ISO 27001 Annex A 5.30: ICT readiness for business continuity

What Control 5.30 means in practice

Align technology recovery capability with prioritized business needs and test that it works. Test the control through the organisation's actual scope, decisions, ownership and operating records rather than relying on a policy reference alone.

For ict readiness for business continuity, proportional design depends on the affected services, information, people and dependencies. The evidence below should be adapted to that real boundary.

Implementation steps

1. Step 1. Define ownership, scope and operating criteria for ict readiness for business continuity.
2. Step 2. Implement continuity arrangement that fits the organization’s risks, services and working practices.
3. Step 3. Integrate the activity with relevant change, exception and review processes.
4. Step 4. Review performance and improve the arrangement when risks, technology or obligations change.

What good implementation looks like

• successful recovery tests measured against objectives
• failed steps and dependency gaps remediated
• current recovery procedures proven by people other than their authors

Implementation evidence and effectiveness evidence

How an auditor may test Control 5.30

1. Select a representative in-scope service, asset or process.
2. Confirm the accountable owner and expected operation.
3. Trace a recent example: A critical customer service has agreed recovery time and recovery point objectives.
4. Inspect the operating record and corroborating technical evidence.
5. Compare the design with evidence that the control operated effectively.
6. Follow an exception or adverse result through decision and closure.
7. Review trends, metrics and improvement decisions.

Questions to prepare for

• How is ict readiness for business continuity implemented in practice?
• Who owns the activity and how are decisions approved?
• Show me a recent example from operation through review.
• How are exceptions, changes or overdue actions handled?

Practical examples

Illustrative decision and evidence record

Reviewer note: Test ict readiness for business continuity with a recent real example; a current operating record normally reveals more than policy wording alone.

Useful performance and coverage measures

• recovery tests meeting objectives
• restore failures and repeat defects
• critical dependencies without tested recovery

Approach for smaller and mature organizations

Smaller organization

Use a clear owner, a proportionate working record, built-in platform capability and a scheduled review. Sample real activity instead of creating duplicate paperwork for ict readiness for business continuity.

Mature or complex organization

Define service-level ownership, automated coverage reporting, integrated workflow, risk-based exceptions and independent assurance across business units and technology platforms.

Practical implementation checklist

• □ Define ownership, scope and operating criteria for ict readiness for business continuity.
• □ Implement continuity arrangement that fits the organization’s risks, services and working practices.
• □ Integrate the activity with relevant change, exception and review processes.
• □ Review performance and improve the arrangement when risks, technology or obligations change.
• □ Sample evidence has been checked for operation and effectiveness.
• □ Exceptions have owners, rationale, review dates and closure evidence.

Common implementation mistakes

• documenting ict readiness for business continuity without consistent operation
• unclear ownership or review frequency
• evidence that does not cover the full ISMS scope
• exceptions accepted without risk-based approval or follow-up
