The MQ Appliance messaging server must ensure authentication of both SSH client and server during the entire session.
An XCCDF Rule
Description
<VulnDiscussion>This control focuses on communications protection at the session, versus packet level. At the application layer, session IDs are tokens generated by web applications to uniquely identify an application user's session. Web applications utilize session tokens or session IDs in order to establish application user identity. Proper use of session IDs addresses man-in-the-middle attacks, including session hijacking or insertion of false information into a session. Messaging servers must provide the capability to perform mutual authentication. Mutual authentication is when both the client and the server authenticate each other.

Remediation - Manual Procedure
The most common way devices (endpoints) may connect an MQ Appliance MQ queue manager is as an MQ client. In order to ensure unique identification of network-connected devices, mutual authentication using CA-signed TLS certificates should be configured.
1. Prepare the key repository on each endpoint client.
2. Request a CA-signed certificate for each client. You might use different CAs for the two endpoints.
3. Add the Certificate Authority certificate to the key repository for each client. If the endpoints are using different Certificate Authorities then the CA certificate for each Certificate Authority must be added to both key repositories.
4. Add the CA-signed certificate to the key repository for each endpoint.
