Which indicator tracks and logs failed login events to detect unauthorized access attempts?

• A. Iris Recognition
• B. Gait Recognition
• C. Vein Matching
• D. Failed Login Attempts

Answer: (D)

Tracking authentication activity is about auditing access attempts to spot potential unauthorized access. The indicator that tracks and logs failed login events directly records unsuccessful attempts, such as incorrect passwords or repeated tries, which helps identify brute-force or credential-stuffing patterns and supports alerts, rate limiting, and account protections. Biometric methods like iris recognition, gait recognition, and vein matching are used to verify identity during login, but they don’t inherently provide a log of failed login events or serve as a monitoring signal for unauthorized access attempts. Therefore, the indicator that logs failed login events is the one that best fits this purpose.
