What is an example of denial of service in cloud security?

Denial of service (DoS) in cloud security refers to an attack that aims to make a service unavailable to its intended users. This involves overwhelming the service with traffic or exploiting vulnerabilities that cause the service to become unresponsive. The correct choice highlights loss of service availability as a direct consequence of such attacks. When a cloud service is targeted and its availability is disrupted, users can no longer access the resources or applications they need, which can have significant implications for businesses relying on these services.

In the context of cloud security, ensuring service availability is critical for maintaining user trust and operational continuity. A denial of service can severely impact performance, leading to downtime and potential financial losses. This makes it a serious threat that organizations must prepare for to ensure their systems remain operational and accessible.
