rate limiting and replay protection +- **Memory Usage**: Each request creates temporary Redis keys with TTL +- **Network Latency**: Consider Redis network latency for high-throughput scenarios + +### Rate Limiting Performance +- **Sliding Window**: More accurate but requires more Redis operations +- **Token Bucket**: Efficient and fair resource allocation +- **Fallback**: In-memory rate limiting when Redis is unavailable + +### Audit Logging Performance +- **Async Operations**: Audit logging is performed asynchronously to minimize impact +- **Payload Truncation**: Configure truncation to reduce log size +- **TTL Management**: Audit logs automatically expire after 30 days + +## Security Considerations + +### Sensitive Data +- **No Plaintext Secrets**: API keys and secrets are never logged in plaintext +- **Payload Truncation**: Request payloads are truncated in logs +- **JWT Secret**: Store JWT secret securely (environment variables, secret management) + +### Replay Protection +- **Request ID Uniqueness**: Ensure request IDs are sufficiently unique +- **Time Window**: Configure appropriate replay protection windows +- **Redis Persistence**: Ensure Redis persistence for replay protection + +### Rate Limiting Bypass +- **IP Spoofing**: Rate limiting by IP can be bypassed with IP spoofing +- **Token Sharing**: Per-token rate limits can be bypassed by sharing tokens +- **Distributed Attacks**: Consider additional protection for distributed attacks + +## Monitoring and Debugging + +### Health Checks +Monitor the following metrics: +- Authentication success/failure rates +- Rate limit hit rates +- Request validation error rates +- Audit log volume + +### Debug Logging +Enable debug mode for detailed logging: +```bash +GIN_MODE=debug
