SV-89523r1_rule The MQ Appliance messaging server must use encryption strength in accordance with the categorization of the management data during remote access management sessions.

Vulnerability discussion

Remote management access is accomplished by leveraging common communication protocols and establishing a remote connection to the messaging server via a network for the purposes of managing the messaging server. If cryptography is not used, then the session data traversing the remote connection could be intercepted and compromised. Types of management interfaces utilized by a messaging server include web-based HTTPS interfaces as well as command line-based management interfaces.

Check content

To access the MQ Appliance CLI, enter: mqcli config crypto show crypto-mode If the current setting is set to "permissive", this is a finding.

Fix text

To set management access to the highest encryption strength, enable FIPS 140-2 Level 1 mode at the next reload of the firmware. Enter the following commands: config crypto crypto-mode-set fips-140-2-l1 Press "Enter" The following message will appear: "Crypto Mode Successfully set to fips-140-2-l1 for next boot."

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
