Industrial systems face imminent post-quantum threats due to long lifecycles, often extending 10–30 years, making early planning essential for cryptographic agility. Experts recommend inventorying current cryptographic protocols, engaging vendors on readiness, and gradually upgrading based on business risk and system criticality.
Organizations must focus on modular cryptographic libraries, externalized key management, and updatable trust anchors to ensure systems can adapt without major redesign or operational disruption. This approach is crucial given the limited maintenance windows and operational constraints in OT environments. Early inventory and phased upgrades are vital for mitigating future risks while addressing current security needs.
