We are finding/seeing more and more unsecured mongo instances in AWS and in private datacenters.

Since we recommend using the server without auth, a lot of these databases are completely open to the public #scary

As a result, this is causing problems with MMS.

We are taking steps to work around this problem in MMS, but it is probably a good idea to write an article/post/wiki page about how to do this.

It seems inane, but people are operating their databases with unsecured environments.

Setting up a security group in AWS
Configuring iptables on a linux node
Whatever firewall windows has
Possible - some common 3rd party firewalls
