ASP.NET Core 5 Secure Coding Cookbook

By: Roman Canlas

Overview of this book

ASP.NET Core developers are often presented with security test results showing the vulnerabilities found in their web apps. While the report may provide some high-level fix suggestions, it does not specify the exact steps that you need to take to resolve or fix weaknesses discovered by these tests. In ASP.NET Secure Coding Cookbook, you’ll start by learning the fundamental concepts of secure coding and then gradually progress to identifying common web app vulnerabilities in code. As you progress, you’ll cover recipes for fixing security misconfigurations in ASP.NET Core web apps. The book further demonstrates how you can resolve different types of Cross-Site Scripting. A dedicated section also takes you through fixing miscellaneous vulnerabilities that are no longer in the OWASP Top 10 list. This book features a recipe-style format, with each recipe containing sample unsecure code that presents the problem and corresponding solutions to eliminate the security bug. You’ll be able to follow along with each step of the exercise and use the accompanying sample ASP.NET Core solution to practice writing secure code. By the end of this book, you’ll be able to identify unsecure code causing different security flaws in ASP.NET Core web apps and you’ll have gained hands-on experience in removing vulnerabilities and security defects from your code.

Technical requirements

This book was written and designed to be used with Visual Studio Code, Git, and .NET 5.0. The code examples in these recipes will be presented in ASP.NET Core Razor pages. The sample solution also uses SQLite as the database engine for a more simplified setup. The complete code examples for this chapter are available at https://github.com/PacktPublishing/ASP.NET-Core-Secure-Coding-Cookbook/tree/main/Chapter13.

Getting ready

For the recipes in this chapter, we will need a sample Online Banking app.

Open the command shell and download the sample Online Banking app by cloning the ASP.NET Secure Coding Cookbook repository, as follows:

git clone https://github.com/PacktPublishing/ASP.NET-Core-Secure-Coding-Cookbook.git

Run the sample app to verify that there are no build or compile errors. In your command shell, navigate to the sample app folder at \Chapter13\exception-handling\before\OnlineBankingApp and run the following command:

dotnet build
