API Security for Mobile Apps
1. Introduction
API security is critical in mobile app development, as APIs are the backbone of mobile applications, facilitating communication between the app and backend services.
2. Key Concepts
2.1 What is an API?
API stands for Application Programming Interface, which allows different software applications to communicate with each other.
2.2 Importance of API Security
Securing APIs prevents unauthorized access, keeps user data safe, and ensures the integrity and availability of your application.
2.3 Authentication and Authorization
- Authentication verifies the identity of a user or application.
- Authorization determines what authenticated users can do.
3. Best Practices for API Security
3.1 Use HTTPS
Always use HTTPS to encrypt data in transit.
3.2 Implement Authentication
Use OAuth 2.0 or JWT for secure authentication.
3.3 Validate Inputs
Always validate inputs to prevent injection attacks.
3.4 Rate Limiting
Implement rate limiting to prevent abuse and DDoS attacks.
3.5 Monitor and Log
Continuously monitor and log API requests for anomalies.
4. Common Vulnerabilities
4.1 SQL Injection
Attackers can manipulate SQL queries by injecting malicious input.
4.2 Cross-Site Scripting (XSS)
XSS allows attackers to inject scripts into web pages viewed by other users.
4.3 Insecure Direct Object References
Attackers can access unauthorized resources by manipulating URLs.
5. FAQ
What is the difference between authentication and authorization?
Authentication verifies user identity, while authorization determines user access levels.
How can I secure my API endpoints?
Implement HTTPS, use strong authentication methods, validate inputs, and log activities.
