Chapter 1: Approaching a Penetration Test Using Metasploit
Penetration testing is an intentional attack on a computer-based system where the intention is to find vulnerabilities, security weaknesses, and certify whether a system is secure. A penetration test allows an organization to understand their security posture in terms of whether it is vulnerable to an attack, whether the implemented security is enough to oppose any invasion, which security controls can be bypassed, and much more. Hence, a penetration test focuses on improving the security posture of an organization.
Achieving success in a penetration test largely depends on using the right set of tools and techniques. A penetration tester must choose the right set of tools and methodologies to complete a test. While talking about the best tools for penetration testing, the first one that comes to mind is Metasploit. It is considered one of the most effective auditing tools to carry out penetration testing today. Metasploit offers a wide variety of exploits, an excellent exploit development environment, information gathering and web testing capabilities, and much more.
This book has been written so that it will not only cover the frontend perspectives of Metasploit, but also focus on the development and customization of the framework. With the launch of Metasploit 5.0, Metasploit has recently undergone numerous changes, which brought an array of new capabilities and features, all of which we will discuss in the upcoming chapters. This book assumes that you have basic knowledge of the Metasploit framework. However, some of the sections of this book will help you recall the basics as well.
While covering Metasploit from the very basics to the elite level, we will stick to a step-by-step approach, as shown in the following diagram:
Figure 1.1 – Chapter overview
This chapter will help you recall the basics of penetration testing and Metasploit, which will help you warm up to the pace of this book.
In this chapter, you will learn about the following topics:
- Organizing a penetration test
- Mounting the environment
- Conducting a penetration test with Metasploit
- Benefits of penetration testing using Metasploit
- Case study – reaching the domain controller
An important point to take note of here is that you won't become an expert penetration tester in a single day. It takes practice, familiarization with the work environment, the ability to perform in critical situations, and most importantly, an understanding of how you have to cycle through the various stages of a penetration test.
