Fix Recommendation

Switch profiles are special 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 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 profile permissions exist using the sample TSS command: TSS WHOHAS MQADMIN(ssid.NO) 2. Use the "TSS REVOKE(acid) MQADMIN(ssid.NO)" to revoke the permission.
