    OWASP Top 10

    One of the flagship projects for the Open Web Application Security Project (OWASP.org) is its top ten list. This list has been published about every three years since 2003. There have been some realignment of what it was a list of through the years, but in terms of the risks that applications commonly have, it is largely unchanged.

    The latest list is from 2017. As we cover the list in subsequent topics, where possible, we will explore the vulnerability from the attackers point of view, examine the code flaw, and mitigate the risk with countermeasures. Some of the items can be caused by a number of different code flaws or might not be specifically code related.

  • Installing Visual Studio8:46

    You will need Visual Studio 2019 with the ASP.Net web development workload installed on your system to participate in labs. Even if you already have VS installed, please take a look at the video for important information about how we will be using it in the class.

Description

Web applications are under constant attack, and developers are expected to understand how to identify, prevent, and mitigate the most common vulnerabilities. This course teaches you how to secure ASP.NET and ASP.NET Core applications using industry‑standard practices and the OWASP Top 10, the globally recognized benchmark for web application security.

You’ll learn how real‑world attacks work, how to exploit vulnerable code in a safe environment, and—most importantly—how to fix those vulnerabilities using secure coding techniques. Through hands‑on labs, practical examples, and clear explanations, you’ll build the skills needed to design and develop applications that are secure by default.

This course has been delivered to thousands of developers worldwide, including teams at major corporations, government agencies, and the military. Microsoft uses Chuck’s courses internally to train their own developers, and the curriculum has evolved over two decades to reflect today’s modern security challenges.

Whether you’re a beginner developer or an experienced engineer looking to strengthen your security mindset, this course will help you understand the risks, avoid common mistakes, and build safer, more resilient ASP.NET applications.

What You’ll Learn

  • Understand and mitigate the OWASP Top 10 vulnerabilities

  • Prevent SQL Injection, XPath Injection, and command injection

  • Implement secure authentication and authorization using Identity

  • Protect applications from XSS, CSRF, XXE, and broken access control

  • Avoid insecure deserialization and unsafe component usage

  • Apply secure‑by‑default design principles in ASP.NET Core

  • Strengthen logging, monitoring, and error‑handling practices

  • Build secure business‑tier logic and validate user input effectively

(All rewritten from your original bullet list, but clearer and more SEO‑friendly.)

Why This Course Stands Out

  • Taught by an instructor whose courses are used by Microsoft to train developers

  • Hands‑on labs with real code, real vulnerabilities, and real fixes

  • Updated for modern ASP.NET Core and current OWASP guidance

  • Designed for developers who want practical, actionable skills—not theory

Who This Course Is For

  • ASP.NET and ASP.NET Core developers

  • Software engineers who want to build secure applications

  • Students preparing for cybersecurity or secure‑coding roles

  • Teams adopting secure‑by‑design development practices

  • Anyone responsible for reducing risk in web applications

Who this course is for:

  • ASP Net Developers
  • C# Developers
