Kms app tier remediation

Using Console

Using CLI

To remediate the “App-tier KMS Key Should Be In Use” misconfiguration for AWS using AWS CLI, follow these steps:

Log in to the AWS Management Console.
Open the AWS CLI and run the following command to check if the KMS key is in use:
```
aws kms list-aliases
```
This command will list all the KMS keys available in your account.
Identify the KMS key that should be used for the App-tier and note down its ARN.
Open the AWS CLI and run the following command to update the App-tier to use the correct KMS key:
```
aws elasticbeanstalk update-environment --environment-name <environment-name> --option-settings Namespace=aws:elasticbeanstalk:application:environment,OptionName=APP_TIER_KMS_KEY_ID,Value=<KMS-key-ARN>
```
Replace <environment-name> with the name of the environment that needs to be updated, and <KMS-key-ARN> with the ARN of the correct KMS key.
Verify that the update was successful by running the following command:
```
aws elasticbeanstalk describe-environments --environment-names <environment-name>
```
This command will return the details of the environment. Check that the APP_TIER_KMS_KEY_ID option is set to the correct KMS key ARN.
Repeat the above steps for all environments in your AWS account that are affected by this misconfiguration.

Using Python

To remediate the “App-tier KMS Key Should Be In Use” misconfiguration in AWS using Python, you can follow these steps:

First, you need to identify the App-tier KMS Key that should be used. You can do this by checking your AWS account to see if there is a KMS Key that is specifically designated for use with your App-tier resources. If there is, note down the ARN of the KMS Key.
Next, you need to update your App-tier resources to use the designated KMS Key. You can do this by using the AWS SDK for Python (Boto3) to modify the resources’ encryption settings. Here’s an example code snippet that shows how to do this for an EC2 instance:

import boto3

# Replace the values in the following variables with your own values
instance_id = 'your-instance-id'
kms_key_arn = 'your-kms-key-arn'

# Create a Boto3 EC2 client
ec2 = boto3.client('ec2')

# Modify the instance's encryption settings to use the designated KMS Key
response = ec2.modify_instance_attribute(
    InstanceId=instance_id,
    BlockDeviceMappings=[
        {
            'DeviceName': '/dev/sda1',
            'Ebs': {
                'Encrypted': True,
                'KmsKeyId': kms_key_arn
            }
        }
    ]
)

This code modifies the encryption settings of the root EBS volume of an EC2 instance to use the designated KMS Key.

Finally, you should verify that the App-tier resources are now using the designated KMS Key. You can do this by checking the encryption settings of the resources using the AWS Management Console or the AWS CLI.

By following these steps, you should be able to remediate the “App-tier KMS Key Should Be In Use” misconfiguration in AWS using Python.
