MQ Appliance messaging servers must use NIST-approved or NSA-approved key management technology and processes.
An XCCDF Rule
Description
<VulnDiscussion>An asymmetric encryption key must be protected during transmission. The public portion of an asymmetric key pair can be freely distributed without fear of compromise, and the private portion of the key must be protected. The messaging server will provide software libraries that applications can programmatically utilize to encrypt and decrypt information. These messaging server libraries must use NIST-approved or NSA-approved key management technology and processes when producing, controlling, or distributing symmetric and asymmetric keys. 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.

Remediation - Manual Procedure
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.
On the MQ Appliance queue manager, define a server-connection channel by issuing a command as in the following example:
