A company is conducting a pre-migration risk assessment for moving its sensitive intellectual property (IP) to a multi-tenant public cloud. The assessment reveals that the cloud provider uses shared underlying infrastructure for multiple customers. What is the MOST significant privacy concern arising from this multi-tenant architecture for the company's sensitive IP?
- AIncreased latency when accessing the IP data.
- BChallenges in integrating with on-premises legacy systems.
- CDifficulty in achieving high availability for the IP data.
- DRisk of data commingling or unauthorized access due to logical separation failures.
Show answer & explanationAnswer & explanation
Correct answer: D. Risk of data commingling or unauthorized access due to logical separation failures.
In a multi-tenant environment, the primary privacy concern for sensitive data like IP is the potential for data commingling or unauthorized access. While logical separation mechanisms are in place, a failure in these controls could expose one customer's data to another, posing a significant privacy and confidentiality risk.
Why the other options are wrong
- A. Increased latency is a performance concern, not a direct privacy concern related to multi-tenancy.
- B. Integration challenges are an operational/technical concern, not a direct privacy concern related to multi-tenancy.
- C. High availability is an operational concern, not a direct privacy concern related to multi-tenancy.
Multi-Tenancy Privacy Risk
Multi-tenancy in cloud computing, where multiple customers share the same underlying physical infrastructure, introduces privacy risks primarily related to the potential for data commingling, side-channel attacks, or unauthorized access if logical separation mechanisms fail or are compromised.
- Shared physical resources among multiple customers.
- Relies on strong logical isolation mechanisms.
- Primary risk: data leakage or unauthorized access between tenants.
Memory trick: Shared cloud means shared risks if separation fails.
