Fix Recommendation

A namelist is a MQSeries / WebSphere MQ object that contains a list of queue names. Namelist security validates userids authorized to inquire on namelists. Namelist security will be active, and all profiles ssid.namelist will be defined to the MQNLIST or GMQNLIST class with UACC(NONE) specified. Restrict read access to those userids requiring access to make namelist inquiries.

For all namelist resources (i.e., ssid.namelist) defined to the MQNLIST or GMQNLIST resource classes, ensure the following items are in effect:

NOTE 1: ssid is the queue manager name (a.k.a., subsystem identifier).

1) Resource profiles are defined with a UACC(NONE).
2) Access authorization restricts access to users requiring the ability to make namelist inquires. This is difficult to determine. However, an item for concern may be a profile with * READ specified in the access list.

A set of sample commands are provided below to implement the minimum profiles necessary for proper security.

/* THE FOLLOWING PROFILE FORCES GRANULAR PROFILES DEFINITIONS */
RDEF MQNLIST ** UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) DATA('MQCONN DENY-BY-DEFAULT PROFILE')

RDEF MQNLIST <ssid>.** UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) DATA('REQUIRED FOR ZWMQ0056')
PE <ssid>.** CL(MQNLIST) ID(<applicable>)

SETR RACL(MQNLIST) REF

Note that an additional WebSphere MQ Refresh may be required for active Qmanagers. This is done from the CONSOLE:

The example is for a Que Manager Named QMD1

Check Contents

a) Refer to the following reports produced by the RACF Data Collection:

- SENSITVE.RPT(MQNLIST)

b) For all namelist resources (i.e., ssid.namelist) defined to the MQNLIST or GMQNLIST resource classes, ensure the following items are in effect:

NOTE 1: ssid is the queue manager name (a.k.a., subsystem identifier).

1) Resource profiles are defined with a UACC(NONE).
2) Access authorization restricts access to users requiring the ability to make namelist inquires. This is difficult to determine. However, an item for concern may be a profile with * READ specified in the access list.

c) If both of the items in (b) are true, there is NO FINDING.

d) If either item in (b) is untrue, this is a FINDING.
