How API Gateways Improve Security
API Gateways serve as a secure entry point for your applications. They control and monitor all traffic between users and backend services, helping you protect sensitive data and systems from unauthorized access and threats. By centralizing security measures, API Gateways make it easier to enforce authentication, authorization, and traffic management policies across your APIs.
How API Gateways Enhance Security
API gateways act as security guards for your backend services. They handle several important security tasks:
Authentication
Authentication means verifying who you are. When you send a request, the API gateway checks your credentials, such as a username and password or an API key. If your credentials are valid, the gateway lets your request through. If not, it blocks you. For example, when you log in to a shopping app, the API gateway checks your login details before allowing access to your account.
Authorization
Authorization controls what you are allowed to do. After confirming your identity, the API gateway checks if you have permission to access specific resources. For example, a regular user might only see their own orders, while an admin can see all orders. The gateway enforces these rules, so users only do what they are allowed.
Request Filtering
Request filtering blocks harmful or unwanted requests. The API gateway can detect and stop requests that look suspicious, such as those containing malicious code or coming from banned locations. For instance, if someone tries to send a request with a dangerous script, the gateway rejects it to protect your system.
Traffic Monitoring
Traffic monitoring means keeping an eye on the data flow. The API gateway records details about who is sending requests, when, and what they are asking for. If it notices unusual activity, like too many requests from the same user in a short time, it can alert you or temporarily block the user. This helps prevent attacks and ensures your services run smoothly.
By handling authentication, authorization, request filtering, and traffic monitoring, API gateways provide a strong first line of defense for your applications.
