If you have the responsibility to enforce security policies for your ATM networks, implementing ATM security devices (both hardware and software), or simply need to better understand the mechanisms defined in the ATM Forum Security Specification 1.1, this book should be useful reading. Specifically targeted at ATM network security, including cryptographic and architectural techniques, it provides the reader with a solid understanding of the current and future state of ATM security. From an introduction to network security and fundamentals, to implementing and using ATM security, security association establishment protocols, initial authentication, data origin authentication/integrity, encryption, access control, and PNNI routing, this book provides practical need-to-know information for network architects, ATM security implementers and researchers who wish to gain a thorough understanding of the current and future state of ATM security standards and mechanisms.
