Which of the following may be prevented by adding locks and video cameras to the refuse collection location?

Eavesdropping involves secretly listening to private conversations or communications, which physical security at a refuse site does not prevent.

Social engineering involves manipulating people into divulging confidential information, which is a human-centric attack not directly addressed by physical security for trash.

Tailgating involves an unauthorized person following an authorized person into a secured area, which is related to entry points into buildings, not typically refuse collection points in this context.

Dumpster diving involves sifting through trash to find sensitive information or discarded assets, and securing the refuse collection area with locks and surveillance cameras directly deters this activity by controlling access and monitoring the area. This prevents unauthorized retrieval of potentially confidential documents or data storage devices.
