The most common and efficient manner of securing operating systems is through the use of baselines. A baseline is a standardized and understood set of base configurations and settings. When a new system is built or a new virtual machine is established, baselines will be applied to a new image to ensure the base configuration meets organizational policy and regulatory requirements.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

SOC Type 1 reports are considered "restricted use" reports. They are intended for management and stakeholders of an organization, clients of the service organization, and auditors of the organization. They are not intended for release beyond those audiences.

Sandboxing involves segregating and isolating information or processes from others within the same system or application, typically for security concerns. This is generally used for data isolation (for example, keeping different communities and populations of users isolated from other similar data).

Explanation:
While hard drives may be useful in the kit (for instance, if they store BC/DR data such as inventory lists, baselines, and patches), they are not necessarily required. All the other items should be included.
