In a recent audit of a secure facility, it was noted that the employee access system employs badges that are not programmed to confirm the identity of the badge reader before transmitting data. Which specific vulnerability are these badges most at risk of?
The badges in question are at risk of Radio-Frequency Identification (RFID) cloning. The lack of a mutual authentication process in the badge system permits an attacker to easily capture the badge's signal and create a duplicate without being verified by the reader. This process leads to unauthorized individuals potentially gaining access to secured facilities. Mutual authentication is a security feature where a badge and its reader verify each other before any data is transmitted. Options such as 'Email compromise' and 'Social engineering tactics' are not directly related to the scenario described where radio-frequency signals could be exploited. 'Encryption breaking' is also incorrect as it doesn't directly pertain to the cloning of an RFID signal, which is an issue distinct from cryptographic weaknesses.
