An IS auditor is reviewing the disaster recovery testing program for a financial services firm. The firm has successfully conducted several structured walk-throughs and has validated its data backup and restoration procedures. Management now wants to gain a higher level of assurance that critical business processes can operate effectively at the alternate site without impacting live production systems. Which type of test should the IS auditor recommend as the MOST appropriate next step?
Worked Example: Auditing a Restoration Test
Scenario: An IS auditor is reviewing the quarterly restoration test for a financial services firm's critical customer database. The firm's disaster recovery plan (DRP) specifies a Recovery Time Objective (RTO) of 2 hours.
- Step 1: Review the Plan and Backup Logs The auditor confirms the RTO is 2 hours. The backup strategy is a full backup on Sunday and differential backups Monday-Saturday. The backup logs show all jobs completed successfully this week.
- Step 2: Observe the Restoration Test The IT team initiates a restoration of the latest full backup and the most recent differential backup to a segregated test environment. The auditor times the process from initiation to the moment the database is online and verified as consistent.
- Step 3: Analyze the Results The data is restored successfully and is uncorrupted. However, the entire process took 3 hours and 15 minutes.
- Step 4: Formulate the Audit Finding The key finding is not that the backup worked, but that the recovery process failed to meet business requirements. The finding should be stated as: "The restoration test for the critical customer database exceeded the documented 2-hour RTO by 75 minutes. While data was recoverable, the current process does not support the organization's business continuity requirements, posing a risk of extended operational disruption."
Common ISACA CISA Distractors on ISACA · CISA4-B
- 1Use this framework to dissect any CISA question about backup controls:
- 2Step 1. Identify the Business Requirement. The first thing to look for in the scenario is the stated Recovery Time Objective (RTO) and Recovery Point Objective (RPO). These are the non-negotiable business requirements that define control success.
- 3Step 2. Evaluate the Backup Strategy against the RPO. Does the backup frequency and type support the maximum data loss tolerance? A 24-hour RPO requires, at a minimum, daily backups. An RPO of 1 hour requires much more frequent snapshots or replication.
- 4To remember the restoration process:
- 5INCREMENTAL = IN-creasingly complex. You need the full backup plus all the in-between incremental backups in the correct sequence.
