Enabling IP Security for MongoDB 3.6 on Ubuntu` is a tutorial that guides users through the process of configuring their MongoDB server to listen on specific network interfaces beyond localhost. The goal is to ensure data security by denying unauthorized access from public networks and allowing only private network connections and localhost. The tutorial assumes users have installed MongoDB 3.6, multiple network interfaces on their server, and a basic understanding of IP Networks. By editing the `/etc/mongodb.conf` file, users can bind the local IP address associated with their private network to the MongoDB instance, enabling it to listen from both that IP and localhost. This configuration ensures secure connections and protects against remote intrusion.
