If classified information is discovered unprotected, what immediate action should be taken?

The immediate action to secure classified information that is discovered unprotected is to secure it and notify security personnel. This action is essential because unprotected classified information poses a risk of unauthorized disclosure, which can compromise national security, sensitive operations, or individual privacy.

By securing the information, you help prevent any potential access by unauthorized individuals, which may result in harmful consequences. After securing it, informing security personnel is crucial as they are trained to handle such situations and can take appropriate measures to investigate the breach, assess the potential damage, and implement strategies to prevent future occurrences. This protocol aligns with established procedures for handling classified materials and ensures that the situation is addressed promptly and efficiently.

The other choices do not ensure the immediate security of the classified information and could lead to greater risks or complications.
