Node-to-Node Encryption Should Be Enabled OpenSearch Service Domains

More Info:

This rule checks whether Amazon OpenSearch Service nodes are encrypted end-to-end. Node-to-node encryption ensures that communication between nodes within the OpenSearch domain is encrypted, enhancing the security of data transmission. The rule is marked as non-compliant if node-to-node encryption is not enabled on the domain.

Using CLI

To remediate the misconfiguration of enabling Node-to-Node Encryption for AWS OpenSearch Service domains using AWS CLI, you can follow these steps:

Enable Node-to-Node Encryption: Run the following AWS CLI command to enable Node-to-Node encryption for your OpenSearch Service domain:
```
aws opensearchservice update-domain-config --domain-name YOUR_DOMAIN_NAME --node-to-node-encryption-options Enabled=true
```
Replace YOUR_DOMAIN_NAME with the name of your OpenSearch Service domain.
Verify Node-to-Node Encryption: You can verify that Node-to-Node encryption is enabled for your OpenSearch Service domain by describing the domain configuration:
```
aws opensearchservice describe-domain-config --domain-name YOUR_DOMAIN_NAME
```
Ensure that the NodeToNodeEncryptionOptions parameter shows Enabled: true.
Monitor the Configuration: It is recommended to monitor the OpenSearch Service domain for any issues after enabling Node-to-Node encryption to ensure that the domain continues to function properly.

By following these steps, you can successfully remediate the misconfiguration of enabling Node-to-Node Encryption for AWS OpenSearch Service domains using the AWS CLI.

Using Python

To remediate the misconfiguration of enabling Node-to-Node Encryption for AWS OpenSearch Service domains using Python, you can utilize the AWS SDK for Python (Boto3) to update the domain configuration. Here are the step-by-step instructions to remediate this issue:

Install Boto3: Ensure you have Boto3 installed in your Python environment. You can install it using pip:

pip install boto3

Update OpenSearch Domain Configuration: Create a Python script with the following code to update the OpenSearch domain configuration to enable Node-to-Node Encryption:

import boto3

def update_opensearch_domain_config(domain_name):
    client = boto3.client('es')
    
    response = client.update_elasticsearch_domain_config(
        DomainName=domain_name,
        NodeToNodeEncryptionOptions={
            'Enabled': True
        }
    )
    
    print(f"Node-to-Node Encryption enabled for OpenSearch domain {domain_name}")

# Replace 'your-opensearch-domain-name' with the actual OpenSearch domain name
update_opensearch_domain_config('your-opensearch-domain-name')

Configure AWS Credentials: Ensure that your AWS credentials are properly configured either through environment variables, AWS CLI configuration, or IAM roles.
Run the Python Script: Execute the Python script you created in step 2. This script will update the specified OpenSearch domain configuration to enable Node-to-Node Encryption.

After running the script, the Node-to-Node Encryption should be successfully enabled for the specified AWS OpenSearch Service domain.
