In today's hyperconnected and digitized world, cybersecurity has become an important strategic imperative owing to the sophistication of cybercrime. Digital businesses require complex and distributed interactions among people, applications and data - on premise, off-premise, on mobile devices and in the cloud. The result is an increase in the attack surfaces that are hard to protect and defend. As the perimeter continues to diminish, visibility into the environment gets tougher. Operational Technology (OT) and the Internet of Things (IoT) massively expand the scope of security strategy and operations. When a massively distributed fleet of autonomous devices that can make decisions is combined, directly affecting the physical state of people and things, there is a considerable risk to manage. This issue is not limited to the chief information security officer (CISO) but needs the involvement and sponsorship of the leadership and the board.
