Execution Order

Execution order in plugin specifies the order, also known as rank, that plug-ins are executed within a pipeline stage Plug-ins registered with an order value of 1 are executed first, followed by plug-ins registered with an order of 2, and so on. However, if there is more than one plug-in in a stage with the same order value, then the plug-in with the earliest compilation date is called first.

Unsecure Configuration

Unsecure configuration information could be read by any user in CRM. Remember its public information (Eg: Parameter strings to be used in plugin could be supplied here)

Imagine that you include a plugin, plugin steps and activate them in a solution. Later solution was exported as Managed Solution to another environment. In this scenario, the supplied Unsecure configuration values would be available in the new environment

Secure Configuration

The Secure Configuration information could be read only by CRM Administrators.(Eg: Restricted data from normal user could be supplied here)

Imagine that you include a plugin,plugin steps and activate them in asolution. Later solution was exported as Managed Solution to another environment. In this scenario, the supplied Secure configuration  information wouldNOT be available in the new environment. The simple  reason behind this is to provide more security to the contents of Secure Configuration.
