What does double-key encryption in Microsoft 365 require?

• A. Two different passwords for each user.
• B. Both Microsoft's key and the organization's key to access data.
• C. A single encryption key for all data.
• D. Third-party access for encryption.

Answer: (B)

Double-key encryption is a robust security feature in Microsoft 365 that enhances data protection by requiring access to both Microsoft's encryption key and the organization's own encryption key. This dual-key mechanism ensures that even if one key is compromised, the data remains secure because the other key is still required for decryption. The rationale behind this approach is to give organizations more control over their encrypted data. By managing their own key alongside Microsoft’s key, organizations can implement more stringent security policies, enhance compliance with regulatory requirements, and bolster their data's privacy. This method specifically mitigates risks associated with sole reliance on a single key, providing an additional layer of security, especially in scenarios involving sensitive or regulated information. It is particularly valuable for organizations that are concerned about data access during legal investigations or regulatory audits, as it allows them to maintain control over their own data without entirely depending on the service provider.
