Using message protection

To use message protection (sometimes known as Quality of Protection (QoP)), set the enableQopSecurity parameter of the mqsichangeproperties command to true. The default value of this parameter is false.

To define a level of message protection for $SYS topics, use the sysQopLevel parameter of the mqsichangeproperties command.

To define a level of message protection for $ISYS topics, use the isysQopLevel parameter of the mqsichangeproperties command.

Choose one of the following values for these parameters:
n
This is the default value. It gives no message protection.
c
This provides channel integrity. With this level of protection, hackers cannot insert or delete messages without being detected.
m
This provides message integrity. With this level of protection, hackers cannot change the content of a message without being detected.
e
This provides message encryption. With this level of protection, hackers cannot look at the content of a message.
