WebSphere MQ Channel security can be configured to provide authentication, message privacy, and message integrity between queue managers. Secure Sockets Layer (SSL) uses encryption techniques, digital signatures and digital certificates to provide message privacy, message integrity and mutual authentication between clients and servers. Failure to properly secure a WebSphere MQ channel may lead to unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of some system services, applications, and customer data. Satisfies: SRG-OS-000505, SRG-OS-000555

IBM WebSphere MQ can use a user ID associated with an ACP certificate as a channel user ID. When an entity at one end of an SSL channel receives a certificate from a remote connection, the entity asks The ACP if there is a user ID associated with that certificate. The entity uses that user ID as the channel user ID. If there is no user ID associated with the certificate, the entity uses the user ID under which the channel initiator is running. Without a validly defined Certificate Name Filter for the entity IBM WebSphere MQ will set the channel user ID to the default.
Checks: C-26236r868582_chk

Validate that the list of all Production WebSphere MQ Remotes exist, and contains approved Certified Name Filters and associated USERIDS. If the filter(s) is (are) defined, accurate and has been approved by Vulnerability ICER0030 and the associated USERID(s) is only granted need to know permissions and authority to resources and commands, this is not a finding. If there is no Certificate Name Filter for WebSphere MQ Remotes this is a Finding. Note: Improper use of CNF filters for MQ Series will result in the following Message ID. CSQX632I found in the following example: CSQX632I csect-name SSL certificate has no associated user ID, remote channel channel-name - channel initiator user ID used

Fix: F-26224r868583_fix

The responsible MQ System programmer(s) shall create and maintain a spread sheet that contains a list of all Production WebSphere MQ Remotes, associated individual USERIDs with corresponding valid Certified Name Filters (CNF). This documentation will be reviewed and validated annually by responsible MQ System programmer(s) and forwarded for approval by the ISSM. The ISSO will define the associated USERIDs, the CNF, and grant the minimal need to know access, by granting only the required resources and Commands for each USERID in the ACP. See IBM WebSphere MQ Security manual for details on defining CNF for WebSphere MQ. Generic access shall not be granted such as resource permission at the SSID. MQ resource level.

Switch profiles are special MQSeries/WebSphere MQ profiles that are used to turn on/off security checking for a type of resource. Due to the security exposure this creates, no profiles with the first two qualifiers of ssid.NO will be defined to the MQADMIN class, with one exception. Due to the fact that (1) all sensitive MQSeries/WebSphere MQ commands are restricted to queue managers, channel initiators, and designated systems personnel, and (2) no command resource checking is performed on DISPLAY commands, at the discretion of the IAO a ssid.NO.CMD.RESC.CHECKS switch profile may be defined to the MQADMIN class. 1. Identify if any switch profiles exist using the sample search command: SR CLASS(MQADMIN) NOMASK FILTER(*.NO.**) 2. Use the "RDEL MQADMIN <SwitchProfileName>" to remove the profile and follow up with a "SETR RACL(MQADMIN) REF" 3. An additional refresh to an active WebSphere MQ Que Manager may be required.

a) Refer to the following report produced by the z/OS Data Collection: - MQSRPT(ssid) NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). b) Review the ssid report(s) and perform the following steps: 1) Find the DISPLAY QMGR DEADQ command to locate the start of the dead-letter queue information. Review the DEADQ parameter to obtain the name of the real dead-letter queue. 2) From the top of the report, find the QUEUE(dead-letter.queue.name) entry to locate the start of the real dead-letter queue definition. Review the GET and PUT parameters to determine their values, and ensure they conform to the specified security requirements. The standard values are: GET(ENABLED) PUT(ENABLED) NOTE: Dead-letter.queue.name is the value of the DEADQ parameter determined in Step 1. 3) From the top of the report, find the QUEUE(dead-letter.queue.name.PUT) entry to locate the start of the alias dead-letter queue definition. Review the GET and PUT parameters to determine their values, and ensure they conform to those specified in the security requirements. The standard values are: GET(DISABLED) PUT(ENABLED) NOTE 1: Dead-letter.queue.name is the value of the DEADQ parameter determined in Step 1. NOTE 2: The TARGQ parameter value for the alias queue will be the real dead letter queue name. NOTE 3: If an alias queue is not used in place of the dead-letter queue, then the ACP rules for the dead-letter queue must be coded to restrict unauthorized users and systems from reading the messages on the file. c) If all of the items in (b) are true, there is no finding. d) If any item in (b) is untrue, this is a finding.

The systems programmer responsible for supporting MQSeries/WebSphere MQ will ensure that the dead-letter queue and its alias are properly defined. The following scenario describes how to securely define a dead-letter queue: (1) Define the real dead-letter queue with attributes PUT(ENABLED) and GET(ENABLED). (2) Give update authority for the dead-letter queue to CKTI (the MQSeries/WebSphere MQ-supplied CICS task initiator), channel initiators, and any automated application used for dead-letter queue maintenance. (3) Define an alias queue that resolves to the real dead-letter queue, but give the alias queue the attributes PUT(ENABLED) and GET(DISABLED). (4) To put a message on the dead-letter queue, an application uses the alias queue. The application does the following: (a) Retrieve the name of the real dead-letter queue. To do this, it opens the queue manager object using MQOPEN, and then issues an MQINQ to get the dead-letter queue name. (b) Build the name of the alias queue by appending the characters ".PUT" to this name, in this case, ssid.DEAD.QUEUE.PUT. (c) Open the alias queue, ssid.DEAD.QUEUE.PUT. (d) Put the message on the real dead-letter queue by issuing an MQPUT against the alias queue. (5) Give the userid associated with the application update authority to the alias, but no access to the real dead-letter queue. NOTE: If an alias queue is not used in place of the dead-letter queue, then the ACP rules for the dead-letter queue will be coded to restrict unauthorized users and systems from reading the messages on the file. Undeliverable messages can be routed to a dead-letter queue. Two levels of access should be established for these queues. The first level allows applications, as well as some MQSeries/WebSphere MQ objects, to put messages to this queue. The second level restricts the ability to get messages from this queue and protects sensitive data. This will be accomplished by defining an alias queue that resolves to the real dead-letter queue, but defines the alias queue with the attributes PUT(ENABLED) and GET(DISABLED). The ability to get messages from the dead-letter queue will be restricted to message channel agents (MCAs), CKTI (MQSeries/WebSphere MQ-supplied CICS task initiator), channel initiators utility, and any automated application used for dead-letter queue maintenance.
