For computer science, computer engineering, and electrical engineering majors taking a one-semester undergraduate courses on network security.
A practical survey of network security applications and standards, with unmatched support for instructors and students.
In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. Network Security: Applications and Standards, Fifth Edition provides a practical survey of network security applications and standards, with an emphasis on applications that are widely used on the Internet and for corporate networks. An unparalleled support package for instructors and students ensures a successful teaching and learning experience.
Adapted from Cryptography and Network Security, Sixth Edition, this text covers the same topics but with a much more concise treatment of cryptography.
- Comprehensive up-to-date survey of cryptography, authentication, and digital signatures.
Gives the students a solid yet concise overview of the fundamental algorithms and techniques underlying network security.
- Integrated, comprehensive, up-to-date coverage of Internet-based security tools and applications.
This is the only book that provides this coverage.
- Unified, comprehensive treatment of mutual trust topics.
Key management and user authentication are fundamental to the successful use of cryptographic services. This treatment gives the student a systematic and comprehensive understanding of the issues involved.
- Excellent collection of homework problems.
Approximately 150 problems reinforce material in the text and also introduce new concepts and techniques. Problems are included at the end of each chapter.

New to This Edition
- Network access control: A new chapter provides coverage of network access control, including a general overview plus discussions of the Extensible Authentication Protocol and IEEE 802.1X.
- Cloud security: A new section covers the security issues relating to the exciting new area of cloud computing.
- SHA-3: An online chapter covers the new cryptographic hash standard, SHA-3, which was adopted in 2012.
- Mobile device security: Mobile device security has become an essential aspect of enterprise network security. A new section covers this important topic.
- Malicious software: This chapter provides a different focus than that of the fourth edition. Increasingly we see backdoor/rootkit type malware installed by social engineering attacks, rather than more classic virus/worm direct infection. And phishing is even more prominent than ever. These trends are reflected in the coverage.
- Sample syllabus: The text contains more material than can be conveniently covered in one semester. Accordingly, instructors are provided with several sample syllabi that guide the use of the text within limited time (e.g., 16 weeks or 12 weeks). These samples are based on real-world experience by professors with the first edition.
- Learning objectives: Each chapter now begins with a list of learning objectives.
