Compressed air is pressurized air used in industrial systems to move, shape, or stabilize material flow. In manufacturing, it can drive actuators, feed extrusion heads, or help control the form of a part. Because pressure directly affects motion and output, it is often treated as a process input rather than just a utility.
In cyber security, compressed air matters in operational technology and industrial control systems. If an attacker changes compressor settings, valve commands, or pressure setpoints through a PLC or HMI, they can distort product quality, interrupt production, or create unsafe conditions. Defenders monitor pressure, flow, and controller state for anomalies, limit remote access to control networks, and verify that setpoints match expected ranges. In short, compressed air is a physical signal that can be protected, manipulated, or abused like any other part of an automated process.
