AWS EC2 Hibernation Should Be Enabled
More Info:
The Hibernation feature should be enabled for EBS-backed EC2 instances to retain memory state across instance stop/start cycles.

Triage and Remediation
Remediation
Sure, I can help you with that. Here are the step-by-step instructions to remediate the AWS EC2 hibernation misconfiguration using the AWS console:
-
Login to your AWS console and navigate to the EC2 dashboard.
-
Select the EC2 instance for which you want to enable hibernation.
-
Click on the ‘Actions’ button and select ‘Instance Settings’ from the dropdown.
-
Click on the ‘Enable Hibernation’ option.
-
A pop-up window will appear, click on ‘Enable’ to confirm the action.
-
Once hibernation is enabled, you need to stop and start the instance to apply the changes. Click on the ‘Actions’ button and select ‘Instance State’ from the dropdown.
-
Click on ‘Stop’ to stop the instance.
-
Once the instance is stopped, click on ‘Start’ to start the instance again.
-
After the instance is started, hibernation will be enabled.
That’s it! You have successfully remediated the AWS EC2 hibernation misconfiguration using the AWS console.
To remediate the misconfiguration of AWS EC2 Hibernation not being enabled, follow these steps using AWS CLI:
- Open the AWS CLI on your local machine and run the following command to enable hibernation for all instances in the region:
aws ec2 modify-instance-attribute --instance-id <instance-id> --hibernation-options Configured=true
Note: Replace <instance-id> with the actual instance ID of the instance for which you want to enable hibernation.
- Once you have enabled hibernation for all instances in the region, you can verify the same by running the following command:
aws ec2 describe-instances --instance-ids <instance-id> --query 'Reservations[].Instances[].HibernationOptions'
Note: Replace <instance-id> with the actual instance ID of the instance for which you enabled hibernation.
-
If the output of the above command shows that hibernation is enabled, then you have successfully remediated the misconfiguration. If not, then you can try enabling hibernation again using the first command.
-
Repeat the above steps for all instances in the region to ensure that hibernation is enabled for all instances.
Note: Enabling hibernation may require stopping and starting the instance. Make sure to plan accordingly and schedule any necessary downtime.
To remediate the misconfiguration in AWS EC2 Hibernation should be enabled, you can follow the below steps using Python:
-
First, you need to install the AWS SDK for Python (Boto3) using the following command:
pip install boto3 -
Next, you need to create a Boto3 client for EC2 using the following code:
import boto3 ec2 = boto3.client('ec2') -
Then, you can use the describe_instances() method to get a list of all instances in your AWS account:
instances = ec2.describe_instances() -
Next, you can loop through each instance and check if hibernation is enabled using the describe_instance_attribute() method:
for instance in instances['Reservations']: instance_id = instance['Instances'][0]['InstanceId'] hibernation_enabled = ec2.describe_instance_attribute(InstanceId=instance_id, Attribute='hibernation')['Hibernation']['Value'] -
If hibernation is not enabled, you can use the modify_instance_attribute() method to enable it:
if not hibernation_enabled: ec2.modify_instance_attribute(InstanceId=instance_id, HibernationOptions={'Configured': True}) -
Finally, you can print a message indicating that hibernation has been enabled:
print(f'Hibernation has been enabled for instance {instance_id}')
By following these steps, you can remediate the misconfiguration in AWS EC2 Hibernation should be enabled using Python.
