Fix Recommendation

RESLEVEL security profiles control the number of userids checked for API resource security. RESLEVEL security will not be implemented due to the following exposures and limitations:

(1) RESLEVEL is a powerful option that can cause the bypassing of all security checks.

(2) Security audit records are not created when the RESLEVEL profile is utilized.

(3) If the WARNING option is specified on a RESLEVEL profile, no warning messages are produced.

In order to protect against any profile in the MQADMIN class, such as ssid.**, resolving to a RESLEVEL profile, an ssid.RESLEVEL permission will be created for each queue manager with an access of none.

The following sample command prevents access to ssid.RESLEVEL:

TSS PER(ALL) MQADMIN(ssid.RESLEVEL) ACCESS(NONE)
