Machine-to-machine security focuses on securing the communication between devices, such as programmable logic controllers and engineering workstations, without human intervention. Instead of relying on static application programming interface (API) keys that can be stolen, modern security frameworks use short-lived tokens and cryptographically bind identities to specific hardware. This ensures that only authorised machines can talk to one another, preventing rogue devices from injecting malicious commands. Our blueprint for industrial security details these hardware-bound protections.
