Which is a key control for a secure online banking system?

• A. Strong authentication
• B. Public sharing of credentials
• C. Unencrypted traffic
• D. Lack of monitoring

Answer: (A)

Strong authentication is essential for a secure online banking system because it verifies the user’s identity with more than just a simple password, often combining something the user knows, has, or is. This layered approach makes it much harder for attackers to gain unauthorized access, protecting sensitive accounts and transactions from fraud and data theft. Public sharing of credentials completely defeats this protection since secrets must remain with the legitimate user; unencrypted traffic allows interception of login details and other sensitive data, compromising confidentiality and integrity; and lack of monitoring means suspicious activity can go unnoticed and unaddressed. Together, strong authentication stands out as a fundamental control for keeping online banking secure.
