It's only a matter of time before you are involved with a cybersecurity incident. That's not fear-mongering, that's the truth. Businesses and organisations that respect this will be at the forefront of planning to prevent it, but even the most prepared are fallible and adversaries are evolving on a day-to-day basis.
