API Security
Practices and technologies for protecting APIs from threats including unauthorized access, data breaches, and abuse.
In-Depth Explanation
API security encompasses the practices, technologies, and policies for protecting APIs from threats. As APIs expose critical functionality and data, they are prime targets for attackers.
Security concerns:
- Authentication: Verifying identity
- Authorization: Verifying permissions
- Data protection: Encryption, privacy
- Rate limiting: Preventing abuse
- Input validation: Preventing injection
- Logging/monitoring: Detecting attacks
Authentication methods:
- API keys (simple but limited)
- OAuth 2.0 (industry standard)
- JWT tokens (stateless auth)
- mTLS (mutual TLS certificates)

Business Context
API security is critical for US businesses as APIs expose sensitive data. Breaches can result in data theft, financial loss, and regulatory penalties under CCPA, HIPAA, SOX, and state privacy laws.
