Vulnerability discussion

Preventing the disclosure or modification of transmitted information requires that messaging servers take measures to employ approved cryptography in order to protect the information during transmission over the network. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPsec tunnel.If data in transit is unencrypted, it is vulnerable to disclosure and modification. If approved cryptographic algorithms are not used, encryption strength cannot be assured.FIPS 140-2 approved TLS versions include TLS V1.0 or greater.TLS must be enabled and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 specifies the preferred configurations for government systems.To achieve FIPS 140-2 compliance on Windows, UNIX, and Linux systems, all key repositories have been created and manipulated using only FIPS-compliant software, such as runmqakm with the -fips option.

Check content

To access the MQ Appliance CLI, enter: mqcli To identify the queue managers, enter: dspmq For each queue manager identified, run the command: runmqsc [queue name] DIS QMGR SSLFIPS If the value of "SSLFIPS" is set to "NO", this is a finding.

Fix text

To access the MQ Appliance CLI, for each queue manager, enter: mqcli runmqsc [queue manager name] ALTER QMGR SSLFIPS(YES) end

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.
