Protecting Sensitive Data: Mastering Queryable Encryption in MongoDB

In today’s digital landscape, safeguarding sensitive data is non-negotiable. Enter Queryable Encryption, a game-changing solution that’s here to redefine data security.

With queryable Encryption, you can encrypt your valuable information from the get-go, right at the client-side. What’s more, your data is stored in a completely randomized, indecipherable form on the server-side.

In this blog post, we’ll explore its incredible features, its practical applications, and the different ways you can put it to work for your organization.

Queryable Encryption is available from MongoDB version 7.0

Who Can Benefit from Queryable Encryption?

If you’re dealing with sensitive information like credit card details or phone numbers, even though you may already encrypt data at rest, ensuring real-time, on-the-fly data security becomes essential to meet compliance standards.

List of Keys Supported for Encryption

• AWS Key Management Service (AWS KMS)
• Google Cloud KMS
• Azure Key Vault
• Other KIMP providers

How Data is stored in Encrypted Manner?

How Data is retrieved in Encrypted Manner?

Code snippet:

1. const encryptedFieldsMap = {
2.     encryptedFields: {
3.       fields: [
4.         {
5.           path: "ProfileRecord.phone",
6.           bsonType: "int",
7.           queries: { queryType: "equality" },
8.         },
9.         {
10.           path: "ProfileRecord.email",
11.           bsonType: "object",
12.         },
13.       ],
14.     },
15.   };
16.   // end-encrypted-fields-map

As evident, the email and phone number fields have been securely encrypted within the database.

To access the data, we utilize the same encryption key to retrieve it, which will then be displayed in its original, unencrypted form.

In a nutshell, queryable encryption acts as a safeguard for sensitive information, adding an extra layer of protection for data residing at rest within the database.
