I was wondering if anyone knew of an effective method of enforcing authentication against an approved list in Spark.
Currently, as I understand it, if I setup Spark on a device in my internal network that has access to my file server then that device can login to any Spark account at all. This would allow anyone to get round any sort of DLP policies I might have in place as well as providing a very neat way of bringing malware into the environment over an encrypted tunnel.
Is there a way that I can enforce authentication from the Spark app to only allow login to a certain list of accounts? Whether this is via integration with a local Active Directory server, or some option that integrates a locked down configuration in the local app and a configuration in the Spark Control Hub.
