“Essentials of Cyber Security” shares best practices for policy and governance, operations and worst-case scenarios. It discusses the significance of safeguarding not only the network, but also the systems, applications, and data contained inside it. It also discusses how to incorporate IT security specialists earlier in the life cycle of new projects, as well as the need of robust policy and risk management. This book also provides insight into security practices for three areas that are rapidly becoming more important in the current threat landscape: applications, the cloud and mobility.
