- Communication plan — How stakeholders, customers, and employees will be notified during an incident
- Testing schedule — Regular exercises to validate the plan works as documented
Why It Matters
ISO 27001 Annex A includes controls for information security continuity (A.5.29 and A.5.30) and ICT readiness for business continuity (A.8.14). Auditors verify that business continuity plans exist, are tested, and are maintained.
SOC 2 Availability criteria directly address whether an organization can maintain system availability during disruptive events. Auditors review disaster recovery capabilities, backup procedures, and testing evidence.
HIPAA requires covered entities to have a contingency plan that includes data backup, disaster recovery, and emergency mode operations.
Common Mistakes
Writing the plan but never testing it. A business continuity plan that has never been tested provides false assurance. Tabletop exercises, simulation tests, and full failover tests should be conducted at least annually.
Ignoring dependencies. Critical business functions often depend on third-party services, specific personnel, or infrastructure that may also be affected by the same disruption. Map dependencies thoroughly.
Treating it as an IT project. Business continuity spans the entire organization. It requires input from operations, legal, HR, and executive leadership — not just the technology team.
