API Security: Protecting Endpoints and Data APIs connect apps, devices, and users. A single weak endpoint can expose data or allow misuse. Security should be built into the API design: check who can call, what they can do, and how data moves. A simple rule helps: assume threats and block them with clear controls. Protecting Endpoints Securing endpoints means controlling access at every entry point. Use a central authentication system and enforce authorization on each request. Validate input to block common attacks and apply rate limits to slow abuse. A gateway or service mesh can apply these rules consistently across many services. ...

Building Secure APIs: Design, Auth, and Rate Limiting APIs power many apps today. To serve users well, you need to design APIs that are easy to use and hard to abuse. A secure API protects data, respects privacy, and stays reliable as traffic grows. Authentication Choose a solid method. OAuth 2.0 with PKCE is a good fit for mobile and single-page apps. For server-to-server calls, consider mutual TLS (mTLS) or client credentials with a trusted backend. Use short lived access tokens, rotate them, and validate on every request. Check the token audience and issuer, and reject tokens that fail these checks. ...

API Gateway Design and Security An API gateway sits at the edge of a system, guiding traffic, enforcing policy, and shaping security. It handles authentication, routing, rate limits, and observability. A well designed gateway reduces load on back-end services, improves reliability, and makes it easier to update security rules without touching every service. Design goals Centralized access control Consistent policy enforcement Fast, reliable traffic with low latency Clear observability and traceability Simple developer onboarding and policy changes A gateway should act as a single source of truth for how clients access APIs. It also helps teams rotate security controls without large rewrites, which saves time during incidents or audits. ...

Secure API Design: Authentication, Authorization, and Rate Limiting APIs are the bridge between services and users. A secure design helps protect data, keep services reliable, and prevent abuse. This article explains three core parts: authentication, which proves who you are; authorization, which controls what you can do; and rate limiting, which guards against overload. Authentication Choose a strong method to verify identity. Common options: API keys for simple use, but tie them to limits and rotate them periodically. OAuth 2.0 for robust access with tokens and scopes. JWTs for stateless tokens that carry claims, with careful signing and expiration. Mutual TLS for high security between services. Practical tips: ...

Building Secure Web Apps: OAuth, JWT, and Beyond Secure web apps hinge on clear identity and careful token use. OAuth 2.0 lets apps access user data without passwords, while OpenID Connect adds login. JWTs carry information in a compact token, but they must be validated and kept short-lived. In practice, combine OAuth with OpenID Connect for sign-in and use PKCE for public clients like mobile apps or browser SPAs. Treat access tokens as keys to APIs. Protect them in transit with TLS and store them securely; httpOnly cookies are a safe default for web apps. Request only the permissions you need with scopes. ...

Secure API Design: Tokens, Roles, and Scopes APIs stay secure when they rely on tokens rather than user names. A token proves who is calling the API and what they are allowed to do. Roles group users or services by duty, while scopes limit each call to a specific action or resource. Tokens are issued by an authorization server after proper checks. Each API request carries the token, and the API validates it, checks its issuer (iss), audience (aud), and expiration (exp). The endpoint then confirms required scopes and, where needed, a user or service role. ...
