Vulnerability discussion

The cornerstone of PKI is the private key used to encrypt or digitally sign information. The key by itself is a cryptographic value that does not contain specific user information, but the key can be mapped to a user. Without mapping the certificate used to authenticate to the user account, the ability to determine the identity of the individual user or group will not be available for forensic analysis.Messaging servers must provide the capability to utilize and meet requirements of the DoD Enterprise PKI infrastructure for application authentication.Note: Two or more alternative LDAP hosts may be listed, in the CONNAME parameter, separated by commas.Review IBM product documentation for the LDAP fields required when setting up a communication link with the LDAP server.See https://ibm.biz/BdiBGu for a detailed description of these options.

Check content

To access the MQ Appliance CLI, for each queue manager, enter: mqcli To identify the queue managers, enter: dspmq For each queue manager identified, run the command: runmqsc [queue name] DIS AUTHINFO(*) AUTHTYPE(CRLLDAP) CONNAME Verify that an "AUTHINFO" definition of "AUTHTYPE(CRLLDAP)" is displayed and that the CONNAME in parenthesis is the host name or IPv4 dotted decimal address of an organizationally approved LDAP server. If the "AUTHINFO" definition is not equal to "AUTHTYPE(CRLLDAP)", this is a finding.

Fix text

Specify LDAP as the authentication method for each queue manager. To access the MQ Appliance CLI, enter: mqcli runmqsc [queue manager name] DEFINE AUTHINFO('[Object name e.g., USE.CRLLDAP]') AUTHTYPE(CRLLDAP) CONNAME('[LDAPhost1(port)]') REPLACE Type "end" to exit runmqsc mode.

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.
