JWT Authentication with Advanced Features

In this project, we implement Authentication using JWT Token with advanced features, without relying on any third-party packages other than the one provided by Microsoft.

Overview

JWT (JSON Web Tokens) is a widely used standard for implementing authentication and authorization in web applications. In this project, we aim to enhance the JWT authentication process by implementing the following advanced features:

User Account Lockout:

Implement account lockout policies to prevent brute-force attacks. After a specified number of failed login attempts, a user's account should be temporarily locked.

Password Complexity Requirements:

Enforce strong password policies, including requirements for minimum length, complexity (e.g., special characters, uppercase letters), and password expiration policies.

Token Revocation:

-Implement the ability to revoke JWT tokens in case of compromised accounts or lost devices. Revoked tokens should not be accepted, even if they are still within their expiration period.

Access Control Lists (ACLs):

Implement fine-grained access control based on user roles and permissions. Define access control lists for different resources and endpoints, allowing or denying access based on user roles.

Implementation Steps

To implement JWT Authentication with these advanced features in your project, follow these steps:

Install the Microsoft JWT Package:

Add the Microsoft.AspNetCore.Authentication.JwtBearer package to your project using NuGet Package Manager or by adding it to your .csproj file.

Configure JWT Authentication:

In your Startup.cs file, configure JWT authentication with the advanced features mentioned above. Customize token validation, user account management, and access control policies accordingly.

Account Lockout:

Implement account lockout policies and mechanisms to track failed login attempts. Temporarily lock user accounts that exceed the maximum allowed failed attempts.

Password Complexity and Expiry:

Enforce strong password complexity requirements and implement password expiration policies. Provide mechanisms for users to change their passwords securely.

Token Revocation:

Develop a token revocation system that allows users to revoke tokens and ensures that revoked tokens are not accepted during subsequent authentication.

Access Control Lists (ACLs):

Define access control lists for your application's resources and endpoints. Implement middleware or attribute-based access control to enforce authorization based on user roles and permissions.

Example Usage

Here's an example of how to use JWT Authentication with advanced features in your ASP.NET Core application:

[Authorize(Roles = "Admin")]
public class AdminController : ControllerBase
{
    [HttpGet("admin-dashboard")]
    public IActionResult AdminDashboard()
    {
        // Your admin dashboard logic here
    }
}
