Data from a system of sensors located outside of a network is received by the open ports on a server. Which of the following is the BEST way to ensure the integrity of the data being collected from the sensor system?
A.
Implement network address translation on the sensor system
B.
Route the traffic from the sensor system through a proxy server.
C.
Transmit the sensor data via a virtual private network (VPN) to the server
D.
Hash the data that is transmitted from the sensor system
The BEST way to ensure the integrity of the data being collected from the sensor system is option D: Hash the data that is transmitted from the sensor system.
Here's why:
D. Hashing the data that is transmitted from the sensor system is a fundamental technique for ensuring data integrity. By hashing the data at the source and verifying the hash on the receiving end, you can detect any changes or tampering with the data during transit. If the hash values match, you can be reasonably certain that the data hasn't been altered in transit.
In summary, while options B and C can enhance security, they don't directly ensure data integrity. Option A is more about network address management. Option D, hashing the data, is the most appropriate choice to verify data integrity.
D. Hash the data that is transmitted from the sensor system
