A worker scanned her "eyes only" secret notes she prepared using a public scanner while no one is watching. His$/$her intention is to store the soft copy of the notes in a secure computer $($Top Secret$/$SCI$)$ system and destroy the originals.

Question $8$ options:

Since no one is watching this is ok

Since her office has physical security, this is not a concern.

Since her office is located on the fifth floor of the building, it is unlikely that signals can be captured from outside.

This is a serious security violation of the policy but is partially due to human factors and an incorrect mental model. Many scanners store data in their internal hard drive$/$storage and modern scanners may also be connected to the network. Many users are not aware of the vulnerabilities of such scanners.
