What category does the scenario of transmitting personal employee information remotely (including addresses and phone numbers) BEST fit?

The scenario of transmitting personal employee information, such as addresses and phone numbers, is best classified as "Private" information. This category pertains specifically to data that pertains to individuals and their personal lives, which is sensitive and should be protected to maintain individuals' privacy.

Private information includes any data that can be used to identify a person and is often regulated by laws and standards such as GDPR or HIPAA. The transmission of such information typically requires a higher level of security due to its personal nature. Organizations must ensure that appropriate measures are in place to protect this data during transmission and storage to avoid breaches and misuse.

In contrast, while "Confidential" could seem like a strong contender, it usually applies to information that requires protection within an organization, but not to the same personal extent as private information. "Internal" information generally refers to data meant solely for organizational use and does not address the personal aspect. "Public" represents information that is accessible to anyone, which does not apply here since personal employee data is distinctively sensitive and not for public knowledge.
