1. Open the GCP console and navigate to the Load Balancing page.
2. Select the Load Balancer that you want to remediate.
3. Click on the Edit button to edit the Load Balancer configuration.
4. In the Edit Load Balancer page, scroll down to the Security section.
5. Under the Security section, click on the Edit button next to the SSL policy field.
6. In the Edit SSL policy page, select a SSL policy that does not allow weak cipher suites.
7. Click on the Save button to save the changes.
8. Once the SSL policy is updated, click on the Update button to update the Load Balancer configuration.
9. Wait for the changes to propagate across all the resources associated with the Load Balancer.
10. Verify that the Load Balancer is no longer allowing weak cipher suites.

​

1. Open the Cloud Shell in the GCP console.
2. Run the following command to list all the load balancers in your project:

gcloud compute url-maps list

3. Note down the name of the load balancer that you want to remediate.
4. Run the following command to describe the load balancer:

gcloud compute url-maps describe [LOAD_BALANCER_NAME]

5. In the output, look for the “sslPolicy” field. If the value is set to “ssl-policy-minimal”, then the load balancer is using the default SSL policy which allows weak cipher suites.
6. Run the following command to update the SSL policy of the load balancer:

gcloud compute url-maps set-ssl-policy [LOAD_BALANCER_NAME] --ssl-policy=[SSL_POLICY_NAME]

7. Verify that the SSL policy has been updated by running the following command:

gcloud compute url-maps describe [LOAD_BALANCER_NAME]

1. Install the Google Cloud SDK on your local machine and authenticate using your Google Cloud account credentials.
2. Use the Cloud Load Balancing API to get a list of all the load balancers in your GCP project.
3. For each load balancer, retrieve its SSL policy using the get_ssl_policy() method.
4. Check if the SSL policy allows weak cipher suites by iterating over the ciphers list and looking for any ciphers that are considered weak.
5. If any weak cipher suites are found, create a new SSL policy with the same settings as the existing policy but with the weak ciphers removed using the create_ssl_policy() method.
6. Update the load balancer to use the new SSL policy using the set_ssl_policy() method.
