1. Open the AWS Management Console and navigate to the EC2 service.
2. From the navigation pane, click on the “Load Balancers” option.
3. Select the ELB that you want to remediate and click on its name to open its details page.
4. In the “Attributes” section of the details page, locate the “Deletion Protection” option and click on the “Edit” button next to it.
5. Select the checkbox next to “Enable deletion protection” and click on the “Save” button to enable deletion protection for the ELB.
6. Once the deletion protection is enabled, you will see a lock icon next to the ELB name indicating that it is protected from accidental deletion.
7. Repeat the above steps for all the ELBs that need to be remediated.

​

1. Open your AWS CLI and run the following command to enable deletion protection on all your ELBs:

aws elb modify-load-balancer-attributes --load-balancer-name <ELB_NAME> --attributes "{\"DeletionProtection\":{\"Value\":true}}"

2. To verify that the deletion protection flag is enabled, run the following command:

aws elb describe-load-balancers --load-balancer-name <ELB_NAME> --query 'LoadBalancerDescriptions[*].[LoadBalancerName, Scheme, DeletionProtection]'

3. If the deletion protection flag is not enabled, repeat step 1 for all the ELBs that you want to enable deletion protection for.

1. Import the necessary AWS SDK modules:

import boto3
from botocore.exceptions import ClientError

2. Initialize a boto3 client for Elastic Load Balancing:

elb_client = boto3.client('elbv2')

3. Get a list of all the existing ELBs in your AWS account:

try:
    response = elb_client.describe_load_balancers()
    elbs = response['LoadBalancers']
except ClientError as e:
    print(e)

4. For each ELB, check if the deletion protection flag is enabled. If not, enable it:

for elb in elbs:
    elb_name = elb['LoadBalancerName']
    try:
        response = elb_client.modify_load_balancer_attributes(
            LoadBalancerArn=elb['LoadBalancerArn'],
            Attributes=[
                {
                    'Key': 'deletion_protection.enabled',
                    'Value': 'true'
                }
            ]
        )
        print(f"Deletion protection enabled for ELB {elb_name}")
    except ClientError as e:
        print(e)

5. Run the Python script to enable deletion protection for all the ELBs in your AWS account.
