1.5.4 Ensure that the --peer-cert-file and --peer-key-file arguments are set as appropriate - peer-key-file

Information

etcd should be configured to make use of TLS encryption for peer connections.

Rationale:

etcd is a highly-available key value store used by Kubernetes deployments for persistent storage of all of its REST API objects. These objects are sensitive in nature and should be encrypted in transit and also amongst peers in the etcd clusters.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Follow the etcd service documentation and configure peer TLS encryption as appropriate for your etcd cluster.

Impact:

etcd cluster peers would need to set up TLS for their communication.
