This workshop is here to give you the skills you need to make your APIs secure. We're going to think like an attacker to test APIs and like a defender to figure out the best ways to protect them. With deep-dive talks, real-world demos, fun quizzes, and hands-on labs, you'll learn how to lock down your APIs.
During this hands-on training, we'll explore:

The security model of API-based web applications

Recognizing and addressing authorization failures

Understanding Broken Object Property Level Authorization (BOPLA)

Fixing Broken Object Level Authorization (BOLA)

Testing the security of APIs that use JWTs

Best practices for making JWTs secure in modern APIs

Identifying, exploiting, and fixing Server-Side Request Forgery (SSRF) issues

Understanding Cross-Origin Resource Sharing (CORS)

Configuring secure CORS policies for various use cases

Tracking user authentication securely with sessions or tokens

Relying on OAuth 2.0/2.1 for securing APIs

Q & A throughout the workshop to clear up any doubts


This workshop is about more than theory. We're all about giving you practical security tips you can use right away as an API developer. We dig into the root causes of API threats and how to handle them. We don't just skim the surface of problems and solutions - we get into the why's and how's, looking at common fixes, why some fall short, and which ones are currently the best way to go.
By the end of this workshop, you'll be up-to-speed on the best practices for API security. You'll also leave with a handy list of steps to check and boost the security of your applications.




This training is perfect for developers and architects who work a lot with APIs. If your role involves building, testing, or designing modern apps, this workshop will give you a thorough, up-to-date understanding of the best ways to keep things secure. We'll often use NodeJS, Flask, and Spring Boot in our code examples and demos, but you'll easily be able to apply what you learn to other languages and frameworks.




These testimonials from previous workshops give you a good idea of what to expect:

Trainer is great and an expert in the domain. All of the topics are very relevant. Practical examples for most of the topics. Excellent communication and addressing of questions.

Even though the topic is broad, there was no single moment where my focus went astray. Philippe talks in a way to keep you interested to listen to him.

I liked the the pleasant and relaxed way of speaking and the fresh style of presentation of this kind of dry stuff :)

Philippe is a friendly and knowledgable trainer and delivered an interesting course that was well presented. Questions were answered promptly and in a detailed way.


To participate in this training, you should have some experience with building API-based applications. Knowledge of application security can be helpful, but is not required.

What if it didn't have to be like that? What if you could write code that never fails? Believe it or not - you can.

Functional programming is a style of writing code that has been around since the 1960s, and has been becoming increasingly popular in recent years, with the advent of technologies like Serverless and async.

It's a style of code that removes side effects and unpredictable behaviour from your applications, making them just about impossible to break in production.

It enables nearly 100% unit test coverage, increasing the quality of the code that you deploy.

It doesn't have issues of resource contention or race conditions relating to state, making it ideal for asynchronous & distributed processing of data.

All of this is accomplished with out-of-the-box C#. No need to pay for new software licences or install additional software packages.

Using the techniques from this workshop, you will be able to immediately improve the quality of your production code, without it costing anything!

Write Code that NEVER Fails - Functional Programming With C#

Identity & Access Control for modern Applications and APIs using ASP.NET 9

In this workshop, we will design APIs with respect to the non-functional requirements that are paramount to any serious application running in production.

We will cover the design process of several API types, including REST, and then we will transition towards messaging, always with an eye on the Cloud.

This is a hands-on workshop, so be prepared to write code! We will start by designing an API with all the production-ready quality attributes. Then, we expand the feature set so that, in the end, we have an overview of the steps we have to take to have robust APIs that are reliable and capable to effortlessly manage heavy loads without breaking a sweat.

By the end of the workshop, you will know how you can evolve your architecture from simple to complex that has the most sought-after quality attributes, from RESTful to messaging-based. We will deep dive into a new world that covers queues, topics, brokers, different abstractions, and patterns like outboxes or sagas specific to distributed systems.

We will see what the usual steps are to do that and what transformations we have to make in our architecture to accommodate everything.

This is a hands-on workshop, so be prepared to write code!


In this section we delve into intricacies of REST-based APIs, the client/server nature of it and we explore the decision-making process behind choosing REST, by offering a detailed guide to the API design process, documenting and the most common usage scenarios.

Media-type selection, design & custom media types


This section we cover gRPC and we outline the RPC API design process. We start by exposing and defining operations, particularities of consuming these APIs and document them. This succinctly summarizes the key components covered in this part, providing an overview of the gRPC protocol, considerations for RPC, and the step-by-step process for designing RPC APIs.


