HTTPS, SSL Certificates and Security Best Practices — ShopNest
Article 35 of 75 · Module 4: Authentication & Security · ShopNest Production Deployment Security
Target keyword: https ssl asp.net core · Read time: ~28 min · .NET: 8 / 9 · Project: ShopNest Production Deployment Security

Introduction

Production ShopNest must enforce HTTPS, configure SSL certificates, set CORS for APIs, and apply rate limiting — this lesson covers dev certificates through Azure/IIS deployment.

After this article you will

  • Trust dev HTTPS certificate and enforce redirect
  • Configure HSTS and CSP headers
  • Understand Let's Encrypt vs commercial certs
  • Set CORS policy for ShopNest API
  • Enable .NET 8 rate limiting middleware

Prerequisites

Concept deep-dive

// Program.cs — production security baseline
if (!app.Environment.IsDevelopment())
{
    app.UseHsts();
    app.UseHttpsRedirection();
}

app.Use(async (ctx, next) =>
{
    ctx.Response.Headers["X-Content-Type-Options"] = "nosniff";
    ctx.Response.Headers["X-Frame-Options"] = "DENY";
    await next();
});

// CORS for SPA/mobile API
builder.Services.AddCors(options =>
    options.AddPolicy("ShopNestSpa", p => p
        .WithOrigins("https://app.shopnest.com")
        .AllowAnyHeader()
        .AllowCredentials()));

// Rate limiting (.NET 8)
builder.Services.AddRateLimiter(options =>
{
    options.AddFixedWindowLimiter("api", opt =>
    {
        opt.Window = TimeSpan.FromMinutes(1);
        opt.PermitLimit = 100;
    });
});
app.UseRateLimiter();

Certificates: Dev — dotnet dev-certs https --trust. Azure App Service — managed cert free. IIS — bind cert in IIS manager. nginx — reverse proxy with certbot/Let's Encrypt.

Hands-on — ShopNest Production Deployment Security

  1. Enable HTTPS redirect in ShopNest.Web.
  2. CORS policy for local React dev + production SPA origin.
  3. Rate limit /api/auth/login to 10 req/min.
  4. Document Azure App Service HTTPS binding steps.

Common errors & best practices

  • CORS AllowAnyOrigin with AllowCredentials — invalid and insecure.
  • HSTS in Development — breaks local HTTP testing if misconfigured.
  • Expired cert in production — monitor expiry alerts.

Interview questions

Q: HSTS purpose?
A: Tells browser to only use HTTPS for domain — prevents SSL strip attacks.

Q: CORS when needed?
A: Browser blocks cross-origin API calls unless server sends Access-Control-Allow-Origin.

Q: Rate limiting why?
A: Protects login and public API from abuse and DDoS-lite scraping.

Summary

  • HTTPS everywhere — redirect + HSTS in production
  • CORS explicitly whitelists SPA origins
  • Rate limiting protects auth and public endpoints
  • Certificate management differs by host (Azure/IIS/nginx)

Next: Building REST APIs with ASP.NET Core

FAQ

Let's Encrypt on IIS?

Use win-acme or certbot with DNS validation for automated renewal.

IP whitelisting?

Middleware checks RemoteIpAddress against allow list for admin APIs.
