VoIP security issues are becoming increasingly serious because voice networks and
services cannot be protected from recent intelligent attacks and fraud by traditional
systems such as firewalls and NAT alone.
After analyzing threats and recent patterns of attacks and fraud, consideration
needs to be given to the redesign of secure VoIP architectures with advanced protocols
and intelligent products, such as Session Border Controller (SBC). Another type of
security issue is how to implement lawful interception within complicated service
architectures according to government requirements.
The book "Voice over IP
Security," by Patrick Park, focuses on the analysis of current and future
threats, the evaluation of security products, the methodologies of protection, and best
practices for architecture design and service deployment. This book not only covers
technology concepts and issues, but also provides detailed design solutions featuring
current products and protocols so that you can deploy a secure VoIP service in the real
world with confidence. This excerpt is the book's entire first chapter entitled,
"Working with VoIP." In this chapter, you learn about the benefits and disadvantages of
using VoIP, its vulnerabilities and components, and this chapter also dispels some
myths. The content in this chapter refers to recommendations from the National
Institute of Standards and Technology.
