To control the security checking performed by MQSeries, you must define switch profiles. A switch profile is a normal security profile that has a special meaning to MQSeries. The access list in switch profiles is not used by MQSeries.
When you set a security switch on, the security checks associated with the switch are performed. When you set a security switch off, the security checks associated with the switch are bypassed. The default is that all security switches are set on.
