Description
Information is one of the most valuable assets in the hyperconnected digital world. While digital technologies create immense opportunities, they also introduce significant risks. Cyber threats have evolved in sophistication, speed, and scale, making the protection of information systems more critical than ever. Information security is a multidisciplinary field that encompasses the principles, technologies, and practices designed to protect information assets from theft, corruption, unauthorized access, and disruption.
This book introduces the fundamental concepts of information security and explores key areas such as governance, risk management, and compliance that support effective security programs. Readers will learn how cryptography protects sensitive information, how identity and access management regulates user access, and how networks and systems are secured. The book also covers endpoint, application, and cloud security, security operations, and emerging technologies such as AI and quantum computing that are reshaping the cybersecurity landscape.
By the end of this book, readers will have a strong understanding of information security fundamentals and their application in real-world environments. They will be equipped to evaluate security risks, apply protection strategies, and build a solid foundation for further study or professional practice in cybersecurity.
