Global Agencies Release New Guidance to Secure Industrial Networks

A multinational guidance led by NCSC-UK and co-released by CISA, FBI, and partners outlines principles for building secure connectivity in operational technology (OT) environments, urging security-by-design to reduce exposure to both sophisticated and opportunistic adversaries. The document addresses growing OT-IT interconnections that improve efficiency but expand attack surfaces, with risks including physical harm and service disruption. It underscores the importance of adversarial emulation to validate defenses against tactics used by groups such as China’s Salt Typhoon and Russia’s CARR.
