ISC2 CISSP Practice Question

The correct answer is the cloud provider's compliance with relevant security standards and regulations. Compliance with standards like ISO 27001, SOC 2, and industry-specific regulations demonstrates that the provider has implemented appropriate security controls and undergone external validation of their security practices. This is directly relevant to the security of data and applications hosted with the provider and provides assurance that a comprehensive security program is in place.

The provider's data encryption implementation and key management architecture is an important technical security consideration, but it addresses only one specific aspect of cloud security. While encryption is critical for data protection, it doesn't encompass the broader security governance, physical security, network controls, and other elements covered by comprehensive compliance frameworks.

The geographic distribution and redundancy of the provider's data centers primarily addresses availability and resilience rather than security directly. While geographic diversity helps with disaster recovery and business continuity, and sometimes with compliance in data locations. However, it doesn't necessarily indicate stronger security controls or practices at those locations.

The provider's incident response capabilities and security breach notification procedures are important elements of a security program, especially for post-breach management. However, this focuses on how the provider handles security failures rather than their overall security posture and preventive controls. A comprehensive compliance program would include incident response as one of many security requirements.
