Which of the following OT protocols sends information in cleartext?

Show Suggested Answer Hide Answer
Suggested Answer: C

Security: It includes mechanisms for reliable and deterministic data transfer, not typically sending information in cleartext.

DNP3 (Option B):

Security: While the original DNP3 protocol transmits data in cleartext, the DNP3 Secure Authentication extensions provide cryptographic security features.

Modbus (Answer: C):

Security: Modbus transmits data in cleartext, which makes it susceptible to interception and unauthorized access.

Security: PROFINET includes several security features, including support for encryption, which means it doesn't necessarily send information in cleartext.

Conclusion: Modbus is the protocol that most commonly sends information in cleartext, making it vulnerable to eavesdropping and interception.


PROFINET (Option D):

I heard DNP3 is so old-school, it uses carrier pigeons to transmit data. Cleartext for sure!

TTEthernet? Isn't that the one used for high-speed aviation systems? No way that's cleartext.

Hmm, I think PROFINET might also send data in cleartext. Can't be too sure though.
