Book SynopsisWeb applications are increasingly using the query language GraphQL to share data, but the security of these useful APIs is lagging behind. Authored by the developers of widely used GraphQL security-testing tools, Black Hat GraphQL will teach you how to find and exploit flaws in this technology. Early chapters provide in-depth knowledge of GraphQL and its query language, as well as its potential security pitfalls. Readers will then be guided through setting up a hacking lab for targeting GraphQL applications using specialized GraphQL security tools. They will learn how to conduct offensive security tests against production GraphQL systems by gleaning information from GraphQL implementations during reconnaissance and probing them for vulnerabilities, like injections, information disclosure, and Denial of Service.Trade Review"Black Hat GraphQL is the best resource for anyone looking to test GraphQL for vulnerabilities. Not only did Aleks and Farhi write the book, but they also created the vulnerable application used in the books labs and created a suite of tools specially designed for analyzing weaknesses within GraphQL APIs. This is a must-read book for those in API security." —Corey Ball, author of Hacking APIs "This book brought me from zero to ‘incredibly dangerous’ in ten chapters. The authors break down complex topics, making them easy to understand, as well as outlining pros and cons of each feature, tool, and tactic. The book also has quite a bit of foreshadowing, mentioning how certain parts of GraphQL work, and how they will be exploited later. The authors share not only several hands-on labs, but several tools they created themselves and open-sourced for all to use. If you are going to be PenTesting GraphQL systems, or are charged with protecting such a system, this book is a must-have." —Tanya Janca, founder of We Hack Purple “With the increasing number of web platforms built on top of GraphQL, this book is an essential resource for all security practitioners. By covering both the basics and advanced topics, Nick and Dolev have created the ultimate guide to hacking GraphQL.”—Luca Carettoni, Doyensec "Knowing how to secure GraphQL is often the first question most users have after they have that "ah ha!" moment about how cool it is. While Apollo and others have written a lot of great documentation on best security practices, Black Hat GraphQL is the most comprehensive look from the other side. This is not just a book for red teamers or penetration testers. Any GraphQL developer will learn a lot here." —Tad Whitaker, Apollo GraphQL "I study my way up in cybersecurity, in part, through books. While many of the books I use don't actually bring something new to the table, Black Hat GraphQL is definitely an exception. My copy, believe it or not, is oversaturated with highlights. And that probably says it all." —Cristi Vlad, @CristiVlad25, cybersecurity researcherTable of ContentsForewordAcknowledgmentsIntroductionChapter 1: A Primer on GraphQLChapter 2: Setting Up a GraphQL Security LabChapter 3: The GraphQL Attack SurfaceChapter 4: ReconnaissanceChapter 5: Denial of ServiceChapter 6: Information DisclosureChapter 7: Authentication and Authorization BypassesChapter 8: InjectionChapter 9: Request Forgery and HijackingChapter 10: Disclosed Vulnerabilities and ExploitsAppendix A: GraphQL API Testing ChecklistAppendix B: GraphQL Security ResourcesIndex

Book SynopsisBuilding a successful product usually involves teams of people, and many choose the Scrum approach to aid in creating products that deliver the highest possible value. Implementing Scrum gives teams a collection of powerful ideas they can assemble to fit their needs and meet their goals. The ninety-four patterns contained within are elaborated nuggets of insight into Scruma (TM)s building blocks, how they work, and how to use them. They offer novices a roadmap for starting from scratch, yet they help intermediate practitioners fine-tune or fortify their Scrum implementations. Experienced practitioners can use the patterns and supporting explanations to get a better understanding of how the parts of Scrum complement each other to solve common problems in product development. The patterns are written in the well-known Alexandrian form, whose roots in architecture and design have enjoyed broad application in the software world. The form organizes each pattern so you can navigate directly to organizational design tradeoffs or jump to the solution or rationale that makes the solution work. The patterns flow together naturally through the context sections at their beginning and end. Learn everything you need to know to master and implement Scrum one step at a time'the agile way.
