API Common Security Threats and Security Protection Strategies

This study analyzes the core role of APIs in modern digital ecology and the security threats they face, such as information leakage and overstepping access, and explores their security risks for technologies such as RESTful and GraphQL. It proposes to use OAuth/JWT authentication mechanism to strengthen access control, adopt HTTPS/TLS to secure data transmission, and combine with API gateway to defend against DDoS attacks. It also emphasizes the importance of fine-grained privilege management and log auditing. The study provides strategic guidance for improving API security protection and looks forward to the trend of intelligent protection.
