Event Information

  • The google.cloud.bigquery.v2.DatasetService.InsertDataset event in GCP for BigQuery refers to the creation of a new dataset in BigQuery.
  • This event is triggered when a user or application creates a new dataset within their BigQuery project.
  • It signifies the successful creation of a dataset and allows for tracking and auditing of dataset creation activities in BigQuery.

​
Examples

  1. Unauthorized access: If security is impacted with google.cloud.bigquery.v2.DatasetService.InsertDataset in GCP for BigQuery, it could indicate that unauthorized users are able to create or modify datasets within the project. This could lead to potential data breaches or unauthorized access to sensitive information.
  2. Data leakage: Another security impact could be the inadvertent exposure of sensitive data. If the InsertDataset operation is not properly secured, it may allow for the creation of datasets that contain sensitive information, which can then be accessed by unauthorized individuals or entities.
  3. Malicious activity: A security impact could also involve the insertion of malicious datasets. If the InsertDataset operation is compromised, an attacker could create datasets that contain malicious code or data, potentially leading to the execution of unauthorized actions or compromising the integrity of the system.

Remediation

​
Using Console

  1. Enable audit logging for BigQuery:
    • Go to the GCP Console and navigate to the BigQuery section.
    • Select the dataset or project for which you want to enable audit logging.
    • Click on “Show Info Panel” on the right side of the screen.
    • Under the “Audit logs” section, click on “Edit”.
    • Enable the desired audit logs, such as “Admin Activity” and “Data Access”.
    • Click on “Save” to enable audit logging for BigQuery.
  2. Implement access controls and permissions:
    • Go to the GCP Console and navigate to the IAM & Admin section.
    • Select the project or organization for which you want to manage access controls.
    • Click on “IAM” to view and manage IAM roles and permissions.
    • Assign appropriate roles to users and service accounts based on their responsibilities.
    • Use the principle of least privilege and grant only the necessary permissions.
    • Regularly review and update access controls to ensure they align with the principle of least privilege.
  3. Enable VPC Service Controls:
    • Go to the GCP Console and navigate to the VPC Service Controls section.
    • Create a new perimeter or select an existing perimeter.
    • Add BigQuery as a protected service within the perimeter.
    • Configure the allowed access levels and restricted access policies as per your requirements.
    • Apply the perimeter to the desired projects or organizations.
    • Regularly review and update the VPC Service Controls configuration to align with your security policies and requirements.

​
Using CLI

  1. Enable audit logging for BigQuery:
    • Use the bq update command to enable audit logging for BigQuery datasets: 
      bq update --audit_log_flag=true <project_id>:<dataset_id>
  2. Implement access controls for BigQuery:
    • Use the bq update command to set appropriate access controls for BigQuery datasets: 
      bq update --view=<view_definition> --description=<description> <project_id>:<dataset_id>.<table_id>
  3. Enable encryption at rest for BigQuery:
    • Use the bq update command to enable encryption at rest for BigQuery datasets: 
      bq update --encryption_configuration=<encryption_configuration> <project_id>:<dataset_id>

​
Using Python

To remediate the issues mentioned in the previous response for GCP BigQuery using Python, you can follow these steps:
  1. Enforce strong access controls:
    • Use the google-cloud-bigquery library in Python to manage access controls for BigQuery datasets and tables.
    • Implement the principle of least privilege by granting only necessary permissions to users and service accounts.
    • Regularly review and audit access controls to ensure they align with the principle of least privilege.
  2. Enable audit logging:
    • Use the google-cloud-logging library in Python to enable audit logging for BigQuery.
    • Configure the logging to capture relevant events, such as dataset creation, table deletion, and access control changes.
    • Store the logs in a secure location, such as Cloud Storage or BigQuery, for further analysis and monitoring.
  3. Implement data encryption:
    • Use the google-cloud-kms library in Python to encrypt sensitive data stored in BigQuery.
    • Generate and manage encryption keys using Google Cloud Key Management Service (KMS).
    • Configure BigQuery to encrypt data at rest and in transit to ensure data confidentiality.
Please note that the provided steps are high-level guidelines, and you may need to adapt them based on your specific requirements and environment. The Python scripts for implementing these steps can be quite extensive and may vary depending on your use case. It is recommended to refer to the official documentation and examples provided by Google Cloud for detailed implementation guidance.
