Course 1

Implementing Rate Limiting in ASP.NET Core

4 lessons

13 practices

Learn to secure your ASP.NET Core REST API by implementing rate limiting strategies to control request volume and protect your Pastebin backend from abuse. Rate limiting provides a critical line of defense against both accidental overloads and intentional attacks, keeping your application responsive and stable for legitimate users.

Course 2

Throttling API Requests

4 lessons

13 practices

Throttling manages high request volumes by controlling how requests are processed when thresholds are exceeded. Unlike rate limiting, which rejects excess requests outright, throttling uses strategies like delays, token buckets, and queues to manage traffic flow. This keeps your API responsive and stable during traffic spikes.

Course 3

Mastering CORS in ASP.NET Core

4 lessons

10 practices

Modern web apps often need to fetch resources from different domains. CORS defines how servers declare which origins can make requests. By default, browsers block cross-origin requests, so you’ll configure your ASP.NET Core backend to respond with the necessary headers.

Course 4

Preventing Refresh Token Abuse

4 lessons

15 practices

Modern web applications frequently rely on refresh tokens to seamlessly re-authenticate users without forcing them to log in repeatedly. While convenient, mishandling refresh tokens can grant attackers near-permanent access.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
