Description: Opening with a tutorial and survey on network security technology, Stallings provides a sound mathematical foundation for developing the algorithms and results that are the cornerstone of network security. Each basic building block of network security is covered, including conventional and public-key cryptography, authentication, and digital signatures, as are methods for countering hackers and other intruders and viruses. The balance of the book is devoted to an insightful and thorough discussion of all the latest important network security applications, including PGP, PEM, Kerberos, and SNMPv2 security. Now in its Second Edition, the book has been completely updated, reflecting the latest developments in the field.
