Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer
More Info:
Ensure that your Amazon Elastic Beanstalk environment is configured to capture access logs for the load balancer associated with the application environment. An Elastic Beanstalk environment is a collection of AWS resources running an application version. When you create an environment, Amazon Elastic Beanstalk provisions the resources needed to run the application version you specified.

Remediation
To remediate the misconfiguration of “Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer” for AWS using AWS console, follow these steps:
- Sign in to the AWS Management Console.
- Navigate to the Elastic Beanstalk console.
- Select the appropriate application environment.
- In the left navigation pane, click on “Configuration”.
- Scroll down to the “Load Balancer” section and click on the “Edit” button.
- In the “Logging” section, select “Enable Access Logs”.
- Specify the S3 bucket where you want to store the access logs and provide a prefix for the log file names.
- Click on the “Save” button to save the changes.
After completing these steps, access logging will be enabled for the Elastic Beanstalk Load Balancer. The access logs will be stored in the specified S3 bucket and can be used for analysis and troubleshooting.
To remediate the misconfiguration “Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer” for AWS using AWS CLI, follow the below steps:
- Open the AWS CLI on your terminal or command prompt.
- Run the following command to enable access logging for the Elastic Beanstalk Load Balancer:
aws elasticbeanstalk update-environment --environment-name <ENVIRONMENT_NAME> --option-settings Namespace=aws:elb:loadBalancer,OptionName=AccessLogs.S3Enabled,Value=true
Replace <ENVIRONMENT_NAME> with the name of your Elastic Beanstalk environment.
- Verify that access logging is enabled for the Elastic Beanstalk Load Balancer by running the following command:
aws elasticbeanstalk describe-environments --environment-names <ENVIRONMENT_NAME> --query "Environments[].OptionSettings[?Namespace=='aws:elb:loadBalancer' && OptionName=='AccessLogs.S3Enabled'].Value" --output text
This command will return “true” if access logging is enabled, and “false” if it is not enabled.
By following these steps, you can remediate the misconfiguration “Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer” for AWS using AWS CLI.
To remediate the misconfiguration “Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer” for AWS using Python, you can follow the below steps:
- First, we need to check if the Elastic Beanstalk environment has a load balancer attached to it or not. We can use the boto3 library for this. Here is the code snippet for it:
import boto3
# Create an Elastic Beanstalk client
eb_client = boto3.client('elasticbeanstalk')
# Get the environment details
environment_name = 'your-environment-name'
environment = eb_client.describe_environments(EnvironmentNames=[environment_name])['Environments'][0]
# Get the load balancer name
load_balancer_name = environment['LoadBalancers'][0]['Name']
# Check if access logging is enabled for the load balancer
elb_client = boto3.client('elbv2')
response = elb_client.describe_load_balancers(Names=[load_balancer_name])
if response['LoadBalancers'][0]['AccessLogs']['Enabled']:
print("Access logging is already enabled for the load balancer")
else:
print("Access logging is not enabled for the load balancer")
- If access logging is not enabled for the load balancer, we can enable it by using the
modify_load_balancer_attributesmethod of theelbv2client. Here is the code snippet for it:
# Enable access logging for the load balancer
response = elb_client.modify_load_balancer_attributes(
LoadBalancerArn=response['LoadBalancers'][0]['LoadBalancerArn'],
Attributes=[
{
'Key': 'access_logs.s3.enabled',
'Value': 'true'
},
{
'Key': 'access_logs.s3.bucket',
'Value': 'your-bucket-name'
},
{
'Key': 'access_logs.s3.prefix',
'Value': 'your-prefix'
}
]
)
print("Access logging has been enabled for the load balancer")
In the above code snippet, replace your-bucket-name and your-prefix with the S3 bucket name and prefix where you want to store the access logs.
- Finally, we need to verify if access logging is enabled for the load balancer. We can use the same code snippet as in step 1 for this.
# Check if access logging is enabled for the load balancer
response = elb_client.describe_load_balancers(Names=[load_balancer_name])
if response['LoadBalancers'][0]['AccessLogs']['Enabled']:
print("Access logging is now enabled for the load balancer")
else:
print("Access logging could not be enabled for the load balancer")
By following these steps, we can remediate the misconfiguration “Ensure Access Logging Is Enabled For Elastic Beanstalk Load Balancer” for AWS using Python.
