Which factor is essential for ensuring compliance in cloud security?

Comprehensive service-level agreements (SLAs) play a vital role in ensuring compliance in cloud security. SLAs define the expectations between service providers and clients regarding the level of service, performance metrics, and responsibilities for security and compliance. These agreements formalize the commitments the cloud provider makes about data handling, incident response, and compliance with relevant regulations, such as GDPR or HIPAA. By establishing clear expectations and accountability in the SLA, organizations can better ensure that their cloud service providers adhere to compliance requirements, thereby mitigating risks associated with security breaches and ensuring that legal and regulatory obligations are met.

Other options might not directly contribute to compliance. For instance, broad network access relates more to the accessibility of services rather than compliance itself. Non-redundant systems can present risks to availability and resiliency, which are essential for security but do not specifically address compliance concerns. Minimal oversight could lead to gaps in compliance, as it suggests a lack of governance and monitoring, which are crucial to ensure that compliance requirements are continuously met.
