Using CLI
Using CLI
To remediate the issue of an AWS Redshift cluster being publicly accessible, follow these steps using the AWS CLI:Step 1: List all the Redshift clusters in your AWS account to identify the cluster that is publicly accessible.Step 2: Identify the Redshift cluster that is publicly accessible by checking the value of the After running these commands, your AWS Redshift cluster should no longer be publicly accessible. Make sure to replace
PubliclyAccessible parameter in the cluster description.Step 3: Modify the Redshift cluster to make the cluster not publicly accessible by updating the cluster’s security group. Replace your-security-group-id with the appropriate security group ID of your Redshift cluster.your-cluster-identifier and your-security-group-id with the actual values for your Redshift cluster.Using Python
