Introduction
Securing Web APIs is a crucial part of modern application development since every API can be a potential target. With .NET 8, Microsoft provides built-in tools that make it easier to protect APIs from unauthorized access. Features like JWT authentication, role-based authorization, and CORS help enforce strong security within applications.
These protections can be strengthened further with HTTPS, rate limiting, and token validation to guard against common threats. Combined, they create a solid security strategy that balances safety with performance. In this article, we’ll look at practical ways to secure a Web API in .NET 8 with code examples.
