Which of the following is MOST important for an IS auditor to confirm upon learning that an organization utilizes storage virtualization for key systems in their environment?
A.
Restoration testing is performed at regular intervals.
B.
Redundancy is included in the storage architecture.
C.
Backup drives are available at the disaster recovery hot site.
D.
Access to physical media is limited to authorized individuals.
The correct answer is B, Redundancy is included in the storage architecture.
Storage virtualization is a technique that allows an organization to create a virtualized storage environment by pooling together physical storage resources from multiple devices into a single logical storage unit. This can provide benefits such as increased storage capacity, improved storage utilization, and easier management of storage resources. However, it is important for an IS auditor to confirm that redundancy is included in the storage architecture to ensure that the virtualized storage environment is resilient and can continue to function in the event of a hardware failure or other disruption.
While the other options (A, C, and D) are also important considerations for an IS auditor, they are not as directly related to the integrity and availability of data in a storage virtualization environment as redundancy. Restoration testing (Option A) is important but assumes that redundancy is already in place. Backup drives at a disaster recovery site (Option C) are important for disaster recovery, but they don't specifically address the real-time availability of data in the primary environment. Access control to physical media (Option D) is important for security, but it doesn't address the potential data availability concerns introduced by storage virtualization.
When an organization utilizes storage virtualization for key systems, the most important consideration for an IS auditor to confirm is whether redundancy is included in the storage architecture. Storage virtualization involves abstracting physical storage resources and presenting them as logical entities. Redundancy in the storage architecture is critical to ensure data availability and continuity in the event of hardware failures or other disruptions.
Confirming the inclusion of redundancy in the storage architecture is key when assessing the impact of storage virtualization on the availability and resilience of key systems.
