Explanation
Background checks are controls for attenuating potential threats from internal actors; external threats aren't likely to submit to background checks.

Explanation
KRI stands for key risk indicator. KRIs are the red flags if you will in the world of risk management. When these change, they indicate something is amiss and should be looked at quickly to determine if the change is minor or indicative of something important.

Cryptographic erasure involves having the data encrypted, typically as a matter of standard operations, and then rendering the data useless and unreadable by destroying the encryption keys for it. It represents a very cheap and immediate way to destroy data, and it works in all environments. With a cloud environment and multitenancy, media destruction or the physical destruction of storage devices, including shredding, would not be possible. Depending on the environment, overwriting may or may not be possible, but cryptographic erasure is the best answer because it is always an available option and is very quick to implement.

Explanation
With a Type 1 hypervisor, the hypervisor software runs directly on top of the bare-metal system, without any intermediary layer or hosting system. None of these statements describes a Type 1 hypervisor.

Explanation
Portability is the ability for a cloud customer to easily move their systems, services, and applications among different cloud providers. By avoiding reliance on proprietary APIs and other vendor-specific cloud features, an organization can maintain flexibility to move among the various cloud providers with greater ease.
Reversibility refers to the ability for a cloud customer to quickly and easy remove all their services and data from a cloud provider. Interoperability is the ability to reuse services and components for other applications and uses. Scalability refers to the ability of a cloud environment to add or remove resources to meet current demands.
