Imagine quantifying and visualizing your organization's cyber resilience as precisely as a stock market index. This book introduces that reality through the innovative Cyber Resilience Index, a unified metric that helps master threat-informed defense, transform cybersecurity strategy, and achieve efficient and effective threat management and communication.

Through an engaging dialogue between a seasoned CISO Sophia and an innovative security leader Alex, you are taken on a journey from traditional, reactive defense to a proactive, resilience-focused strategy. The book masterfully blends technical depth with strategic insights, explaining the paradigm shift from asset-driven to threat-intelligence-driven security. You will learn how and why compliance is very important, but not enough to be truly cyber resilient; how to construct and leverage interoperable cyber value chains; how to go beyond continuous threat exposure management programs and truly master the threat-informed defense concepts; how to articulate value, and manage your cyber defense through a unified metric (much like traders use stock market charts to make successful trading decisions); and, lastly, what the evolution of cybersecurity leadership looks like ahead.

Whether you're a cybersecurity professional, a subject matter expert (SME), a business leader, a security leader, or an expert in the field looking for battle-tested ways to sharpen or develop your leadership skills, this book provides a new lens through which to view the future of cybersecurity and leadership. Are you ready to reshape the chessboard of cyber defense?
