Node-to-Node Encryption with Couchbase Server 6.5

Couchbase Server 6.5 introduces a highly anticipated node-to-node encryption feature, enhancing security by encrypting data exchanged between nodes in a distributed data platform. Previously, encryption was limited to client-server interactions and XDCR traffic between data centers, leaving node communication vulnerable in the absence of complex network-wide security controls. With this new feature, Couchbase natively encrypts both control and user data traffic between nodes, offering flexibility in encryption levels to balance security and performance. While node-to-node encryption strengthens security, it complements existing measures such as client-server encryption and network-level isolation. Setting up this feature involves straightforward steps during the installation or upgrade of Couchbase Server, and regular certificate rotation is recommended for maintaining secure operations.
