# Qt GRPC Security Considerations

If you are using Qt GRPC, consider security aspects to protect users, network traffic, and hardware from threats.

Here are some strategies to consider:

- Use encryption when sending or receiving data. Encrypted data adds protection against eavesdropping and similar attacks. Qt Network provides support for TLS encryption which can use different TLS backends and ciphers. For more information, see Secure Sockets Layer (SSL) Classes.
- Use strong authentication and authorization mechanisms. To accommodate different users on different platforms, you may choose to use several OAuth2 and OpenID-based services. Qt offers support for these APIs through the Qt Network Authorization module.
- Validate and process untrusted data safely. Input fields and other incoming data are vulnerable to injection attacks. For more information, see Handling Untrusted Data.
- Set rate limits and monitor traffic to prevent misuse. Qt GRPC can be vulnerable to denial-of-service attacks and setting limits and thorough testing can help with reducing the risk of traffic overload.
- Update your environment to fix security vulnerabilities. System hardware should be updated to use the latest security features and fixes.
