Event Information

  • The google.cloud.run.v1.Services.DeleteService event in GCP for CloudRun indicates that a service has been deleted in the Cloud Run environment.
  • This event signifies that the specified service, which is a containerized application running on Cloud Run, has been removed from the platform.
  • It is important to note that deleting a service will permanently remove all associated resources, including the container image, deployment, and any allocated resources like CPU and memory.

​
Examples

  1. Unauthorized access: If security is impacted with google.cloud.run.v1.Services.DeleteService in GCP for CloudRun, it could indicate that unauthorized individuals or entities have gained access to the CloudRun service and are able to delete services without proper authorization. This could lead to the deletion of critical services, resulting in downtime or loss of data.

  2. Insider threat: Another potential security impact could be an insider threat scenario, where a trusted user or employee with legitimate access to the CloudRun service abuses their privileges to delete services. This could be intentional or accidental, but in either case, it can disrupt operations and compromise the availability of services.

  3. Misconfiguration or vulnerability exploitation: A security impact could also arise from misconfigurations or vulnerabilities in the CloudRun service itself. If an attacker identifies and exploits such weaknesses, they may be able to delete services or manipulate the service’s configuration, potentially leading to unauthorized access, data breaches, or service disruptions. Regular security assessments and vulnerability management are crucial to mitigate such risks.

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”.
    • Under the “Identity and Access Management (IAM)” tab, click on “Add Member”.
    • Add the appropriate IAM roles to restrict access to the Cloud Run service based on the principle of least privilege.

  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”.
    • Under the “Logging” tab, click on “Enable Cloud Audit Logging”.
    • Configure the desired log sink destination and retention period for the Cloud Audit 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-secrets=GOOGLE_IAP_CLIENT_ID=[CLIENT_ID]
  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 CloudRun resources.
    • Set up IAM roles and permissions to restrict access to sensitive resources and actions.
    • Use the google-auth library in Python to authenticate requests to the CloudRun API.

  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 log entries to proactively monitor and detect any suspicious activities.

  3. Implement secure coding practices:

    • Regularly update and patch your Python dependencies to ensure you are using the latest secure versions.
    • Use secure coding practices to prevent common vulnerabilities like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
    • Implement input validation and sanitization techniques to prevent malicious inputs from compromising your application.

Please note that providing specific Python scripts without understanding the specific requirements and context of your application may not be feasible. It is recommended to consult the official GCP documentation and relevant Python libraries for detailed implementation guidance.
