The insider's guide to IPSec for every network professional—updated for the newest standards, techniques, and applications.

Using IPSec, companies can build VPNs and other Internet-centered applications with confidence that their data will remain secure. IPSec, Second Edition is the most authoritative, comprehensive, accessible, and up-to-date guide to IPSec technology. Two leading authorities in IPSec standardization and implementation cover every facet of IPSec architecture and deployment, review important technical advances since IPSec was first standardized, and present new case studies that show how IPSec can provide end-to-end security in real business environments. Coverage includes:

  • New, in-depth deployment guidance: policy definition, representation, distribution, and management
  • New IPSec enhancements: compression, multicast, key recovery, L2TP support, PKI integration, and more
  • IPSec architecture and components: payloads, headers, Internet Key Exchange, security associations, and more
  • Implementation architecture and techniques, including overlapping and shared security associations, nested and chained tunnels, and more
  • IPSec security in host-to-host, host-to-gateway, and gateway-to-gateway scenarios
  • Establishing secure VPN tunneling
  • A detailed look inside the IPSec kernel

IPSec, Second Edition delivers the techniques and insight you need to protect all your digital assets, wherever they are—on the Internet, your intranet, your extranet, or your VPN. Whether you're a networking or Web professional, software developer, or security specialist, you'll find it indispensable.
