Who this book is for

This book is meant for anyone looking to embark on the journey of setting up a cyber defense team (AKA a blue team) for their organization. It is business agnostic, and hence professionals from all fields will find it equally useful. The primary goal of the book is to explain all the aspects of setting up such a capability and to ensure there is comprehensive coverage and no blind spots. This involves understanding not just the organization’s needs and risk appetite, but also looking into the applicable laws and regulations, before designing the relevant controls. This will ensure the organization gets the most value from its investments, and that the designed defense capabilities are fit for purpose.
The book is designed to keep senior executives in mind. Hence, Chief Information Security Officers (CISO), Chief Information Officers (CIOs), board members, and other C-level executives will benefit from the strategies and concepts introduced in this book. However, even junior professionals in the information security domain will find value in collecting their thoughts to design a plan that could be presented to the senior executives at their respective organizations.
