The OWASP API Security Top 10 is a list of the most significant threats to APIs, which are critical components of modern applications that can leak sensitive data and expose organizations to various attacks. To address these risks, the document provides best practices for enhancing security posture and reducing the attack surface of APIs. The top 10 risks include Broken Object Level Authorization, Broken User Authentication, Excessive Data Exposure, Lack of Resources & Rate Limiting, Broken Function Level Authorization, Mass Assignment, Security Misconfiguration, Injection, Improper Assets Management, and Insufficient Logging & Monitoring. These risks can be mitigated by implementing measures such as proper authorization systems, secure authentication techniques, data filtering, rate limiting, function-level authorizations, schema validation, hardening configurations, least privilege principle, input validation, secure APIs, inventorying assets, monitoring infrastructure, and logging activities. The document aims to empower developers with free materials and frameworks to create safe web applications and APIs.
