Synopsis
The Barnes & Noble Review
IPSec VPNs: they offer the potential of powerful cost savings compared with yesterday's long-distance and leased line charges, even if they're still far tougher to install and manage than they should be. If you're deploying or considering an IPSec-based VPN, and you really want to understand the technology and the industry, check out IPSec: Securing VPNs. It's one of the first books from RSA -- folks who go back to the very beginnings with public-key cryptography -- and the pedigree shows.
Carlton Lewis starts by making sure you're comfortable with the technologies IPSec is built on, introducing public-key cryptosystems, hash functions and message authentication codes, the key components of a public-key infrastructure, alternatives such as the PGP trust model, and the role of LDAP-based directories in IPSec VPNs.
Next, Lewis introduces the IPSec security architecture itself, including security associations, policies, and databases. He shows how Authentication Headers guarantee the security of packets, how the Encapsulating Security Payload ensures their confidentiality; and how Internet Key Exchange makes it possible to negotiate keys remotely and secretly.
From technology to products to the future of IPSec itself, IPSec: Securing VPNs is the authoritative, systematic guide technical professionals have been looking for. (Bill Camarda)
