The real-world guide to securing Cisco-based IP
telephony applications, devices, and
networks
Cisco IP telephony leverages
converged networks to dramatically reduce TCO and
improve ROI. However, its critical importance to
business communications and deep integration with
enterprise IP networks make it susceptible to attacks
that legacy telecom systems did not face. Now, there’s a
comprehensive guide to securing the IP telephony
components that ride atop data network
infrastructures–and thereby providing IP telephony
services that are safer, more resilient, more stable,
and more scalable.
Securing Cisco IP
Telephony Networks provides comprehensive,
up-to-date details for securing Cisco IP telephony
equipment, underlying infrastructure, and telephony
applications. Drawing on ten years of experience, senior
network consultant Akhil Behl offers a complete security
framework for use in any Cisco IP telephony environment.
You’ll find best practices and detailed configuration
examples for securing Cisco Unified Communications
Manager (CUCM), Cisco Unity/Unity Connection, Cisco
Unified Presence, Cisco Voice Gateways, Cisco IP
Telephony Endpoints, and many other Cisco IP Telephony
applications. The book showcases easy-to-follow Cisco IP
Telephony applications and network security-centric
examples in every chapter.
This guide is
invaluable to every technical professional and IT
decision-maker concerned with securing Cisco IP
telephony networks, including network engineers,
administrators, architects, managers, security analysts,
IT directors, and consultants.
