About the Book

Once the domain of military, diplomatic, and government agencies, computer system and network securitynow affects every organization and individual conducting online banking, e-commerce, or software development. While attackers need only a single point of weakness and have the advantage of surprise, defenders must be prepared everywhere and at all times.

This comprehensive, systematic textbook covers the fundamental theoretical and practical concepts of ICT security. It explains modern threats, attacks, and vulnerabilities alongside proven defensive methods, architectures, and technologies—guiding developers, system administrators, security architects, university students, and business executives on how to protect their computers, networks, source code, and databases.
