Book Review: Securing Cisco IP Telephony Networks - By Akhil Behl Double CCIE (Voice & Security) #19564

 Reviewer: Arani Mukherjee

The days of staring at a mess of wires under the desk coming out of a PSTN Master Socket are truly over. The advent of VoIP has broken the stranglehold of a telephone cable and the network has finally taken over. I would not say that IP Telephony has revolutionised the telephony sector. That momentous transition happened years ago. We currently are going through a phase where it is common to have IP Telephony integrated into any enterprise and network administrators are actively implementing security measures and policies to it. Network security is of paramount importance and IP Telephony is not to be left behind. The fact is that Cisco, the market leader in network technology, also happens to be leading the IP Telephony field. Hence it has rightly decided that establishing robust security architecture is core to Cisco IP Telephony.

The latest Cisco title addresses the aforementioned issue promptly and efficiently. Whenever a technology becomes efficient, scalable and portable and is seen as an improvement on the incumbent technology, it is deemed indispensable. From that moment it also becomes a point of failure that can cripple a business because it has now inherited security vulnerabilities and threats. The same can be said about Cisco IP Telephony. What this book aims to achieve is, and I quote, “to explain an End-to-End IP Telephony Security approach and architecture…” And I assure you, this title does plenty of justice to that aim. So let’s dig deeper into the way this book deals with the issues and how it tackles security policies, principles and their respective implementations.
