Rule: ELB Application and Classic Load Balancer Logging Enabled
This rule ensures that ELB application and Classic Load Balancer logging is enabled.
| Rule | ELB application and classic load balancer logging should be enabled |
| Framework | General Data Protection Regulation (GDPR) |
| Severity | ✔ High |
Rule Description:
Enabling logging for Elastic Load Balancer (ELB) application and classic load balancers is necessary to comply with the requirements of the General Data Protection Regulation (GDPR). Logging helps to ensure the security and privacy of user data by providing detailed information about traffic patterns, potential security incidents, and any unauthorized access attempts.
Troubleshooting Steps (if necessary):
- 1.Check if the ELB logging settings are enabled for the load balancer.
- 2.Verify the log file delivery status to the designated S3 bucket.
- 3.Ensure that appropriate permissions are set for accessing the log files in the S3 bucket.
- 4.Validate that the log files are capturing the necessary information (e.g., access logs, error logs, request/response headers).
Necessary Codes (if applicable):
No specific codes are required for this rule/policy, as it involves configuring settings within the AWS Management Console or through CLI commands.
Remediation Steps:
To enable ELB application and classic load balancer logging, follow these step-by-step instructions:
- 1.
Log in to the AWS Management Console.
- 2.
Navigate to the EC2 service.
- 3.
Select "Load Balancers" from the left-hand menu.
- 4.
Choose the desired ELB or classic load balancer from the list.
- 5.
In the "Description" tab, check if the logging is enabled. If not, click on the "Edit" button.
- 6.
Enable "Access Logs" or "Application Logging" based on your load balancer type.
- 7.
Specify the S3 bucket to which the log files will be delivered. Create a new bucket if necessary, ensuring that it follows best practices for naming conventions.
- 8.
Optionally, configure the log file prefix and interval for log rotation.
- 9.
Save the changes and wait for the log files to start appearing in the specified S3 bucket. It may take a few minutes for the logs to appear.
- 10.
Ensure that appropriate permissions are set for accessing the log files in the S3 bucket. This includes allowing the necessary users or processes to read the log files and monitoring data.
- 11.
Regularly review the logs for any suspicious activities, errors, or potential security incidents.
CLI Command for Remediation (if applicable):
The following AWS CLI command can be used to enable logging for ELB application and classic load balancers:
aws elbv2 modify-load-balancer-attributes --load-balancer-arn [LOAD_BALANCER_ARN] --attributes "Key=access_logs.s3.enabled,Value=true" "Key=access_logs.s3.bucket,Value=[BUCKET_NAME]"
Replace
[LOAD_BALANCER_ARN][BUCKET_NAME]Note: The above command is specific to Elastic Load Balancer v2. Adjust the command accordingly for classic load balancers if applicable.
