The nature of cybersecurity has changed. Since manufacturing companies have begun to link operational technologies (OT) from their manufacturing chain to their information systems (IT), any cyber-attack can not only damage computer data, but also physical devices. Any machine thus connected can be slowed down, stopped or destroyed remotely. It is no longer our computer or our information that is at stake. It is our physical goods and, ultimately, our lives.Are Canadian businesses and critical infrastructures protected? To answer this question, the Canadian Advanced Technology Alliance (CATA) surveyed more than 200 companies throughout the country. It then organized one-to-one interviews with 28 cybersecurity officers.
