Setup and Installation of Zen for Dotnet

This guide will walk you through installing and setting up Zen by Aikido for your application. Follow the steps below to protect your application.

We have first class support for multiple frameworks and database drivers, for the full list check our README on GitHub.

1. Install Zen by Aikido

Zen for Dotnet comes as a NuGet packages for Core and Framework that need to be installed together with your code so your application can be protected.

Install the package from NuGet:

dotnet add package Aikido.Zen.DotNetCore

Configure your application to initiate the Zen firewall.

2. Create an app in the dashboard and generate a token

1. Go to the Zen section in Aikido.

2. Click on Add app.

3. Choose a name for your app and click Generate token.

4. Copy the generated token.

3. Start Zen in dry / detection-only mode

Set the token as an environment variable, in appsettings.json or Web.config appSettings depending on your environment.

{
  "Aikido": {
    "AikidoToken": "your-api-key"
  }
}

Start your app in dry mode AIKIDO_BLOCK=false to ensure it works as expected without blocking any requests:

Tip: You can use AIKIDO_DEBUG=true to enable debug mode (To verify that you set AIKIDO_TOKEN correctly)

4. Test your app

Browse to your application and perform a couple of actions or open a couple of pages. Zen will automatically discover the routes in your application.

5. Enable Rate limiting and User blocking

Enable additional features like Rate limiting and User blocking from within your code. Check out these examples below. Keep in mind that your specific setup might need adjustments based on your framework and configuration.

.UseRouting()
.Use((context, next) =>
{
    // Identify users to the Zen platform
    var id = context.User?.Identity?.Name ?? "-1";
    var name = context.User?.Identity?.Name ?? "Anonymous";
    if (!string.IsNullOrEmpty(id))
        Zen.SetUser(id, name, context);
    return next();
})
.UseZenFireWall()

6. Setup rate limiting in the dashboard

If you've added the rate-limiting feature, you can test it out by logging in to your Aikido account and navigating to the Zen dashboard. Click on the created app and check the Events tab to verify that a “started” event was recorded:

To protect a route from brute force attacks, set up rate limiting in the Aikido Dashboard:

1. Click on the created app.

2. Go to the Routes tab.

3. Find the route you would like to limit and click Setup rate limiting.

4. Follow the instructions to configure the rate limit (e.g., 5 requests per minute).

7. Verify Rate Limiting

Start your app and try to access the route you've rate limited 5 times within a minute. After the fifth attempt, you should receive a rate limit error:

You are rate limited by Aikido firewall. (Your IP: 1.2.3.4)
