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.
