Google.cloud.apigateway.v1.apigatewayservice.deleteapi

​

Event Information

• The google.cloud.apigateway.v1.ApiGatewayService.DeleteApi event in GCP for APIGateway indicates that an API has been deleted from the API Gateway service.
• This event signifies that the specified API and all its associated configurations, routes, and policies have been permanently removed.
• It is important to note that this event does not affect any backend services or resources connected to the API, but only removes the API configuration from the API Gateway service.

​

Examples

1. Unauthorized access: If security is impacted with the google.cloud.apigateway.v1.ApiGatewayService.DeleteApi operation in GCP API Gateway, it could potentially allow unauthorized users to delete APIs. This could lead to the loss of critical API configurations and disrupt the functionality of applications relying on those APIs.
2. Data exposure: A security impact could occur if the DeleteApi operation in GCP API Gateway does not properly handle sensitive data associated with the deleted API. This could result in the exposure of sensitive information, such as API keys, authentication credentials, or personally identifiable information (PII), to unauthorized individuals or systems.
3. Denial of Service (DoS): If security is compromised with the DeleteApi operation in GCP API Gateway, it could be exploited to launch a DoS attack. An attacker could repeatedly delete APIs, causing service disruptions and rendering the affected APIs unavailable to legitimate users. This could result in financial losses, reputational damage, and potential legal implications for the impacted organization.

Remediation

​

Using Console

1. Enable API Gateway Logging:
   • Go to the GCP Console and navigate to the API Gateway page.
   • Select the API Gateway instance for which you want to enable logging.
   • Click on the “Edit” button.
   • In the “Logging” section, enable the “Enable Logging” option.
   • Choose the desired log level (e.g., INFO, DEBUG) and log format (e.g., JSON, TEXT).
   • Click on the “Save” button to apply the changes.
2. Implement Rate Limiting:
   • Go to the GCP Console and navigate to the API Gateway page.
   • Select the API Gateway instance for which you want to implement rate limiting.
   • Click on the “Edit” button.
   • In the “Rate Limiting” section, enable the “Enable Rate Limiting” option.
   • Specify the maximum number of requests allowed per minute or per second.
   • Optionally, configure the response status code and message for exceeded limits.
   • Click on the “Save” button to apply the changes.
3. Implement Authentication and Authorization:
   • Go to the GCP Console and navigate to the API Gateway page.
   • Select the API Gateway instance for which you want to implement authentication and authorization.
   • Click on the “Edit” button.
   • In the “Authentication” section, enable the desired authentication method (e.g., API key, OAuth 2.0).
   • Configure the authentication settings, such as API key restrictions or OAuth 2.0 scopes.
   • In the “Authorization” section, enable the desired authorization method (e.g., IAM, Firebase Auth).
   • Configure the authorization settings, such as IAM roles or Firebase Auth rules.
   • Click on the “Save” button to apply the changes.

Using CLI

1. Enable logging for API Gateway:
   • Use the following command to enable logging for API Gateway:
     Copy

     Ask AI

     gcloud logging sinks create [SINK_NAME] pubsub.googleapis.com/projects/[PROJECT_ID]/topics/[TOPIC_NAME] --log-filter='resource.type="apigateway.googleapis.com/Api" AND severity>=ERROR'
     

   • Replace [SINK_NAME] with the desired name for the sink.
   • Replace [PROJECT_ID] with your GCP project ID.
   • Replace [TOPIC_NAME] with the name of the Pub/Sub topic where you want to send the logs.
2. Set up monitoring for API Gateway:
   • Use the following command to create a health check for API Gateway:
     Copy

     Ask AI

     gcloud compute health-checks create http [HEALTH_CHECK_NAME] --port=[PORT] --request-path=[REQUEST_PATH]
     

   • Replace [HEALTH_CHECK_NAME] with the desired name for the health check.
   • Replace [PORT] with the port number used by your API Gateway.
   • Replace [REQUEST_PATH] with the path used for health checks in your API Gateway.
3. Implement access controls for API Gateway:
   • Use the following command to add IAM policies for API Gateway:
     Copy

     Ask AI

     gcloud projects add-iam-policy-binding [PROJECT_ID] --member=[MEMBER] --role=[ROLE]
     

   • Replace [PROJECT_ID] with your GCP project ID.
   • Replace [MEMBER] with the email address or service account of the user or service account you want to grant access.
   • Replace [ROLE] with the desired IAM role for the user or service account.

Using Python

1. Enable logging and monitoring:
   • Use the Cloud Logging API to enable logging for your API Gateway service.
   • Set up log sinks to export logs to Cloud Monitoring or other monitoring tools.
   • Create custom metrics and alerts based on the logs to proactively detect and respond to issues.
2. Implement rate limiting:
   • Use the google-cloud-apigateway Python library to interact with the API Gateway service.
   • Set up a rate limit policy for your API using the apigateway.projects.locations.gatewayApis.update method.
   • Specify the maximum number of requests allowed per minute or per second in the rate limit policy.
3. Implement authentication and authorization:
   • Use the google-auth Python library to authenticate requests to your API Gateway service.
   • Implement OAuth 2.0 or API key-based authentication mechanisms.
   • Use the apigateway.projects.locations.gatewayApis.update method to configure authentication and authorization settings for your API.
