Event Information

  • The google.cloud.run.v1.Jobs.CreateDomainMapping event in GCP for CloudRun signifies the creation of a domain mapping for a Cloud Run service.
  • This event indicates that a custom domain has been configured to point to a specific Cloud Run service, allowing users to access the service using a custom domain name.
  • The event provides information about the domain mapping, such as the domain name, the associated Cloud Run service, and any additional configuration settings applied during the mapping creation process.

​
Examples

  1. Inadequate access controls: If security is impacted with google.cloud.run.v1.Jobs.CreateDomainMapping in GCP for CloudRun, it could be due to inadequate access controls. For example, if the user or service account performing the operation has overly permissive IAM roles or permissions, it could lead to unauthorized access to domain mapping resources. To mitigate this, it is important to follow the principle of least privilege and ensure that only the necessary permissions are granted to the user or service account.

  2. Weak authentication mechanisms: Another potential security impact could be related to weak authentication mechanisms. If the CreateDomainMapping operation allows for insecure or weak authentication methods, it could expose the domain mapping to unauthorized access or potential attacks. It is crucial to enforce strong authentication mechanisms, such as using secure tokens or certificates, to ensure the integrity and confidentiality of the domain mapping process.

  3. Lack of encryption: Security could also be impacted if the CreateDomainMapping operation does not enforce encryption for sensitive data. For example, if the operation allows for the transmission of domain mapping information over unencrypted channels, it could expose the data to interception or tampering. To address this, it is important to enforce encryption protocols, such as TLS, to protect the confidentiality and integrity of the data during transit.

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 configure the VPC Service Controls for the Cloud Run service.
    • Save the changes and wait for the configuration to take effect.

  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.
    • Save the changes and ensure that the IAM roles are properly configured.

  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 capture audit logs for the service.
    • Configure the desired log retention period and log sink destination.
    • Save the changes and verify that the Cloud Audit Logging is enabled and functioning correctly.

​
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 and Access Management (IAM) roles and permissions:
  • Use the following command to grant the necessary IAM roles to the appropriate users or service accounts: 
    gcloud projects add-iam-policy-binding [PROJECT_ID] \
--member=[MEMBER] \
--role=[ROLE]
  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 providing complete Python scripts within the response is not feasible due to the character limit. However, you can refer to the official documentation and examples provided by Google Cloud for detailed implementation steps and code samples.
