Security in RESTful APIs: Good practices guide
Protect your data and that of your users by shielding the gateway between your applications and servers.
In FenixDevApp, privacy and security are fundamental. A polished mobile or web frontend is of no use if the server exposes vulnerable information due to an insecure or misconfigured API.
1. Strong Authentication with JWT
Implements secure JSON Web Tokens (JWT) using robust signing algorithms such as RS256. Store credentials with advanced cryptographic hashes (such as bcrypt or Argon2) and set short expiration times for access tokens.
2. HTTPS Mandatory and CORS strict
Encrypts all traffic using TLS/HTTPS. Configure CORS headers restrictively on the backend server to allow requests only from trusted authorized domains, preventing cross-origin attacks.
3. Implement Rate Limiting and Validation
Protect your backend from denial of service (DDoS) and brute force attacks by limiting the number of requests that the same user or IP address can make per minute. Also, never trust customer data: validate and sanitize every parameter received.
Security by Design
Considering security as a fundamental part of the architecture and not as a last-minute addition guarantees the protection of your business's most valuable asset: your users' information.
