Nacos instances support Transport Layer Security (TLS) encryption for data in transit and fine-grained access control for client authentication, registries, and configuration centers.
TLS for data security
The Nacos engine supports TLS to ensure the security of transmitted data. For more information, see Enable TLS for MSE Nacos instances.
Permission management
You can manage access permissions for Nacos instances by configuring Nacos client authentication, fine-grained authentication in registries, and fine-grained authentication in configuration centers. For more information, see Nacos permission management.
