What the auditor wants to verify

Audit objective

Verify that redundancy arrangements are sufficient to meet documented availability requirements and have been tested.

Evidence to request

Evidence Purpose
Availability requirements Shows target availability is defined
BIA/continuity requirements Shows business need and recovery objectives
Redundancy architecture Shows design supports availability
Risk assessment Shows redundancy risks are considered
Failover/recovery test records Shows redundancy works
Actual recovery records Shows real outage performance
Compensating controls Shows gaps are managed
Supplier/cloud resilience evidence Shows third-party redundancy support

Strong evidence

  • Redundancy is linked to RTO/RPO and service criticality.
  • Critical dependencies are included.
  • Failover tests meet target recovery times.
  • Data replication and alternate-site risks are assessed.
  • Gaps have compensating controls and owners.

Weak evidence

  • Cloud or vendor redundancy is assumed without evidence.
  • No availability requirement exists.
  • Failover has never been tested.
  • Standby environment is outdated or insecure.
  • Recovery times exceed requirements without corrective action.

Sample interview questions

  • What availability requirement applies to this service?
  • What redundancy is implemented?
  • When was failover last tested?
  • Which dependencies must also be available?
  • What risks are introduced by replication or alternate locations?

Common nonconformities

  • Redundancy not linked to availability requirements.
  • Failover tests missing or failed without action.
  • Dependencies not included in redundancy design.
  • No risk assessment for replicated data paths.
  • Standby environment not secured or maintained.
