Inside the book

When you graze through the book, you instantly realize the stuff is very technical and therefore not proposed at an inexperienced audience. You should look for elsewhere if you are anticipating introductory material that explains what VoIP is in detail. The focus of this title is security only, and it's intended for system engineers, network administrators, security consultants and everyone else concerned in specifics related to VoIP security.

Park exemplifies an abundance of finest practices while studying and simulating actual threats such as Denial of Service (DoS), sniffing, spoofing and VoIP spam. The author also demonstrates details about authentication, encryption, transport and network layer security.

There's no individual device that can protect and whole VoIP network, the best you will be able to do is stay aware on the current vulnerabilities and deploy a consolidated solution which includes every one of your devices and architectures. Park presents you how to protect the enterprise VoIP network and in his examples uses Cisco products which is natural since this is a Cisco Press title.

The last part of "Voice over IP Security" talks on Lawful Interception (LI) and its execution. It's basically the interception of telecommunications by law enforcement agencies that we generally refer to as wiretapping. LI is grounded upon a government law requiring service providers to provide interception of user information and material related to the subject is very relevant for anyone dealing with a VoIP network.
