Which of the following is a way bank policies ensure security for customers?

The establishment of protocols for transactions and fraud detection is crucial for ensuring customer security in a banking environment. These protocols are designed to identify suspicious activities, implement measures to prevent unauthorized access, and monitor transactions to safeguard against fraud. By having clearly defined procedures, banks can respond quickly to potential security threats, thus protecting customer accounts and personal information.

Protocols for fraud detection often include monitoring unusual transaction patterns, implementing two-factor authentication for account access, and regularly training employees on recognizing and reporting suspicious behavior. Such measures build trust and confidence among customers, knowing that their financial security is a top priority for the bank.

While the other options might contribute to the overall operations of a bank, they do not directly address the critical area of customer security in the same way that established protocols provide.
