API security governance can address several API security issues, including:
Authentication and Authorization: Ensuring that only legitimate users and applications can access the API. For example, implementing OAuth 2.0 for granting permissions to third-party applications.
Data Validation and Sanitization: Preventing injection attacks by validating and sanitizing all input data to ensure it meets expected formats and types.
Rate Limiting: Protecting the API from abuse by limiting the number of requests a client can make within a specified time frame, which helps mitigate denial-of-service (DoS) attacks.
API Key Management: Securely managing and distributing API keys to control access and usage, ensuring that each key is associated with specific permissions.
Encryption: Ensuring data in transit is secure by using HTTPS/TLS encryption, protecting sensitive information from interception.
Audit Logging: Keeping detailed logs of API usage, which can help in identifying and investigating security incidents or misuse.
Compliance: Ensuring that the API adheres to relevant data protection regulations (like GDPR or HIPAA), which is crucial for legal compliance and protecting user data.
For instance, in the context of cloud services, Tencent Cloud offers services like Tencent Cloud API Gateway which provides comprehensive API management features including authentication, authorization, rate limiting, and encryption, helping to secure APIs effectively.
