A financial institution uses video cameras to record activities at all teller windows where high-value transactions occur. Which of the following BEST explains the primary security benefit of this practice?
It acts as a deterrent by making the transaction process more complex for would-be criminals.
It guarantees the integrity of the transaction data stored on the company's servers.
It provides visual evidence that prevents individuals from denying their involvement in a transaction.
It keeps the financial details of the transaction confidential from unauthorized individuals.
Video recordings provide a visual account of events that can serve as undeniable proof that a particular action or transaction took place, including the identities of the people involved. This mechanism is a form of non-repudiation, as it prevents a party from falsely denying their participation. While video might deter fraudulent activity, its primary security function is to create an indisputable record of events. Other security principles like confidentiality and integrity are typically handled by different controls.
