Event Information

  • The google.cloud.run.v1.Revisions.DeleteRevision event in GCP for CloudRun indicates that a revision of a Cloud Run service has been deleted.
  • This event is triggered when a user or an automated process deletes a specific revision of a Cloud Run service.
  • The event provides information about the deleted revision, such as its name, service name, and the project ID it belongs to.

​
Examples

  1. Unauthorized deletion: If security is impacted with google.cloud.run.v1.Revisions.DeleteRevision in GCP for CloudRun, it could mean that unauthorized individuals or processes are able to delete revisions of your CloudRun services. This could lead to the loss of critical code or configurations, potentially impacting the availability and functionality of your applications.

  2. Data exposure: Another security impact could be the exposure of sensitive data. If an unauthorized user is able to delete revisions, they may also gain access to any data stored within those revisions. This could include sensitive information such as API keys, database credentials, or other confidential data, leading to potential data breaches or unauthorized access to your systems.

  3. Service disruption: The deletion of revisions could also result in service disruption. If a critical revision is deleted, it may impact the availability of your application or cause unexpected behavior. This could lead to downtime, loss of revenue, or damage to your organization’s reputation. It is important to ensure that only authorized individuals or processes have the necessary permissions to delete revisions in order to mitigate this risk.

Remediation

​
Using Console

  1. Enable VPC Service Controls:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Enable VPC Service Controls”.
    • Follow the prompts to set up VPC Service Controls for the Cloud Run service.

  2. Implement Identity and Access Management (IAM) Roles:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Show Info Panel”.
    • Click on “Add Member” to add the appropriate IAM roles for the service.
    • Assign the necessary roles to the relevant users or service accounts.

  3. Enable Cloud Audit Logging:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Show Info Panel”.
    • Enable the “Cloud Audit Logging” option to start logging all activity related to the Cloud Run service.
    • Configure the desired log retention period and destination for the logs.

​
Using CLI

  1. Enable VPC Service Controls for Cloud Run:
  • Use the following command to enable VPC Service Controls for Cloud Run: 
    gcloud services vpc-peerings connect \
--service=servicenetworking.googleapis.com \
--network=projects/[PROJECT_ID]/global/networks/[NETWORK_NAME]
  1. Implement Identity-Aware Proxy (IAP) for Cloud Run:
  • Use the following command to configure IAP for Cloud Run: 
    gcloud beta run services update [SERVICE_NAME] \
--update-env-vars=GOOGLE_CLOUD_IAP_BACKEND_SERVICE=[BACKEND_SERVICE_NAME]
  1. Enable Cloud Audit Logging for Cloud Run:
  • Use the following command to enable Cloud Audit Logging for Cloud Run: 
    gcloud logging sinks create [SINK_NAME] \
storage.googleapis.com/projects/[PROJECT_ID]/buckets/[BUCKET_NAME] \
--log-filter='resource.type="cloud_run_revision"'

​
Using Python

To remediate the issues mentioned in the previous response for GCP CloudRun using Python, you can follow these steps:

  1. Implement proper authentication and access controls:

    • Use the Google Cloud SDK and authenticate with a service account that has the necessary permissions to access and manage CloudRun resources.
    • Use the google-auth library in Python to authenticate requests made to the CloudRun API.
    • Ensure that the service account used has the least privilege necessary to perform the required actions.

  2. Enable logging and monitoring:

    • Use the google-cloud-logging library in Python to enable logging for your CloudRun service.
    • Configure log sinks to export logs to a centralized logging solution like Stackdriver or Cloud Logging.
    • Set up alerts and notifications based on specific log events or metrics using Cloud Monitoring.

  3. Implement secure communication:

    • Use HTTPS for all incoming and outgoing requests to your CloudRun service.
    • Configure SSL certificates for your custom domains using the google-cloud-ssl-certificates library in Python.
    • Implement proper input validation and sanitization to prevent common security vulnerabilities like SQL injection or cross-site scripting (XSS).

Please note that the provided steps are high-level guidelines, and the actual implementation may vary based on your specific requirements and the structure of your Python application.
