Have a look at this doc http://spark.apache.org/docs/latest/security.html

You can configure your network to only accept connections from the trusted CIDR. If you are using Cloud services like Ec2/Azure/GCE etc, then it is straight forward from their web portal. If you are having a bunch of custom vps's then you might want to configure the iptable entries.
