How can I turn off monitoring of internal suspicious communications

Hello I am getting messages of my firewall of suspicious behaviours.
By example if I past from one application to a other

I have read the manual Allow or Block Internet Access to Applications Selectively

But I do not know how I can setup the monitoring of internal communications
Can some point me to the manual to block/allow a application.

Are you referring to D+ alerts where it will report that program A is trying to start program B?

yes

You will get that type of alert when one or both programs are not known to CIS. If you know and trust both programs it is easiest to add them to the Trusted Files list. The easiest way is add is to select the program(s) from the running processes list.
