Which risk is controlled by implementing a private cloud?

Implementing a private cloud primarily addresses physical security risks. In a private cloud environment, the infrastructure is dedicated to a single organization, allowing for greater control over the physical aspects of security. Organizations can establish stringent access controls to the physical hardware, such as data centers, servers, and networking equipment, which are not shared with other entities.

Since private clouds reduce the likelihood of shared physical spaces, organizations can more effectively manage who has access to their facilities, implement surveillance measures, and enforce physical security protocols tailored to their specific needs. This tight control can prevent unauthorized individuals from physically accessing the hardware used to store sensitive data, thus significantly enhancing the overall security posture.

The other risks, such as eavesdropping, unauthorized access, and denial-of-service (DoS) attacks, can be influenced by the cloud environment but are not directly addressed by the physical containment offered by a private cloud. These risks often require additional technical and procedural controls, such as encryption for data in transit, robust authentication mechanisms, and network security measures. Therefore, the implementation of a private cloud is most closely aligned with enhancing physical security compared to the other listed risks.
