The MQ Appliance messaging server must implement NSA-approved cryptography to protect classified information in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards.
An XCCDF Rule
Description
<VulnDiscussion>Cryptography is only as strong as the encryption modules/algorithms employed to encrypt the data. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. NSA has developed Type 1 algorithms for protecting classified information. The Committee on National Security Systems (CNSS) National Information Assurance Glossary (CNSS Instruction No. 4009) defines Type 1 products as: "Cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Developed using established NSA business processes and containing NSA-approved algorithms are used to protect systems requiring the most stringent protection mechanisms." NSA-approved cryptography is required to be used for classified information system processing. The messaging server must utilize NSA-approved encryption modules when protecting classified data. This means using AES and other approved encryption modules.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Devices (endpoints) may connect an MQ Appliance MQ queue manager as either remote MQ queue manager or 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 and/or queue manager).
2. Request a CA-signed certificate for each client and/or queue manager. You might use different CAs for the two endpoints.
3. Add the Certificate Authority certificate to the key repository for each client and/or queue manager. 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.
