Not using default port remediation

Using Console

Using CLI

To remediate the misconfiguration of Redshift clusters using the default port in AWS, you can follow these steps using the AWS CLI:Step 1: List the existing Redshift clusters to identify the clusters using the default port (5439) by running the following command:

aws redshift describe-clusters

Step 2: Identify the Redshift cluster for which you want to update the port and make a note of the Cluster Identifier.Step 3: Modify the cluster to change the port using the modify-cluster command. Replace <cluster-identifier> with the actual Cluster Identifier and <new-port> with the desired port number (e.g., 5432) by running the following command:

aws redshift modify-cluster --cluster-identifier <cluster-identifier> --port <new-port>

Step 4: Verify the port change by describing the cluster again and checking if the port has been updated successfully:

aws redshift describe-clusters --cluster-identifier <cluster-identifier>

By following these steps, you can remediate the misconfiguration of Redshift clusters using the default port in AWS Redshift using the AWS CLI.

Using Python

To remediate the misconfiguration of Redshift clusters using the default port in AWS, you can use the AWS SDK for Python (Boto3) to update the cluster’s port to a non-default value. Here are the step-by-step instructions to remediate this misconfiguration:

Install Boto3: If you haven’t already installed the Boto3 library, you can install it using pip:
```
pip install boto3
```

Update Redshift Cluster Port: Use the following Python script to update the port for your Redshift cluster. Replace <cluster_id> with the ID of your Redshift cluster and <new_port> with the desired non-default port value:

import boto3

redshift = boto3.client('redshift')

cluster_id = '<cluster_id>'
new_port = <new_port>

response = redshift.modify_cluster(
    ClusterIdentifier=cluster_id,
    ClusterParameterGroupName='default',
    AutomatedSnapshotRetentionPeriod=1,
    Port=new_port
)

print(f"Updated port for Redshift cluster {cluster_id} to {new_port}")

Run the Python Script: Save the above script in a file (e.g., update_redshift_port.py) and run it using Python:
```
python update_redshift_port.py
```
Verify the Port Update: You can verify that the port for your Redshift cluster has been updated successfully by checking the cluster details in the AWS Management Console or by running describe-cluster CLI command.

By following these steps, you can remediate the misconfiguration of Redshift clusters using the default port in AWS.
