Network Security Essentials Applications and Standards (5th Edition)

As we enter the age of universal electronic connectivity in which viruses, hackers, electronic eavesdropping, and electronic fraud can threaten the prosperity and productivity of corporations and individuals, security is increasingly important. Fortunately, the discipline of network security has matured, leading to the development of practical, available applications to enforce network security. This book provides an integrated, comprehensive, up-to-date coverage of internet-based security tools and applications vital to any treatment of data communications or networking.

Best-selling author and four-time winner of the TEXTY Award for the best computer science and engineering text, William Stallings provides a practical survey of both the principles and practice of network security.

Well organized to provide the optimal sequence for classroom instruction and self-study, this text includes these key features. Covers important network security tools and applications, including Kerberos, X.509v3, PGP, S/MIME, IP security, SSL/TLS, and SET. Chapters on Web security and network management security (SNMPv3). Looks at system-level security issues, including the threat of and countermeasures for intruders and viruses, and the use of firewalls and trusted systems. On-line transparency masters, an Internet mailing list, and links to relevant Web sites are available at
