Recent years have seen a proliferation of cybersecurity guidance in the form of government regulations and standards with which organizations must comply. As society becomes more heavily dependent on cyberspace, increasing levels of security measures will need to be established and maintained to protect the confidentiality, integrity, and availability of information; the privacy of consumers; and the continuity of economic activity. Compliance is a measure of the extent to which a current state is in conformance with a desired state. The desired state is commonly operationalized through specific business objectives, professional standards, and regulations. Assurance services provide a means of evaluating the level of compliance with various cybersecurity requirements. The proposed book will summarize current cybersecurity guidance and provide a compendium of innovative and state-of-the-art compliance and assurance practices and tools that can function both as a reference and pedagogical source for practitioners and educators. This publication will provide a synopsis of current cybersecurity guidance that organizations should consider in establishing and updating their cybersecurity systems. Assurance services will also be addressed so that management and their auditors can regularly evaluate their extent of compliance. This book should be published because its theme will provide company management, practitioners, and academics with a good summary of current guidance and how to conduct assurance of appropriate compliance.
