In this 2 day workshop we will take a practical approach to adding cryptographic security to your applications.

Cryptography is generally regarded as being very hard to implement, but in this workshop we will show you that it is in fact very easy to do when you are given the right direction.

Generating cryptographically secure random numbers

Storing passwords with Password Based Key Derivation Functions

Using RSA and AES together to create a powerful and flexible encryption scheme

Hybrid Encryption with Authenticated Hashing for Integrity

Look at secure key management using Azure Key Vault

Look at some reference examples that use the principles from Day 1

This is a practical workshop where you will be playing around with all the techniques discussed. We aim to demystify the complexity around using robust encryption and you will leave this workshop with all the knowledge and skills to robustly secure your organisations data.

You will need to be a competent C# developer. You don't need to be an expert, but you need to be familiar with the basic C# constructs.

You will need to supply your own laptop that has:

Visual studio 2019 installed. Community edition is fine or Visual Studio for MAC

You can use JetBrains Rider if you wish on Windows / Linux

2 Days

Secure Programming for the Enterprise in .NET,  .NET Core and Future

Security

.NET

In this workshop, you discover best practices for building secure frontend applications. We investigate how to use and configure security mechanisms available in modern browsers. We explore what security measures are built into Angular and React, along with common mistakes that circumvent these protections. Additionally, we discuss scenarios that address frequent questions, including secure data storage in the browser and the use of OAuth 2.0 and OpenID Connect.


This course offers practical and immediately applicable security advice for architects and developers. Throughout the course, Philippe is available to answer any questions, including concrete scenarios applying to your own applications.
Concretely, we will cover the following topics:

Countering advanced XSS with Trusted Types

Using OAuth 2.0 and OpenID Connect in SPAs

Securing OAuth 2.0 tokens in JS frontends


This workshop consists of a mixture of lectures, demos, interactive quizzes, and hands-on labs. The lectures provide in-depth knowledge of attacks and defenses. The hands-on labs are conducted in a custom-built competitive training environment, allowing participants to gain hands-on experience with offensive and defensive technologies.



This security training specifically targets modern web developers. Anyone involved in building single-page applications (e.g., Angular, React) or managing development teams should be here. This training course is not just any training course. It is packed with in-depth and up-to-date content. We do not merely brush over a threat and defense but focus on the underlying cause and consequences. Why do we have this problem? Which mitigations are often used? Why are some ineffective? Which one is the current best practice? These are the questions that will be answered throughout the training.

To participate in this training, you should have development experience with single-page applications and the underlying APIs. Familiarity with the basics of security (e.g., simple XSS attacks) is helpful, but not required. The training will talk about Angular and React specifically, but also applies to other frameworks, such as EmberJS or Vue.js.

To participate in the lab sessions, participants need an internet-accessible laptop with a modern browser installed (E.g., Chrome, Firefox).

A builder’s guide to Single Page Application security

ASP.NET Core 5, gRPC, Protobuf, Visual Studio, .NET CLI, Docker, Kubernetes, services meshes, monitoring, distributed tracing

Day 1: Building gRPC applications in ASP.NET Core

Day 2: Security, Deployment and Observability

Service mesh (using Linkerd as an example)

Attendees will be expected to be familiar with .NET and C#, and bring a computer with the latest .NET Core 5 SDK and an IDE (VS2019, VS Code or Rider). For day two a local Docker installation that supports Kubernetes is strongly recommended (e.g. Docker Desktop for Windows or Mac).

Modern distributed systems with gRPC in ASP.NET Core 5

Here are a few of the topics and techniques covered in this workshop:

Record types – What are they? How do you use them? Why?

Nullable reference types – Moving towards immutability and avoiding null reference exceptions

Asynchronous Programming – Working with Streams and best practices

Pattern matching – Writing more beautiful and understandable code

Using Span<T> - Writing fast and memory efficient code

Each topic will be thoroughly covered, followed by exercises that allow you to understand and incorporate these language features in your projects. We will talk about how the application changes, benefits and drawbacks of applying the language features.

We’ll be discussing application design, leveraging new language features and try to answer any of the questions you might have!

This is a workshop you really don’t want to miss if you’re a C# developer in 2021!


