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. See Chapter Four.
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.
Comprehensive, up-to-date coverage of IP Security.
IPSec is one of the most complex, and one of the most important, new network security standards. This book gives a clear and detailed technical treatment of the topic. Chapter 8 is devoted to IPSec.
Comprehensive, up-to-date coverage of wireless network Security.
The student gains an understanding of the importance of this topic. Chapter 6 is devoted to this topic.
Coverage of both PGP and S/MIME for electronic mail security.
These are the two most important approaches to email security. The book gives the student an understanding of both schemes at a detailed, technical level. Chapter 7 is devoted to PGP and S/MIME.
Unequalled support for projects.
For many instructors, an important component of a course is a project or set of projects that offers students hands-on experience to help reinforce concepts from the text. This book provides unparalleled support in that area. The Instructor's Manual includes guidance on how to assign and structure the projects, and includes a set of suggested projects that covers a broad range of topics from the text. The following types of projects are supported in the Instructor's Projects Manual:
Comprehensive and unified discussion of intruders and viruses.
The threats of intruders (hackers) and viruses are distinct, but there are also similarities. By treating the two in successive chapters and in a unified way, the student gains a greater understanding of both topics. See Chapters 9 & 10.
Treatment of firewalls.
Firewalls are an integral part of any network security capability. See Chapter 11.

What’s New on the Author Web Site http://www.williamstallings.com/NetSec/NetSec4e.html
Wiliiam Stallings' Network Security: Applications and Standards, 4/e is 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, 4/e 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, Fifth Edition, this text covers the same topics but with a much more concise treatment of cryptography. Network Security, 4/e also covers SNMP security, which is not covered in the fifth edition.
Highlights include: expanded coverage of pseudorandom number generation; new coverage of federated identity, HTTPS, Secure Shell (SSH) and wireless network security; completely rewritten and updated coverage of IPsec; and a new chapter on legal and ethical issues.
