Which of the following is NOT a principle of protecting sensitive accounts and encryption keys?

The principle of protecting sensitive accounts and encryption keys emphasizes the importance of keeping critical security elements separate from the data they are meant to protect. Storing the Operator Key alongside sensitive data undermines this principle by creating a situation where a single security breach could expose both the sensitive data and the key needed to access it.

In contrast, using physical safes for key storage ensures that keys are securely stored and only accessible to authorized personnel, thus providing a strong layer of physical security. Utilizing the Microsoft Windows Password Reset Disk utility is a mechanism to provide recovery options for lost passwords, which can also relate to secure account management practices. Assigning keys to different organizational entities promotes segregation of duties and minimizes the risk of a single point of failure. In all these cases, key management is emphasized as a critical security practice, whereas the option that indicates storing the Operator Key with the sensitive data directly violates fundamental security principles.
