By: Sagar Rahalkar, Nipun Jaswal

Overview of this book

Metasploit is a popular penetration testing framework that has one of the largest exploit databases around. This book will show you exactly how to prepare yourself against the attacks you will face every day by simulating real-world possibilities. This learning path will begin by introducing you to Metasploit and its functionalities. You will learn how to set up and configure Metasploit on various platforms to create a virtual test environment. You will also get your hands on various tools and components and get hands-on experience with carrying out client-side attacks. In the next part of this learning path, you’ll develop the ability to perform testing on various services such as SCADA, databases, IoT, mobile, tablets, and many more services. After this training, we jump into real-world sophisticated scenarios where performing penetration tests are a challenge. With real-life case studies, we take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit framework. The final instalment of your learning journey will be covered through a bootcamp approach. You will be able to bring together the learning together and speed up and integrate Metasploit with leading industry tools for penetration testing. You’ll finish by working on challenges based on user’s preparation and work towards solving the challenge.

Testing VOIP services


Let's now focus on testing VOIP-enabled services and see how we can check for various flaws that might affect VOIP services.

VOIP fundamentals

Voice Over Internet Protocol (VOIP) is a much less costly technology when compared to the traditional telephonic services. VOIP provides much more flexibility than the traditional ones in terms of telecommunication and offers various features, such as multiple extensions, caller ID services, logging, recording of each call made, and so on. Various companies have launched their Private Branch eXchange (PBX) on IP-enabled phones.

The traditional and the present telephonic systems are still vulnerable to interception through physical access, so 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 the victim's device and enjoy Internet and fax services.

However, in the case of VOIP services, we can compromise security without going on to the wires. Nevertheless...
