Cyber-informed engineering is a design approach that builds cybersecurity into physical systems from the start. Instead of treating security as an add-on, engineers ask how a cyber compromise could affect safety, reliability, and operations. This matters most in critical infrastructure and industrial control systems, where a digital failure can become a physical hazard, service outage, or unsafe process state. A central idea is consequence analysis: identify the worst credible outcomes before choosing controls.
In practice, cyber-informed engineering changes how systems are built and defended. Designers may add isolation, redundancy, manual fallback modes, fail-safe behavior, or independent safeguards so a compromised controller cannot cause maximum damage. Defenders use it to reduce the blast radius of attacks such as set-point changes, controller manipulation, or disruption of control communications. The goal is not perfect prevention, which is unrealistic, but bounded consequence: even if attackers get in, the system should still fail safely.
