1. Login to AWS Console: Go to the AWS Management Console and login to your account.
2. Navigate to Redshift Service: In the AWS Management Console, navigate to the Amazon Redshift service.
3. Select Parameter Groups: In the left-hand navigation pane, select “Parameter Groups”.
4. Identify the Parameter Group: Identify the parameter group that is associated with your Redshift cluster. This parameter group should be the one that needs to have SSL enabled.
5. Modify the Parameter Group: Select the parameter group by checking the box next to it, and then click on the “Modify” button at the top.
6. Update SSL Configuration: In the parameter group settings, locate the parameter require_ssl and set its value to true to enforce SSL connections.
7. Save Changes: After updating the require_ssl parameter, scroll to the bottom of the page and click on the “Save Changes” button to apply the configuration.
8. Apply Changes to Cluster: Once the changes are saved, you will need to apply the modified parameter group to your Redshift cluster. To do this, select your Redshift cluster, click on the “Cluster Actions” dropdown, and choose “Modify”.
9. Associate Parameter Group: In the Modify Cluster settings, select the modified parameter group from the dropdown list under the “Cluster Parameter Group” section.
10. Apply Changes: Review the other settings if needed and click on the “Modify Cluster” button to apply the changes.

​

1. List all existing Redshift parameter groups to identify the one that needs to be updated:

aws redshift describe-cluster-parameter-groups

2. Modify the Redshift parameter group to require SSL by setting the require_ssl parameter to true:

aws redshift modify-cluster-parameter-group --parameter-group-name <parameter-group-name> --parameters "ParameterName=require_ssl,ParameterValue=true,ApplyType=dynamic"

3. Apply the modified parameter group to the Redshift cluster:

aws redshift reboot-cluster --cluster-identifier <cluster-identifier>

4. Verify the changes by describing the modified Redshift parameter group:

aws redshift describe-cluster-parameters --parameter-group-name <parameter-group-name>

1. Install the boto3 library if you haven’t already. You can install it using pip:
   Copy

   pip install boto3
   

2. Use the following Python script to update the Redshift Parameter Group to require SSL:

import boto3

def update_redshift_parameter_group():
    # Specify the AWS region where your Redshift cluster is located
    region = 'your_aws_region'

    # Specify the name of the Redshift Parameter Group you want to update
    parameter_group_name = 'your_parameter_group_name'

    # Create a Redshift client
    redshift = boto3.client('redshift', region_name=region)

    # Specify the parameter to update (require_ssl)
    parameters = [
        {
            'ParameterName': 'require_ssl',
            'ParameterValue': 'true',
            'ApplyType': 'static'
        }
    ]

    # Update the Redshift Parameter Group
    response = redshift.modify_cluster_parameter_group(
        ParameterGroupName=parameter_group_name,
        Parameters=parameters
    )

    print('Redshift Parameter Group updated successfully!')

if __name__ == '__main__':
    update_redshift_parameter_group()

3. Replace 'your_aws_region' with the AWS region where your Redshift cluster is located, and 'your_parameter_group_name' with the name of the Redshift Parameter Group you want to update.
4. Run the Python script. This will update the Redshift Parameter Group to require SSL.
