Concepts and Practices for Cyber Security

This book is borne out of the experiential learning of its two authors during their long careers in public service. While the objective is to address the compelling need for cyber security awareness in the age of information systems, the focus is on both theory and practice. In an evolving domain such as the cyber security, an understanding of its fundamentals is vital. Keeping this in view, the book starts with the basic concepts behind the development and operation of information systems. As is necessary for a book on security, it highlights threats to information systems next. Guidelines for formulation of cyber security policies and the means for their implementation and operation constitute the middle core of the book. Incorporating cyber security during the many stages of a system development cycle is given due coverage next, followed by a discussion on applicable standards. The penultimate chapter gives an overview of the emerging domain of quantum information technology and its impact on cyber security. The treatment of the subject is at a level accessible to the middle-level managers in public and private organisations. At the same time, experts in the domain too would find something to reflect upon and to evolve new solutions to the persisting problems of cyber security.
