In “Know Thy Adversary but first and foremost Know Thyself”， a seasoned cybersecurity executive explores how the timeless strategies of Sun Tzu’s The Art of War offer profound and practical guidance for today’s digital battlefields。 Drawing a straight line from ancient warfare to modern cybersecurity， this book reimagines Sun Tzu’s core teachings through the lens of a practicing Chief Information Security Officer （CISO） navigating today’s high-stakes， high-velocity threat landscape。

At the heart of this exploration is Sun Tzu’s enduring “Know yourself and know your enemy。” The book unpacks how this principle is not just a strategic ideal but a critical operational mandate for CISOs who must continuously assess their organization’s cyber readiness while anticipating the evolving motives and capabilities of adversaries—be they cybercriminals， nation-state actors， or insider threats。
