Which type of cloud model typically presents the most challenges to a cloud customer during the "destroy" phase of the cloud data lifecycle?
In an IaaS model, cloud customers are responsible for managing the underlying infrastructure components such as virtual machines, storage, and networks. During the 'destroy' phase, customers need to ensure secure data erasure from these components, which can be challenging because it requires direct involvement to verify that data has been completely and securely wiped. This includes handling data in virtual disks, snapshots, and backups, which requires significant effort and technical expertise. Hence, IaaS typically presents the most challenges to a cloud customer during the 'destroy' phase of the cloud data lifecycle.
C. SaaS
The question should say cloud service provider for SAAS to be correct. It currently says cloud customer, why would a cloud customer data pose a problem to a customer that already has access to if even if they opt to destroy it?
However, in the context of the Certified Cloud Security Professional (CCSP) certification, the "destroy" phase of the cloud data lifecycle refers to securely deleting data and ensuring that it is irrecoverable once it is no longer needed. In a SaaS model, customers use applications that are hosted and managed by the cloud service provider. The challenge during the "destroy" phase for SaaS customers is ensuring that their data within the application is properly deleted when it is no longer needed. This includes ensuring that all copies and backups of the data are securely erased to prevent unauthorized access or data leakage. While IaaS customers have direct control over virtualized infrastructure resources, including data storage and virtual machines, securely deleting data in IaaS can be more straightforward compared to SaaS because customers have direct access to the underlying infrastructure and can manage data deletion processes more directly.
