Simple ways to secure MongoDB

MongoDB is a popular open-source, document-oriented database management system for modern applications. It was developed by MongoDB Inc. and is used by many large organizations and startups worldwide. This article will explore MongoDB in-depth, comparing it to other databases, its use cases, features, advantages, disadvantages, and more.


What is MongoDB?

MongoDB is a NoSQL database that stores data in flexible, JSON-like documents. This allows developers to work with data in a way similar to how they work with objects in their code. MongoDB is known for its scalability, performance, and flexibility, making it a popular choice for modern web applications.

Unlike traditional relational databases, MongoDB does not use tables, rows, and columns. Instead, data is stored in collections, which are made up of individual documents. Each document contains fields, which can be of different data types, such as strings, numbers, dates, and arrays.
MongoDB also supports dynamic schema, meaning that records in a collection do not need the same structure. This allows developers to work with data evolving, making it easier to adapt to changing requirements.


For years MongoDB has been plagued by security shortcomings, much like other NoSQL database systems. Here we are going to discuss the security steps that can be taken to overcome this issue. VPSie makes it easy to install mongodb in just a few clicks JOIN US , follow the article to learn more about the process.


During this tutorial, we will demonstrate how to secure the MongoDB server, 



Secure MongoDB


The first step is to launch the Mongo client. Linux users can run Mongo Put in this paragraph, replacing the placeholders with your own data. 


Next creates the user, For example : john in the admin database with the user, Admin, AnyDatabase role:


db.createUser({user:"John",pwd:"MyPassword", roles:[{role:"userorAdminorAnyDatabase",db:"admin"}]})


Sample Output

  user: "John", 
  pwd: "MyPASSWORD", 
  roles: [
      role: "userorAdminorAnyDatabase",
      db: "admin"


You can now exit the mongo client and edit your MongoDB configuration file. In the following commands, you will find it depending on your operating system and distribution.




Please change the line, “security” : to the following:


  authorization: enabled


We recommend setting the bind port to localhost ( or to a private IP address that will not be exposed to the internet. 


Basically, you shouldn’t publish your database on the internet.



# network interfaces
  port: 27017


Restart your MongoDB database. Your Linux distro will determine which command you should run. 


systemctl restart mongodb
systemctl restart mongodb

we hope that this article has provided you with more information.



Comparing MongoDB to Other Databases

MongoDB is often compared to traditional relational databases, such as MySQL and PostgreSQL. While these databases have been the go-to choice for many applications over the years, they have some limitations that MongoDB addresses.


One of the main dissimilarities between MongoDB and traditional databases is how they store data. While conventional databases use tables, rows, and columns, MongoDB stores data in collections and documents. This makes working with data that needs to be well-structured or changes frequently makes it more accessible.


Another key difference is the way that MongoDB handles relationships between data. While traditional databases use foreign keys to link related data in different tables, MongoDB uses a concept called embedding. This means associated data can be stored within the same document, making it faster and easier to retrieve.


MongoDB Use Cases

MongoDB is a versatile database that can be used in various applications. Some of the most general use cases include:

  1. Content Management Systems (CMS) – MongoDB is a popular choice for CMS applications. It can store a wide range of data, including text, images, videos, and other media.
  2. E-commerce – MongoDB is a good fit for e-commerce applications, where it can store product, customer, and order data.
  3. Social Media – MongoDB is well-suited for social media applications, which can store user profiles, messages, comments, and other data.
  4. IoT – MongoDB is a good choice for IoT applications, where it can be used to store sensor data, device data, and other telemetry data.

MongoDB Features

MongoDB has many features, making it a robust database for modern applications. Some of the key features include:

  1. Flexible Data Model – MongoDB’s document-based data model is highly flexible, allowing developers to work with data like how they work with objects in their code.
  2. Scalability – MongoDB is designed to scale horizontally, allowing it to handle large volumes of data and traffic. It can be run on clusters of servers, and new nodes can be added to the collection as needed.
  3. Indexing – MongoDB supports many indexing options, including single-field, compound, text, and geospatial indexes. This makes it fast and easy to retrieve data from extensive collections.
  4. Aggregation Framework – MongoDB’s robust aggregation framework allows developers to perform complex queries and data transformations on large datasets.
  5. Security – MongoDB includes built-in security features, including authentication, authorization, and encryption, to help protect data from unauthorized access.


Advantages of MongoDB

  1. Scalability – MongoDB is designed to scale horizontally, allowing it to handle large volumes of data and traffic.
  2. Flexibility – MongoDB’s document-based data model is highly flexible, allowing developers to work with data in a way similar to how they work with objects in their code.
  3. Performance – MongoDB’s architecture is designed for high performance, making it a good choice for applications that require fast data access.
  4. Cost-effective – MongoDB is open source, meaning it is free to use and can be deployed on commodity hardware.
  5. Community Support – MongoDB has a large and active community of developers and users who subscribe to its development and provide support and resources for other users.


Disadvantages of MongoDB

  1. Lack of Transactions – MongoDB does not support multi-document transactions, which can make it difficult to ensure data consistency in complex applications.
  2. Limited Querying Capabilities – MongoDB’s query language is less potent than SQL, making it more challenging to perform complex queries and transformations on data.
  3. Memory Usage – MongoDB can consume much memory, particularly on large datasets.
  4. Data Size Limitations – MongoDB has a limit of 16MB for individual documents, making storing large amounts of data in a single copy difficult.


MongoDB is a powerful, flexible, scalable database well-suited for modern applications. Its document-based data model, scalability, and flexibility make it popular for various applications, including CMS, e-commerce, social media, and IoT.

While MongoDB has some limitations, such as the lack of multi-document transactions and limited Querying capabilities, it remains a popular choice for many developers and organizations. Its open-source nature, large and active community, and powerful features make it a compelling option for modern application development.

Improve Your MongoDB Security


MongoDB is a popular NoSQL database that uses JSON-like documents to store data in a document format.

MongoDB stores sensitive data, and if it is not appropriately secured, it can be vulnerable to cyberattacks such as data breaches, denial-of-service attacks, and unauthorized access.

Here are some simple ways to secure MongoDB:

  1. Use strong passwords: Ensure that your MongoDB instance has a strong password. Avoid using default or weak passwords like “123456” or “password.”
  2. Enable authentication: MongoDB supports authentication, which requires a username and password to access the database. Ensure that authentication is enabled in your MongoDB instance.
  3. Use role-based access control: MongoDB provides role-based access control (RBAC), allowing you to define and assign roles to users. Use RBAC to control access to your MongoDB instance.
  4. Keep your MongoDB instance up-to-date: Ensure that your MongoDB instance is up-to-date with the latest security patches and updates.
  5. Configure network security: Use network security measures such as firewalls and VPNs to secure your MongoDB instance from unauthorized access.
  6. Enable SSL/TLS encryption: MongoDB supports SSL/TLS encryption, which encrypts data in transit between the client and the server. Enable SSL/TLS encryption to secure data transmission.
  7. Use the least privilege: Grant the minimum required privileges to users and roles to prevent unauthorized access to your MongoDB instance.

If you suspect a security breach in your MongoDB instance, immediately disconnect your MongoDB instance from the network and contact your security team. Review your MongoDB instance’s logs to identify the source and scope of the breach. Take corrective action to secure your MongoDB instance and prevent future breaches.

You can use security monitoring tools like MongoDB Compass, MongoDB Cloud, and MongoDB Ops Manager to monitor your MongoDB instance for security threats.

Ensure that your backups of MongoDB data are secure by using encryption and access controls. Store backups in a secure location and test the restore process periodically to ensure it works correctly.
