Principles of Network Security

Principles of Network Security offers a comprehensive, approachable, and up-to-date foundation for teaching network security to students in high school, trade school, or college-level courses. This textbook introduces core concepts in network security, cryptography, secure architecture, threat analysis, and monitoring while addressing modern challenges like IoT, cloud security, AI, and Zero Trust frameworks. Each chapter combines foundational theory with real-world examples and current best practices.

The book emphasizes practical knowledge across layered topics, from the OSI and TCP/IP models and data communication protocols to firewall configuration, VPN deployments, wireless network protections, and access control models. It includes coverage of leading standards and frameworks from NIST, CIS, and ISO. Rich pedagogical features - such as learning objectives, review questions, hands-on exercises, and short projects - help reinforce key skills and prepare students for further study or entry into cybersecurity roles. 

Whether used in a semester-long survey or as a base for certification pathways, this textbook equips students with the knowledge they need to navigate the complexities of modern network security.