In this section we take our previously designed API, and we start doing the necessary changes to make use of asynchronous messaging.

We deep dive into a new world that covers queues, topics, message brokers, different abstraction and patterns and we will see what changes are needed to adapt our previous architecture.

In this section we will see how we can introduce patterns like Outbox, Competing consumers, Sagas, Routing Slips and learn what we gain from using them, as well as looking at how we can monitor our system.

Versioning strategies for backwards and forward compatibility

Designing APIs

This workshop will challenge that assumption. It will show you how Rust isn't just a low-level systems programming language that requires a deep computer science background and how you can use it to build modern business applications. Throughout the workshop we'll take a practical approach to learning Rust. Instead of focusing on language internals, you'll learn practical skills to help you be a productive Rust developer. Along the way parallels will be drawn with building applications in .NET to help you transfer your existing knowledge to working with Rust.

Tools


This workshop teaches advanced, cutting edge techniques based on ongoing research that are designed to identify and decrease risk, improve confidence in decision making and protect your architecture when the domain is characterized by uncertainty.

The workshop introduces ideas on the philosophy of architecture, forcing participants to think outside of the technology and relate decision making to markets, culture, economic and societal concerns. It teaches practical techniques in stressor analysis and the use of matrices to make component decisions and gives participants the chance to work with these techniques in labs and groups.


This workshop is suitable for senior developers who want a head start into the world of architecture, for teams embarking on large, risk filled projects, and for seasoned architects seeking new techniques. It has also been successful in unting teams around a common definition of architecture.

Machine Learning

These business processes are usually non-trivial, exceed the boundaries of a single method- or service invocation, and require us to redefine certain concepts, including coupling and time.

If you've been exposed to the basic building blocks of messaging and want to transition your system from a collection of meaningless and often highly-coupled service-to-service calls to one composed of carefully designed processes that reflect your business domain, this workshop is for you. Throughout this workshop, we'll discuss numerous real-world scenarios based on years of experience in the banking and retail domains, making you better equipped to recognize patterns in whichever domain you may be working on.


Have a foundational understanding of messaging as an architectural style and the benefits it offers.

Understand the basic message-based communication patterns, including request-reply and publish-subscribe.

Have experience using message brokers, such as Azure Service Bus, RabbitMQ, or other queuing or broker technologies.


Throughout this workshop, you’ll learn to:

How to identify complex business processes within your domain

Techniques to help identify the right service boundaries

Coordinate complex business processes with orchestration and choreography

Engage in thorough tradeoff analysis to get to the right design

Manage requirements that need to occur at different points in time

Test complex, long-running processes in an automated way

Leverage observability to troubleshoot issues where they matter most: in production!

Throughout this workshop, we'll divide into smaller groups for design exercises that require nothing more than your imagination and something to write with. Later, we'll switch gears and get more hands-on with some coding exercises to bring those ideas to life using C#.

Join me and unlock the secrets of messaging's real-world superpowers!

In addition, it's helpful to have accounts ready to use for:

Unless you’re working in the front end on a daily basis, it’s hard to keep up to date and ensure that your front end is still modern. This hands on workshop covers modern front end fundamentals, enabling you to create a layout and components without the need for any third party code. You learn core concepts to make your project more accessible without having to write complex code, take shortcuts or deal with browser specific implementations.

Once that is done, we move on to testing our application, making sure that our accessibility improvements are there, watching for any unintended changes & making sure that the application works as it’s supposed to. Through automated tools that can be implemented as part of a deployment pipeline, to manual tools to check on the fly, there are plenty of options to ensure the front end is being tested as thoroughly as the back end.

After the tests are written, we’ll then integrate them as part of an approval and deployment pipeline. Automating the tests for pull requests, running through GitHub actions and ensuring that code is fully tested before it reaches the production branch of your repo.

Accessibility Testing (automated and manual tests)


This workshop involves using various testing tools, and involves getting started with the tools from the beginning without any prior experience. Where possible, open source tools are used.


This workshop is aimed at anyone who works with front end code on a regular basis and needs to keep up to date with the constantly changing world of front end development. Even if you're just brushing up on your skills, this is the workshop for you.


Some experience with front end code desirable, a basic understanding of HTML and CSS as fundamental concepts won't be covered. Some experience with JavaScript is also useful as the tests will be written in JavaScript.
