A company is upgrading its building's physical security from traditional metal keys to a modern key fob access control system. Which of the following is the most significant security advantage provided by the key fob system?
It provides a detailed electronic audit trail of all access events.
The system's locks are completely immune to physical tampering and brute-force attacks.
Key fobs are universally compatible with any access control reader, regardless of the manufacturer.
Lost or stolen fobs can be deactivated instantly without needing to change the locks.
The correct answer is that key fob systems provide a detailed electronic audit trail. A primary security advantage of electronic access control systems, such as those using key fobs, is their ability to log every access attempt. This creates an audit trail that shows which user accessed a specific location and at what time, which is invaluable for security monitoring and incident investigation. While deactivating a lost fob is a major benefit, the comprehensive logging capability is the most significant security enhancement over traditional keys, which provide no access tracking. Key fobs can be lost, and while electronic locks are not vulnerable to traditional lock picking, they are not completely immune to all forms of tampering.
