Book excerpt: In today's digital age, cyber threats have become an ever-increasing risk to businesses, governments, and individuals worldwide. The deep integration of technology into every facet of modern life has given rise to a complex and interconnected web of vulnerabilities. As a result, traditional, sector-specific approaches to cybersecurity have proven insufficient in the face of these sophisticated and relentless adversaries. The need for a transformative solution that transcends organizational silos and fosters cross-sector collaboration, information sharing, and intelligence-driven defense strategies is now more critical than ever. Evolution of Cross-Sector Cyber Intelligent Markets explores the changes occurring within the field of intelligent markets, noting a significant paradigm shift that redefines cybersecurity. Through engaging narratives, real-world examples, and in-depth analysis, the book illuminates the key principles and objectives driving this evolution, shedding light on innovative solutions and collaborative efforts aimed at securing our digital future.
