Security for Replication of Streams

You can configure security measures in these locations:

On clusters
You can replicate between streams that are in secure clusters.
At source streams
The -adminperm parameter in the commands maprcli stream create and maprcli stream edit lets you specify an access-control expression to declare who has administrative permissions on a stream, including permission to replicate the stream.
Across a network
You can send data encrypted or unencrypted when replicating streams by using the -networkencryption parameter when you create or edit a replica.
At gateways
Gateways ensure that replicas receive data only from approved source streams.
