Deploying Monga?

Question

MongoDB

Good afternoon.
Everyone is aware of the mongo vulnerabilities associated with an incomplete initial configuration when it was created.
In this topic, I want to ask how you implement it, what to pay attention to, what not to pay attention to. What initial configurations do you use to secure your base.
Everyone has their own tricks up their sleeves, well, or the basic initial settings "according to the template."
How many pools you expose and other initial settings.
Task: run mongo (centos) on the Yandex test virtual machine, deploy a web application under mongo in the same place on apache.
The database interacts only with the application, and the application with the client. The load is average.
I use the Mongi documentation, but I don't know what to look for.
