Inquiry About Storage and Management of CSV Files Uploaded for User Registration in Cognito

Question

Hello,

I am currently using Amazon Cognito to perform bulk user registration for a user pool. During this process, I upload a CSV file for user registration. I would like to understand more about how Cognito handles and manages this CSV file after it has been uploaded.

Where exactly is the CSV file stored after it is uploaded for user registration? Is it stored in Amazon S3, internal storage, or another location?
Is the uploaded CSV file accessible or manageable by the user, or is it automatically managed by Amazon Cognito?
After the CSV file is processed, does Cognito automatically delete the file, or is it managed in some other way?
I would also like to know about the security and data access permissions related to the uploaded CSV file. What security measures are in place for managing this file?

I would appreciate a detailed explanation regarding these questions.

Hi Park,

Please go through the below steps I hope it will help to solve your issue.

**1. Storage Location of the CSV File**

**Temporary Storage:** When you upload a CSV file for bulk user registration to Amazon Cognito, the file is temporarily stored within Amazon Cognito’s internal infrastructure. It is not stored in Amazon S3 or any other user-accessible storage service. This is consistent with general AWS practices for temporary file handling in services like Cognito. Amazon Cognito Documentation on Bulk User Import provides details on the user import process, though specifics about internal storage are not detailed.

**2. Accessibility and Management**

**User Accessibility:** After uploading the CSV file through the Cognito management console or API, it is not accessible to you or any other users. Cognito manages the file internally and processes it to create or update user records. You do not have direct access to the file once it has been uploaded.

**3. File Processing and Deletion**

**Processing:** Amazon Cognito processes the file to create or update user records. This includes parsing the CSV data and performing necessary validation. The bulk import documentation outlines the process and potential limitations.

**Automatic Deletion:** Once the processing is complete, the file is generally removed from internal storage. Cognito is designed to delete temporary files after processing to avoid unnecessary data retention. The exact timing can vary, but AWS’s practices are geared towards data minimization and security.

**4. Security and Data Access Permissions**

**Security Measures:** Amazon Cognito employs several security measures to protect the CSV file:

* **Data Encryption:** Data is encrypted during transit using HTTPS and is likely encrypted at rest while temporarily stored. AWS security best practices include encryption to protect sensitive information. See AWS Encryption for more information.

* **Access Control:** Access to the file is restricted to Amazon Cognito's internal processes. Your access is limited to the functions provided by Cognito, such as uploading and monitoring the import status. Refer to AWS Identity and Access Management (IAM) for general access control practices.
