Open the GCP console and navigate to the Cloud CDN page. 2. Select the Global URL Maps tab. 3. Click on the name of the URL map that you want to modify. 4. Click on the Edit button at the top of the page. 5. In the Edit URL map page, scroll down to the Host and Path Rules section. 6. Click on the Add Host and Path Rule button. 7. In the new rule, set the Host to "\*" to match all hosts. 8. Set the Path to "/\*" to match all paths. 9. Set the Backend service to the appropriate backend service for your application. 10. Under the Protocol section, select HTTPS from the dropdown menu. 11. Click on the Save button to save the changes. Once you have completed these steps, your Global URL Map will only accept HTTPS connections. Any HTTP connections will be rejected. # To remediate the misconfiguration of Cloud CDN Global Urlmaps accepting only HTTPS connections in GCP using GCP CLI, follow the below steps: Step 1: Open the Google Cloud Console and select the project where the Cloud CDN is configured. Step 2: Open the Cloud Shell by clicking on the icon in the top right corner of the console. Step 3: Run the following command to list all the existing URL maps in the project: ``` gcloud compute url-maps list ``` Step 4: Identify the URL map that needs to be remediated. Step 5: Run the following command to update the URL map to accept only HTTPS connections: ``` gcloud compute url-maps update [URL_MAP_NAME] --default-service [BACKEND_SERVICE_NAME] --ssl-policy=global-ssl-policy ``` Replace \[URL\_MAP\_NAME] with the name of the URL map that needs to be updated and \[BACKEND\_SERVICE\_NAME] with the name of the backend service associated with the URL map. Step 6: Verify that the URL map has been updated successfully by running the following command: ``` gcloud compute url-maps describe [URL_MAP_NAME] ``` This command should return the updated URL map configuration, which should include the "sslPolicy" field set to "global-ssl-policy". By following these steps, you can remediate the misconfiguration of Cloud CDN Global Urlmaps accepting only HTTPS connections in GCP using GCP CLI. To remediate the misconfiguration "Cloud CDN Global Urlmaps Should Accept Https Connections Only" for GCP using Python, you can follow the below steps: 1. Install the required packages: ```python theme={null} !pip install google-cloud-cdn !pip install google-auth google-auth-oauthlib google-auth-httplib2 ``` 2. Authenticate with GCP: ```python theme={null} from google.oauth2 import service_account from google.cloud import cdn_v1beta1 credentials = service_account.Credentials.from_service_account_file('path/to/service_account.json') client = cdn_v1beta1.GlobalForwardingRulesClient(credentials=credentials) ``` 3. Get the list of existing global URL maps: ```python theme={null} project_id = 'your-project-id' location = 'global' parent = f'projects/{project_id}/locations/{location}' url_maps = client.list_url_maps(parent=parent) ``` 4. For each URL map, check if it has an HTTPS forwarding rule: ```python theme={null} for url_map in url_maps: https_forwarding_rule = None for forwarding_rule in url_map.host_rules[0].path_matchers[0].route_rules[0].forward_action.https_redirect.action: if forwarding_rule.https_redirect: https_forwarding_rule = forwarding_rule break if not https_forwarding_rule: print(f'URL map "{url_map.name}" does not have an HTTPS forwarding rule') ``` 5. If a URL map does not have an HTTPS forwarding rule, update it: ```python theme={null} for url_map in url_maps: https_forwarding_rule = None for forwarding_rule in url_map.host_rules[0].path_matchers[0].route_rules[0].forward_action.https_redirect.action: if forwarding_rule.https_redirect: https_forwarding_rule = forwarding_rule break if not https_forwarding_rule: url_map.host_rules[0].path_matchers[0].route_rules[0].forward_action.https_redirect.action.append( cdn_v1beta1.HttpsRedirectAction()) client.update_url_map(url_map=url_map, update_mask=['host_rules.path_matchers.route_rules.forward_action.https_redirect.action']) print(f'URL map "{url_map.name}" has been updated to only accept HTTPS connections') ``` By following these steps, you can remediate the misconfiguration "Cloud CDN Global Urlmaps Should Accept Https Connections Only" for GCP using Python. ```hcl theme={null} # URL map for your HTTPS external HTTP(S) load balancer (Cloud CDN backend) resource "google_compute_url_map" "https_url_map" { name = "HTTPS_URL_MAP_NAME" # replace with your HTTPS URL map name default_service = google_compute_backend_service.cdn_backend.self_link # Optional: host_rules / path_matchers as needed } # URL map for the HTTP listener that ONLY redirects to HTTPS # This is the URL map that must exist for the HTTP target proxy / forwarding rule. resource "google_compute_url_map" "http_redirect_url_map" { name = "HTTP_REDIRECT_URL_MAP_NAME" # replace with your HTTP URL map name # Redirect all HTTP requests to the HTTPS LB default_url_redirect { https_redirect = true # enforce HTTPS strip_query = false # set true/false per your requirement redirect_response_code = "MOVED_PERMANENTLY_DEFAULT" # or another valid code } } # Attach the redirect URL map to the HTTP target proxy (front end) resource "google_compute_target_http_proxy" "http_proxy" { name = "HTTP_PROXY_NAME" # replace url_map = google_compute_url_map.http_redirect_url_map.self_link } # Attach the HTTPS URL map to the HTTPS target proxy (front end) resource "google_compute_target_https_proxy" "https_proxy" { name = "HTTPS_PROXY_NAME" # replace url_map = google_compute_url_map.https_url_map.self_link ssl_certificates = [google_compute_ssl_certificate.lb_cert.self_link] } # Example backend service with Cloud CDN enabled (for completeness) resource "google_compute_backend_service" "cdn_backend" { name = "CDN_BACKEND_NAME" # replace protocol = "HTTP" load_balancing_scheme = "EXTERNAL_MANAGED" timeout_sec = 30 enable_cdn = true backend { group = GOOGLE_INSTANCE_GROUP_OR_NEG_SELF_LINK # replace } } ``` This change is in-place for existing URL maps and target proxies (no forced replacement of the backend service, but front-end traffic behavior changes once applied). For verification, `terraform plan` should show: * `google_compute_url_map.http_redirect_url_map` either created or updated with a `default_url_redirect` block where `https_redirect = true`. * `google_compute_target_http_proxy.http_proxy` referencing that redirect URL map.
