Stiennon on Security is a collection of over 100 essays written by Richard Stiennon between 2010 and 2020. They origianlly appeared in what are now heavily encumbered online media that are so plastered with ads, pop-ups, and videos, that it makes reading difficult. Reading these in book form gives you an opportunity to review the last ten years of developments in the cybersecurity world without distraction. Stiennon has covered the cybersecurity industry from attacks to cyber warfare, to cyber policy, for twenty years. In this first book in a series makes much of his thoughts available in one place. It is a valuable collection for the student of cybersecurity history as well as those who want to reflect on the past.
