Great commericial penetration testing tools can be very expensive and, depending on the situation, #xA0;hard to use or of questionable accuracy. This book helps solve both of these problems. First, keeping budgetary restrictions in mind, this book covers open source,#xA0;no-cost penetration testing tools that do a great job and can be modified by the user for each situation. Second, many tools, even ones that cost thousands of dollars, do not come with any type of instruction on how and in which situations the penetration tester can best use them. Penetration Tester's Open Source Toolkit, Third Edition, goes a step beyond what is available for so-called instructions on these tools and expands upon them so that a professional can get the most accurate and in-depth test results possible. Real-life scenarios are a major focus so that the reader knows which tool to use and how to use it for a variety of situations.
