Ec2 instance generation remediation

Using Console

Using CLI

To remediate the misconfiguration “EC2 Instances Should Use Latest Generation” for AWS using AWS CLI, follow the below steps:

Open the AWS CLI on your local machine.
Run the following command to list all the EC2 instances in your AWS account:

aws ec2 describe-instances

Identify the instances that are not using the latest generation.
Stop the instance using the following command:

aws ec2 stop-instances --instance-ids <instance-id>

Make sure to replace <instance-id> with the actual ID of the instance that needs to be stopped.

Once the instance is stopped, update the instance type to the latest generation using the following command:

aws ec2 modify-instance-attribute --instance-id <instance-id> --instance-type <instance-type>

Replace <instance-id> with the actual ID of the instance that needs to be updated, and <instance-type> with the latest generation instance type.

Start the instance using the following command:

aws ec2 start-instances --instance-ids <instance-id>

Make sure to replace <instance-id> with the actual ID of the instance that needs to be started.

Verify that the instance is running and using the latest generation instance type.

Repeat the above steps for all the instances that are not using the latest generation.

Using Python

To remediate the EC2 Instances Should Use Latest Generation misconfiguration for AWS using Python, you can follow these steps:

Identify all the EC2 instances running in your AWS account that are not using the latest generation.
Use the AWS SDK for Python (Boto3) to create a list of all the instances that are not using the latest generation.
Use the Boto3 EC2 client to stop the instances that are not using the latest generation.
Use the Boto3 EC2 client to modify the instance type to the latest generation.
Use the Boto3 EC2 client to start the instances again.

Here is a sample Python code that can be used to remediate the EC2 Instances Should Use Latest Generation misconfiguration in AWS:

import boto3

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

# Get a list of all the instances in the account
response = ec2.describe_instances()

# Loop through all the instances and check if they are using the latest generation
for reservation in response['Reservations']:
    for instance in reservation['Instances']:
        instance_type = instance['InstanceType']
        latest_generation_instance_types = ['t3', 'm5', 'c5', 'r5']
        if not any(instance_type.startswith(prefix) for prefix in latest_generation_instance_types):
            instance_id = instance['InstanceId']
            # Stop the instance
            ec2.stop_instances(InstanceIds=[instance_id])
            # Modify the instance type to the latest generation
            ec2.modify_instance_attribute(InstanceId=instance_id, Attribute='instanceType', Value='t3.micro')
            # Start the instance
            ec2.start_instances(InstanceIds=[instance_id])

Note: This code assumes that the latest generation instance type is t3.micro. You may need to modify the instance type value based on your specific requirements.
