MongoDB features several mechanisms that allow you to authenticate users, with the default mechanism being its Salted Challenge Response Authentication Mechanism (SCRAM). Authorization, on the other hand, involves setting rules for a given user or group of users to define what actions they can perform and which resources they can access.

Authentication is the process of confirming whether a user or client is actually who they claim to be. These two concepts are similar, but it’s important to understand what they are and what makes them different.

How To Configure Remote Access for MongoDB on Ubuntu 20.04Īuthorization and authentication are two concepts that are critical for understanding database security.

What is a Firewall and How Does It Work?.

In such cases, you can additionally bind your instance to an IP address or hostname where the remote computer can reach the database server. However, this setting will cause problems if you need to access the database remotely from another machine. This default setting is secure, since it means the database is only accessible to those who already have access to the server on which it’s installed. This means that, without further configuration, a fresh Mongo installation will only be able to accept connections that originate from localhost, or the same server on which the MongoDB instance is installed. By default, MongoDB is bound only to localhost upon installation. For example, you could write rules that would only allow an application server access to the port on your database server used by a MongoDB installation.Īnother way to limit your database’s network exposure is to configure IP binding. Firewall tools generally allow you to define rules with a high level of precision, giving you the flexibility to grant connections from specific IP addresses access to specific ports on your server.

You could have more granular control over who has access to your data by setting up a firewall on your database server.Ī firewall provides network security by filtering incoming and outgoing traffic based on a set of user-defined rules. For instance, there may be a large number of people who need access to your VPN but only a few of them need access to your Mongo database. On its own, though, a VPN may not be enough to prevent unauthorized users from accessing your MongoDB installation. By running MongoDB behind a VPN, you can block access to any machine that isn’t connected to the same VPN. A VPN presents its connection as if it were a local private network, allowing for secure communications between the servers within it. One way to do this is to provision a virtual private network (VPN). The most fundamental way you can protect the data you store in MongoDB is to limit network access to the server on which the database is running. View the SQL Mapping reference to see how the MongoSQL syntax and commands map to MongoDB's commands.Īll MongoSQL queries are SELECT statements of this form: SELECT expr1 alias1], expr2 alias2]. The MongoSQL Query Syntax is designed to allow the use of SQL-like statements to query the structured data documents of MongoDB. When specifying collection_name, if the collection is in a different database than the current database, you can use the syntax db.collection_name. In this document, keywords such as SELECT are capitalized for illustration purposes. See the SQL Mapping page for how Aqua Data Studio's syntax maps to MongoDB Query syntax ( ). This document details Aqua Data Studio's MongoSQL syntax and functions. MongoSQL queries are written using a subset of the SQL-92 standard.
