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.

Book SynopsisKubernetes Quickly is a clear and practical beginner's guide that shows you just how easy, flexible, and cost-effective it can be to make the switch to Kubernetes deployment even for small to medium-sized applications. Kubernetes Quickly is a hands-on guide to taking your first steps into Kubernetes using the powerful Google Kubernetes Engine service. It lays out a map for taking an application, containerizing it, and then deploying it onto Kubernetes. You'll learn best practice techniques for a stable and long-term Kubernetes deployment, including scaling and capacity planning, saving money by optimizing resource consumption, and tricks to make your day-to-day monitoring easier such as debugging code in the cloud. You don't need to incur huge costs or have the manpower of an enterprise organization to get a productivity boost from Kubernetes. By organizing your application component into containerized components and automating tasks like scaling and replication, Kubernetes keeps your apps running smoothly. Cloud-based Kubernetes services like Google Kubernetes Engine(GKE) reduce OS issues, simplify operations, and give you the freedom to use whatever software stack you want. If you've heard that switching to Kubernetesis complex, good news—Kubernetes for Developers will show you how it can be done without a time-consuming rebuild. Using examples from the Google Kubernetes Engine created by the team who invented Kubernetes itself, you'll learn to set up future-proof application deployments that scale to handle ever-growing and complex workloads.Trade Review“Whether you are using kubernetes now or thinking of using kubernetes in the future, there is no better way to expand your knowledge than this book. “ Becky Huett “Excellent introductory text for Kubernetes that augments the Kubernetes documentation with best practice tips and great tool recommendations.” Robert Kielty “This is an excellent introduction to Kubernetes in particular and Cloud deployments in general.” Juan Jimenez “Get ready to be taken from the old world to the new. It won't hurt to give this book another read-over before you deploy your service into production!” Chase Sillevis “An excellent read for a newbie who wants to get closer to Kubernetes.” Giuliano Latini

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.
