Chapter 9: Effective Security Management
by Ken Camp

The convergence of voice, video, and data networks has been evolving and gaining momentum for the past several years. Many organizations have undertaken VoIP implementation to converge networks for cost reduction. Others work to achieve the competitive advantage of integrated services. Whatever the reason for network service integration, you cannot overlook the security risks that arise as technologies converge. VoIP implementers often focus on issues of voice quality, and interoperability. These are truly important factors in the delivery of voice services. In many ways inside the converged service network, voice security needs to be treated as data security. And data security needs to be treated as voice security. Both technologies bring issues and management techniques that benefit the other. Chapter 9 will highlight security management issues facing enterprise deployments today and identify common industry best practices for creating an effective and comprehensive security plan that balances securing the network against the VoIP requirements for availability, reliability, and performance.

Chapter 4: Virtualization Management Challenges
by Anil Desai

Although virtualization technology can provide many significant advantages to IT environments, the use of virtual machines is not without potential drawbacks. Many IT organizations have come to the realization that initial purchase costs of hardware and software represent only a relatively small portion of overall expenditures. Additional factors that contribute to the bottom line include expenses related to administration, maintenance, and monitoring. The focus in Chapter 4 is on highlighting the types of issues that environments are likely to face as they manage infrastructures that contain a mix of physical and virtual computing technologies. The focus is on identifying the problems and how they can have a huge effect on overall IT environments.

Chapter 4: Design and Pre-Deployment
by Jim Cavanagh

True or false: Implementing VoIP is as simple as plugging your telephone into the Internet and getting free voice. At this point, we’ve established that this statement is false. Chapter 3 described the first phase in the life cycle of any successful VoIP or IPT project-planning and assessment. The information that you gathered and the steps that you took in this phase set the stage for the next step: design and pre-deployment testing, which is what we explore in Chapter 4.
