What are the main differences between IT and OT security priorities in Industry 4.0?

All answers to this question.

In the OT world, we follow the "AIC" triad: Availability, Integrity, and then Confidentiality. If a hacker steals a recipe (Confidentiality), it’s bad; but if they stop a cooling pump (Availability), the plant could literally explode. This is why we are hesitant to run automated scans that might crash a sensitive controller. In 2024, the balance is found in passive monitoring tools that listen to network traffic without sending "pings" that could overwhelm older equipment. Always prioritize the physical safety of the operators over the encryption of the data packets.

Does your team currently involve the safety engineers in your security audits, or is the IT department still running the show independently?

• Robert, we are trying to create a joint task force. The safety engineers are worried that multi-factor authentication might slow down emergency responses on the HMI screens.

It's all about the "Real-time" factor. IT can wait for a reboot; OT cannot. You need to implement security measures that have zero latency.

• Jennifer is right. In a high-speed assembly line, even a 50ms delay caused by a firewall inspection can lead to mechanical synchronization issues.
