Which of the following can be considered a legitimate need-to-know?

The answer is based on the concept of "need-to-know," which is an essential principle in information security and classified materials management. A legitimate need-to-know is defined by whether the individual requires access to specific information in order to perform their duties effectively and responsibly.

Being currently involved in related work directly establishes a valid necessity for access to the information in question. When someone is actively engaged in tasks that relate to classified projects, they require relevant information to make informed decisions, execute their responsibilities, and ensure that their work aligns with the overarching project goals and security protocols. This connection between current involvement and the need for specific information underpins the legitimacy of the need-to-know principle.

In contrast, general interest in classified projects is insufficient to grant access, as it does not arise from a necessity tied to job responsibilities. Similarly, past experience, while valuable, does not establish a current need; individuals may no longer require that information based on their current roles. Lastly, assuming responsibility for information security does imply a level of authority but does not automatically confer access to classified information unless accompanied by a direct need related to specific work tasks.
