HOW DECADES OF DISCONNECTED MODERNIZATION CREATED OT SECURITY DEBT MANUFACTURERS CAN'T ESCAPE

Summary from the TLDR IT newsletter

Decades of disconnected modernization have created a severe OT security debt crisis for manufacturers, as new technologies were built on legacy systems without proper network segmentation or security architecture. Flat networks, default administrator accounts, and permanent remote access links have vastly expanded the attack surface, turning single footholds into enterprise-wide risks. Addressing this exposure requires asset visibility, realistic exposure management, and tailored controls for brownfield environments rather than complete system replacements.
