What aspect of cloud security does resiliency primarily address?

Resiliency in cloud security primarily addresses data recovery in the event of a failure. This aspect is crucial because it ensures that data is protected and can be restored after incidents such as hardware malfunctions, cyberattacks, or natural disasters. Having robust data recovery processes and mechanisms in place helps organizations minimize downtime and loss of critical information, enabling them to maintain business continuity even after disruptions occur. This aligns with the broader concept of resiliency, which focuses on the ability of systems to recover quickly and effectively, thus maintaining the integrity and availability of data.

While the other aspects listed are significant in the context of cloud operations, they do not directly relate to the definition of resiliency. Scalability refers to the ability to adjust resources according to demand, user access levels pertain to the permissions granted to users, and physical hardware upkeep addresses the maintenance of physical systems rather than the recovery of data after an incident. Hence, the focus on data recovery is what distinctly characterizes the aspect of resiliency in cloud security.
