Cloud Storage Deletion

Cloud Storage Deletion refers to the removal or destruction of cloud storage infrastructure, such as buckets, containers, or directories, within a cloud environment. Monitoring this activity is critical to detecting potential unauthorized or malicious actions, such as data destruction by adversaries or accidental deletions that may lead to data loss. Examples:

  • AWS S3 Bucket Deletion: An AWS user deletes an S3 bucket using the DeleteBucket API call.
  • Azure Blob Storage Container Deletion: A user deletes a container in Azure Blob Storage using the Delete Container operation.
  • Google Cloud Storage Bucket Deletion: A Google Cloud user deletes a bucket using the storage.buckets.delete API.
  • OpenStack Swift Container Deletion: A user deletes a container in OpenStack Swift using the DELETE method.

This data component can be collected through the following measures:

Enable Logging for Cloud Storage Services

  • AWS S3: Enable AWS CloudTrail to log DeleteBucket API actions.
  • Azure Blob Storage: Enable Azure Monitor and Diagnostic Logs to capture Delete Container operations. Use Azure Event Grid to capture and trigger alerts for container deletion.
  • Google Cloud Storage: Enable Data Access logs in Cloud Audit Logs to monitor storage.buckets.delete API calls.
  • OpenStack Swift: Configure Swift logging to capture DELETE requests for containers.

Centralized Logging and Analysis

  • Use platforms like Splunk or native SIEMs to forward and analyze logs for anomalies in cloud storage deletions.
