Description

Introduction 
Security is a fundamental aspect of web development, and ASP.NET Core offers powerful tools to ensure that your applications are secure. In this course, you will learn how to implement authentication and authorization in your ASP.NET Core applications, which are essential for protecting sensitive data and controlling access to resources. We will cover various authentication strategies such as cookie-based authentication, JWT tokens, and third-party authentication services. Additionally, we will dive into authorization techniques, including role-based and policy-based access control. By the end of this course, you will have the skills to secure your web applications and manage user access effectively.

Prerequisites

• Basic understanding of web development with ASP.NET Core
• Familiarity with MVC architecture and the basics of web security
• Experience working with C# and .NET Core
