This book is short and purposefully presented as a quick read for those who need an overview on the topic of cyber security. Keats speaks about the threats users and organisations face, presents examples of typical threats and suggests ideas for preventing threats. His style is easy to read for the business and general reader and is not aimed at the IT specialist. It provides both a useful background and information to better position many people to know what questions to ask and how to understand the threats without being an IT expert.
