You should know the basics of operating a Linux environment and have some exposure to security technologies and tools.What You Will LearnSet up a penetration testing laboratory in a secure wayFind out what information is useful to gather when performing penetration tests and where to look for itUse crawlers and spiders to investigate an entire website in minutesDiscover security vulnerabilities in web applications in the web browser and using command-line toolsImprove your testing efficiency with the use of automated vulnerability scannersExploit vulnerabilities that require a complex setup, run custom-made exploits, and prepare for extraordinary scenariosSet up Man in the Middle attacks and use them to identify and exploit security flaws within the communication between users and the web serverCreate a malicious site that will find and exploit vulnerabilities in the user's web browserRepair the most common web vulnerabilities and understand how to prevent them becoming a threat to a site's securityIn DetailWeb applications are a huge point of attack for malicious hackers and a critical area for security professionals and penetration testers to lock down and secure. Kali Linux is a Linux-based penetration testing platform and operating system that provides a huge array of testing tools, many of which can be used specifically to execute web penetration testing.This book will teach you, in the form step-by-step recipes, how to detect a wide array of vulnerabilities, exploit them to analyze their consequences, and ultimately buffer attackable surfaces so applications are more secure, for you and your users.Starting from the setup of a testing laboratory, this book will give you the skills you need to cover every stage of a penetration test: from gathering information about the system and the application to identifying vulnerabilities through manual testing and the use of vulnerability scanners to both basic and advanced exploitation techniques that may lead to a full system compromise. Finally, we will put this into the context of OWASP and the top 10 web application vulnerabilities you are most likely to encounter, equipping you with the ability to combat them effectively. By the end of the book, you will have the required skills to identify, exploit, and prevent web application vulnerabilities.Style and approachTaking a recipe-based approach to web security, this book has been designed to cover each stage of a penetration test, with de*ions on how tools work and why certain programming or configuration practices can become security vulnerabilities that may put a whole system, or network, at risk. Each topic is presented as a sequence of tasks and contains a proper explanation of why each task is performed and what it accomplishes.

This book is great for developers, quality assurance engineers, testers, and test managers new to Apache JMeter, or those who are looking to get a good grounding in how to effectively use and become proficient with JMeter. No prior testing experience is required.

This book is for web developers and designers who work with React.js and JavaScript and who are new to unit testing and automation. It's assumed that you have a basic knowledge of JavaScript and HTML.

Programmers new to the Raspberry Pi and novice programmers with little to no experience with micro board computing will find the book useful. A basic knowledge of programming languages in general will prove useful for a better understanding of the topics.

If you are a Java developer or a manager who has experience with Apache Maven and want to extend your knowledge, then this is the ideal book for you. Apache Maven Cookbook is for those who want to learn how Apache Maven can be used for build automation. It is also meant for those familiar with Apache Maven, but want to understand the finer nuances of Maven and solve specific problems.

This book is for kids who wish to develop games and applications using the Raspberry Pi. No prior experience in programming is necessary; you need only a Raspberry Pi and the required peripherals.
