In order to access classified information, an individual must be granted a Personnel Security Clearance (PCL) and have a Need-to-know (NTK).

• A. Need-to-know (NTK)
• B. Approved safeguarding capability
• C. Visit Authorization Letter (VAL)
• D. Security clearance level

Answer: (A)

Access to classified information is controlled by two factors: a personnel security clearance and the need-to-know principle. A personnel security clearance shows that an individual has been vetted and is authorized to access sensitive material at a given level. But clearance alone isn’t enough to grant access to every item at that level. The need-to-know rule limits access to information to those whose official duties require it. So, even if someone has a valid clearance, they can access particular classified details only if they have a need to know. The other options don’t function as the standard gatekeeping requirement: safeguarding capability isn’t the criterion for access, a Visit Authorization Letter governs a specific visit rather than ongoing access to information, and the security clearance level is the clearance itself, which is already accounted for and does not by itself grant access without need-to-know.
