Data-in-transit encryption

ElastiCache ensures the encryption of data when in transit from one location to another. ElastiCache in-transit encryption implements the following features:

  • Encrypted connections: In this mode, SSL-based encryption is enabled for server and client communication
  • Encrypted replication: Any data moving between the primary node and the replication node are encrypted
  • Server authentication: Using data-in-transit encryption, the client checks the authenticity of a connection—whether it is connected to the right server
  • Client authentication: After using data-in-transit encryption, the server can check the authenticity of the client using the Redis authentication feature
