This book is the outcome of a review of literature on the possible concerns and issues Small and Medium-Sized Enterprises (SMEs) would face when adopting the fourth industrial revolution (4IR) technologies. From a review of the current and past literature, this book disseminates insightful ideas and developments in the field of information and cybersecurity. It is intended that these ideas will shape how SMEs now and in the immediate future address information and cyber security risks. This book is also of particular interest to information security administrators managing SME information security, who may gather additional insights on the emergent information security threats facing SMEs that are discussed. A key consideration for this book is the innovative ways that SMEs have adopted 4IR technologies but, in doing so, have attracted unknown information and cyber security risks.
