MongoDB is a popular open-source NoSQL database that is used to store the data. It is famous because of its flexible and scheme-free format, in which data is stored in BSON(binary json) format documents. These databases are dynamic in nature and contain a variable number of fields.

Since this is a database that stores sensitive information, it is the organization’s top priority to ensure that it remains secure and accessible at all times. The risks associated with it and other security concerns can be reduced with the use of strong security parameters. Let’s talk about the various ways that it could be used.

What are the different ways to secure MongoDB?

In order to prevent data breaches, illegal access, and other serious security issues, MongoDB must be properly secured. In this section, we’ll talk more about that.

Role based access control in Mongodb


A user can have one or more roles assigned to them, each with its own set of permissions. If a user has several roles, it is clear that he has access to all of the privileges listed. There are predefined roles in MongoDB, and administrators can also build new roles as needed. Read/write, dbAdmin, userAdmin, and clusterAdmin are all examples of predefined roles. The administrator can provide a custom role the ability to search, add, edit, or delete data. That’s why a user with that privilege needs to exercise extra caution.

After a role has been defined, the administrator can provide it to a user, and a user can have as many roles as he needs (depending on the requirements of the business). We’re aware that role users have complete access to the system, thus it’s up to the administrator to ensure that the user has the bare minimum of permissions necessary to execute his job. It decreases the possibility of accidental and intentional misuse.


user: “NormalUser”,

pwd: “NormalPassword”,

roles: [“clusterAdmin”]
