What does "cloud security" involve?

Cloud security involves a comprehensive set of services and measures that are specifically designed to safeguard data and applications within cloud computing environments. This means protecting cloud data from unauthorized access, ensuring confidentiality, integrity, and availability, and mitigating risks associated with cloud storage and processing.

The correct answer highlights that cloud security is not limited to a single aspect but encompasses multiple protective measures, including identity and access management, data encryption, compliance, and monitoring mechanisms to defend against threats in a shared cloud environment. This is critical, as many organizations now rely heavily on cloud-based services for their operations and must ensure that sensitive information is adequately protected in the cloud.

In contrast, protecting data only on local servers addresses a different realm of security that does not account for the unique vulnerabilities of cloud-based infrastructures. Network firewalls in cloud infrastructure represent only one component of a broader security strategy, while temporary storage methods do not encompass the range of necessary protective measures that cloud security requires.
