CISA Exam Preparation (Question 107)

(107) An IS auditor conducting a review of disaster recovery planning (DRP) at a financial processing organization has discovered the following:
The existing disaster recovery plan was compiled two years earlier by a systems analyst in the organization’s IT department using transaction flow projections from the operations department. The plan was presented to the deputy CEO for approval and formal issue, but it is still awaiting his/her attention.
The plan has never been updated, tested or circulated to key management and staff, though interviews show that each would know what action to take for its area in the event of a disruptive incident.
The basis of an organization’s disaster recovery plan is to reestablish live processing at an alternative site where a similar, but not identical, hardware configuration is already established. An IS auditor should:
A. take no action as the lack of a current plan is the only significant finding.
B. recommend that the hardware configuration at each site is identical.
C. perform a review to verify that the second configuration can support live processing.
D. report that the financial expenditure on the alternative site is wasted without an effective plan.

An IS auditor does not have a finding unless it can be shown that the alternative hardware cannot support the live processing system. Even though the primary finding is the lack of a proven and communicated disaster recovery plan, it is essential that this aspect of recovery is included in the audit. If it is found to be inadequate, the finding will materially support the overall audit opinion. It is certainly not appropriate to take no action at all, leaving this important factor untested. Unless it is shown that the alternative site is inadequate, there can be no comment on the expenditure, even if this is considered a proper comment for the IS auditor to make. Similarly, there is no need for the configurations to be identical. The alternative site could actually exceed the recovery requirements if it is also used for other work, such as other processing or systems development and testing. The only proper course of action at this point would be to find out if the recovery site can actually cope with a recovery.
