Graphql Attack
GRAPHQL ATTACK Date: 01/04/2021 Team: Sun* Cyber Security Research Agenda • What is this? • REST vs GraphQL • Basic Blocks • Query • Mutation • How to test What is the GraphQL? GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015. • Powerful & Flexible o Leaves most other decisions to the API designer o GraphQL offers no requirements for the network, authorization, or pagination. Sun * Cyber Security Team 1 REST vs GraphQL Over the past decade, REST has become the standard (yet a fuzzy one) for designing web APIs. It offers some great ideas, such as stateless servers and structured access to resources. However, REST APIs have shown to be too inflexible to keep up with the rapidly changing requirements of the clients that access them. GraphQL was developed to cope with the need for more flexibility and efficiency! It solves many of the shortcomings and inefficiencies that developers experience when interacting with REST APIs. REST GraphQL • Multi endpoint • Only 1 endpoint • Over fetching/Under fetching • Fetch only what you need • Coupling with front-end • API change do not affect front-end • Filter down the data • Strong schema and types • Perform waterfall requests for • Receive exactly what you ask for related data • No aggregating or filtering data • Aggregate the data yourself Sun * Cyber Security Team 2 Basic blocks Schemas and Types Sun * Cyber Security Team 3 Schemas and Types (2) GraphQL Query Sun * Cyber Security Team 4 Queries • Arguments: If the only thing we could do was traverse objects and their fields, GraphQL would already be a very useful language for data fetching. -

By Andreas Grabner — DevOps Activist FreeBSD: Code, Community and Collaboration 17:55 GMT-3 / 16:55 GMT -4 / 15:55 GMT -5 / 13:55 GMT -7 The FreeBSD Open Source Operating System is one of the oldest, largest, and most successful open source projects, with a long history of innovation. FreeBSD descended from Berkeley Unix back in the early ’90s, with its lineage dating back 50 years to the original UNIX. It’s known for its reliability, stability, and advanced networking and performance. Deb will take you through its long history and highlight some of the features that set FreeBSD apart from other operating systems. She’ll describe how the FreeBSD Project works and how you can contribute to the Project. She will point out some of the differences between FreeBSD and Linux, and share why individuals and companies use FreeBSD. -

Precompiler Session 01 - Tuesday 8:00 Machine Learning: Taking Your ML Models to Android and Ios Wes Eklund
PreCompiler Session 01 - Tuesday 8:00 Machine Learning: Taking your ML Models to Android and iOS Wes Eklund Once you've developed a kickass Machine Learning model, you need a way to get that model to your computing devices (phones) to start doing your predictions! Most Machine Learning projects in production will 'train' the model on cloud servers, then 'deploy' the model to an API server or mobile device. This session will introduce the attendee on using TensorFlow Serving and Apple CoreML to deploy Machine Learning models to a mobile app. Prerequisites: Download Here Build a Natural Language Slack Bot for your Dev Team Michael Perry Many project teams use Slack as a means of communication with one another. Why not also use it to communicate with your infrastructure? Invite a helper into your conversation that can perform routine tasks tirelessly, conversationally, and interactively. In this 4 hour workshop, you will build a Slack bot that understands natural language and integrates with your DevOps pipeline. You will use the Slack Events API to receive messages, and the Slack Web API to send them. You will use LUIS to interpret language and extract intent. You will execute actions against the Visual Studio Team Services Web API in response to user requests, and subscribe to Webhooks to notify your team of important events. In the end, you will have a new member of your team who can help you with your build and release pipeline. Workshop outline: Slack API Authorization - OAuth and API key verification Events API - respond to posts Web
