Book Description

Tools used for penetration testing are often purchased or downloaded from the Internet. Each tool is based on a programming language such as Perl, Python, or Ruby. If a penetration tester wants to extend, augment, or change the functionality of a tool to perform a test differently than the default configuration, the tester must know the basics of coding for the related programming language. Coding for Penetration Testers provides the reader with an understanding of the scripting languages that are commonly used when developing tools for penetration testing. It also guides the reader through specific examples of custom tool development and the situations where such tools might be used. While developing a better understanding of each language, the reader is guided through real-world scenarios and tool development that can be incorporated into a tester’s toolkit.

Review
“Penetration testing is a profession that requires the mastery of dozens of tools; every job poses challenges that require these tools to be mixed, matched, and automated. The master penetration tester not only excels at using his or her toolbox, but also expands it with custom scripts and unique programs to solve the challenge of the day. This book provides a solid introduction to custom scripting and tool development, using multiple languages, with a penetration tester’s goals in mind. This background can transform penetration testing from a manual, often repetitive task, to an efficient process that is not just faster, but also more accurate and consistent across large engagements.”

Book Description

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it’s an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards.

bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell — the bash shell — and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems — rather than have their systems manage them.