Developing with C# in 2021

Programming Languages

In this workshop, you will learn how to simulate latency and failures in your web application and how to add strategies to deal with this. We will learn how changing the different parameters change the behavior of our application under load, and what trade-offs we ultimately must make.

We will start with introducing Polly, a resiliency and transient-fault-handling library for .NET applications.

We will then move on to using k6 for load testing a .NET Core web API. For resiliency strategies, we will use Polly and we will use Simmy for fault injection. This is red-green testing, but for performance and resiliency. As you work through the challenges, you will learn about service level indicators, service level objectives, and how to formulate and test such requirements. We will also work on some .NET specifics that we need to master regarding asynchronous programming to make sure the mechanisms work as intended.

In the last part of the workshop, we will focus on writing high-level tests in k6. We will share some of our experiences with such tests, and a simple process to help ensure system-level reliability and organizational coordination. You will gain a better understanding of k6, and reflect about some of the non-technical challenges of building reliable systems.

There are no prerequisites for the workshop, but you should have some experience building web applications to get the most out of the workshop. The workshop should be valuable to developers, testers and architects working with or with an interest in robustness and scalability.

Building and testing resilient services

Multi-platform, multi-client, and highly-mobile users bring a new set of challenges, so the approaches of the past are no longer appropriate for modern applications. This two-day workshop is your chance to dive into all things security related to these new technologies. Learn how to securely connect native and browser-based applications to your back-ends and integrate them with enterprise identity management systems as well as social identity providers and services.


.NET Core, ASP.NET Core, MVC, Web APIs, Claims, OpenID Connect, OAuth 2.0, WS-Federation, SAML, JSON Web Tokens, Single Sign-on and off, Federation, Delegation, Home Realm, Discovery, CORS

Social Logins (e.g. Google, Facebook, Twitter, etc.)


Attendees will need to bring a computer with the latest .NET Core SDK and the IDE of your choice (e.g. Visual Studio) installed.

Identity & Access Control for modern Applications and APIs using ASP.NET Core 5

This 2-day workshop will quickly progress you from Blazor fundamentals through to creating rich interactive UI experiences using the more advanced framework features. The objective of this workshop is that attendees walk away with a solid understanding of the Blazor framework as well as practical experience of building a real application with it.

Leveraging browser APIs and existing JavaScript libraries

This course assumes attendees are familiar with .NET, C# and web technologies such as HTML, CSS and JavaScript. Attendees will also need to bring a laptop with the following:

An IDE such as Visual Studio 2019, Visual Studio for Mac or JetBrains Rider. VS Code can also be used.

Blazor Workshop

In this tutorial, we will look at why asynchronous messaging is often the preferred solution to the problems of integrating and distributed solution, and look at the implementation of common messaging patterns.

If you have ever been put off moving from RPC-based solutions to messaging because of the need to learn how to implement messaging based solutions, this workshop will get you started. if you have been using messaging but want to gain a firmer understanding

The session will be a hands-on introduction and take you from simple messaging scenarios like "Hello World" through to more complex ideas like routing, brokers, and publish-subscribe.

Day 1: Messaging Architectures and Simple Patterns

Day 2: Distributed Systems Advanced Patterns

There will be hands on coding exercises in .NET and Python enabling you to implement simple and more complex messaging scenarios.


We will use Rabbit MQ for examples. You need not have the latter installed on your machine, but you should have Docker installed on your machine, as exercises will use Docker Compose.This is a Bring Your Own Device (BYOD) course. At BYOD courses delegates are required to bring their own laptop with the necessary software installed

Practical Messaging Workshop

DevOps

Python

In this workshop, we'll share some framing for microservice architectures that explore the various forces that can drive the design and evolution of microservices, and then you'll participate in a series of interactive architectural kata exercises to put your newfound knowledge to the test. Afterwards, you'll have a series of tools to take back to your own organisations to put into practice.

Understand what makes a good microservice

Learn how to use concepts from domain-driven design to define service boundaries

Understand how to plan and manage a migration from a monolith to the microservice architecture

Understand how technical choices can impact the architecture itself

Learn about managing change and governance in a microservice environment

This is a participatory workshop. You won't get to just sit there and watch – the more you participate in the workshop, the more you'll get out!
