Ensuring API Gateway Stage Logging is Enabled for SOC 2 Compliance
Overview
Amazon API Gateway is a fully managed service that makes it easier for developers to create, publish, maintain, monitor, and secure APIs. For compliance with Service Organization Control 2 (SOC 2) reporting, it is critical to have detailed logs of activities occurring within your API Gateway stages. Enabling logging helps to meet the monitoring and auditing requirements of SOC 2 by providing an immutable record of API transactions.
Benefits of Enabling Logging
- Monitoring: Track API usage and observe how the APIs are being accessed.
- Auditing: Satisfy compliance by having the ability to audit all transactions.
- Troubleshooting: Quickly identify and resolve issues that may arise in API operations.
- Security: Detect and investigate potential security breaches or unauthorized behavior.
Step-by-step Guide for Remediation
Step 1: Enable CloudWatch Logs for API Gateway
- 1.Log in to the AWS Management Console.
- 2.Navigate to the API Gateway service.
- 3.Select the API for which logging needs to be enabled.
- 4.Go to the "Stages" section in the left panel.
- 5.Select the stage of the API you want to enable logging for.
- 6.Under the "Logs/Tracing" tab, set the "CloudWatch Logs" option to 'Enabled'.
- 7.Choose an appropriate log level (e.g., INFO or ERROR).
- 8.Optionally, set up "Data Trace" and "Log full requests/responses" according to your compliance needs.
Step 2: Ensure IAM Permissions
AWS API Gateway needs the necessary permissions to write logs to CloudWatch. Ensure that the IAM role associated with API Gateway has the following policies attached:
AmazonAPIGatewayPushToCloudWatchLogs
(or a more restrictive custom policy that allowsCloudWatchLogsFullAccess
,logs:CreateLogGroup
, andlogs:CreateLogStream
actions)logs:PutLogEvents
Necessary IAM Policy Example
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"logs:CreateLogGroup",
"logs:CreateLogStream",
"logs:DescribeLogStreams",
"logs:PutLogEvents"
],
"Resource": "*"
}
]
}
Step 3: Adjust Retention Settings (Optional)
By default, CloudWatch Logs are retained indefinitely. To adjust the log retention period:
- 1.Navigate to the CloudWatch service in the AWS Console.
- 2.Click on "Log groups".
- 3.Find the log group corresponding to your API Gateway.
- 4.Select the log group and click on "Retention settings".
- 5.Choose the desired retention period for your compliance needs.
CLI Commands to Enable Logging

- If logs are not appearing, ensure that API Gateway has the required permissions to write to CloudWatch.
- Confirm that the IAM role's trust relationship allows the API Gateway service to assume the role.
- Check the format of log entries to ensure it complies with the necessary data capture for SOC 2 compliance.
- Verify if the log group exists in CloudWatch and the logs are not being written to an unexpected log group.
