In-transit encryption (TLS) in MemoryDB

Focus mode
In-transit encryption (TLS) in MemoryDB - Amazon MemoryDB

To help keep your data secure, MemoryDB and Amazon EC2 provide mechanisms to guard against unauthorized access of your data on the server. By providing in-transit encryption capability, MemoryDB gives you a tool you can use to help protect your data when it is moving from one location to another. For example, you might move data from a primary node to a read replica node within a cluster, or between your cluster and your application.

In-transit encryption overview

MemoryDB in-transit encryption is a feature that increases the security of your data at its most vulnerable points—when it is in transit from one location to another.

MemoryDB in-transit encryption implements the following features:

  • Encrypted connections—both the server and client connections are Transport Layer Security (TLS) encrypted.

  • Encrypted replication—data moving between a primary node and replica nodes is encrypted.

  • Server authentication—clients can authenticate that they are connecting to the right server.

From 07/20/2023, TLS 1.2 is the minimum supported version for new and existing clusters. Use this link to learn more about TLS 1.2 at AWS.
