RPA Communication Security Level

I was recently installing RecoverPoint and I ran across something that I have never seen before.  During the Deployment Manager setup step 13 is “RPA Communication Security Level”.

RP Security WAN

RecoverPoint 4.1.1 now supports Message Passing Interface (MPI) security for communication between RPA clusters. RecoverPoint MPI security offers the following RPA communication security levels:

Accessible – Communication between RPA clusters is not authenticated or encrypted. However, RPA clusters can communicate with each other only by adhering to the RecoverPoint proprietary protocol.

Authenticated – RPA clusters use certificates to authenticate each other before communicating. This option minimally impacts RPA performance.

Authenticated and Encrypted – RPA clusters use certificates to authenticate each other before communicating. All communication between RPA clusters is also encrypted.
