A security engineer is assessing a new IoT product.
The product interfaces with the ODBII port of a vehicle and uses a Bluetooth connection to relay data to an onboard data logger located in the vehicle.
The data logger can only transfer data over a custom USB cable.
The engineer suspects a replay attack is possible against the cryptographic implementation used to secure messages between segments of the system.
Which of the following tools should the engineer use to confirm the analysis?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
In this scenario, the security engineer suspects that a replay attack is possible against the cryptographic implementation used to secure messages between different segments of the system. The engineer needs to confirm the analysis by using the appropriate tool.
Option A - Vulnerability Scanner: A vulnerability scanner is a tool used to identify vulnerabilities in a system or network. However, in this scenario, a vulnerability scanner would not be the most appropriate tool to confirm the analysis of a replay attack.
Option B - Wireless Protocol Analyzer: A wireless protocol analyzer is a tool used to capture and analyze network traffic over wireless networks. In this scenario, the product interfaces with the ODBII port of a vehicle and uses a Bluetooth connection to relay data to an onboard data logger located in the vehicle. Therefore, a wireless protocol analyzer could be used to capture and analyze the Bluetooth traffic to determine if there are any replay attacks happening.
Option C - Log Analysis and Reduction Tools: Log analysis and reduction tools are used to analyze log data and identify patterns and anomalies that may indicate suspicious activity. In this scenario, this tool would not be the most appropriate to confirm the analysis of a replay attack.
Option D - Network-based Fuzzer: A network-based fuzzer is a tool used to identify vulnerabilities in network-based applications by sending malformed or unexpected inputs. In this scenario, a network-based fuzzer would not be the most appropriate tool to confirm the analysis of a replay attack.
Therefore, the best tool to confirm the analysis of a replay attack in this scenario would be a wireless protocol analyzer (Option B), as it could be used to capture and analyze the Bluetooth traffic to determine if there are any replay attacks happening.
