Overview of this book

The book starts with a hands-on Day 1 chapter, covering the basics of the Metasploit framework and preparing the readers for a self-completion exercise at the end of every chapter. The Day 2 chapter dives deep into the use of scanning and fingerprinting services with Metasploit while helping the readers to modify existing modules according to their needs. Following on from the previous chapter, Day 3 will focus on exploiting various types of service and client-side exploitation while Day 4 will focus on post-exploitation, and writing quick scripts that helps with gathering the required information from the exploited systems. The Day 5 chapter presents the reader with the techniques involved in scanning and exploiting various services, such as databases, mobile devices, and VOIP. The Day 6 chapter prepares the reader to speed up and integrate Metasploit with leading industry tools for penetration testing. Finally, Day 7 brings in sophisticated attack vectors and challenges based on the user’s preparation over the past six days and ends with a Metasploit challenge to solve.

Testing Voice over Internet Protocol services

Let us now focus on testing Voice over Internet Protocol (VoIP)-enabled services and see how we can check for various flaws that might affect VoIP services.

VoIP fundamentals

VoIP is a much less costly technology when compared to the traditional telephonic services. VoIP provides much more flexibility than traditional telephony in terms of telecommunication, and offers various features, such as multiple extensions, caller ID services, logging, the recording of each call made, and so on. Some companies now have their Private Branch exchange (PBX) on IP-enabled phones these days.

The traditional and still-present telephonic system is still vulnerable to interception through physical access, such that if an attacker alters the connection of a phone line and attaches their transmitter, they will be able to make and receive calls to their device and can enjoy Internet and fax services.

However, in the case of VoIP services, we can compromise security...
