With multitenancy, where different cloud customers all share the same physical systems and networks, data classification becomes even more important to ensure that the appropriate security controls are applied immediately to prevent any potential leakage or exposure to other customers. Portability refers to the ability to move easily from one cloud provider to another. Interoperability refers to the ability to reuse components and services for different uses. Reversibility refers to the ability of the cloud customer to quickly and completely remove all data and services from a cloud provider and to verify the removal.

Security should be included in discussions from the very first phase when defining the scope. Adding security later is likely to incur additional costs in time and money, or will result in an incomplete or inadequate plan.

Explanation:
Firewalls work at the network level and control traffic based on the source, destination, protocol, and ports.
Whether or not the traffic is encrypted is not a factor with firewalls and their decisions about routing traffic.
Firewalls work primarily with IP addresses, ports, and protocols.

Object storage uses a flat structure with key values to store and access objects.

The SOC Type 2 audits include five principles: security, privacy, processing integrity, availability, and confidentiality.
