Rule | S3 bucket logging should be enabled |
Framework | CISA-cyber-essentials |
Severity | ✔ Low |
Rule Description:
S3 bucket logging should be enabled for CISA-cyber-essentials. S3 bucket logging is a security best practice that provides detailed information about the access and activities performed on an S3 bucket. By enabling logging, you can monitor and audit access attempts, identify potential security threats, and meet compliance requirements.
Troubleshooting Steps:
If S3 bucket logging is not enabled for CISA-cyber-essentials, follow the steps below to troubleshoot and enable it:
Verify IAM Permissions: Ensure that you have the necessary IAM permissions to enable logging for the S3 bucket. You should have the
s3:PutBucketLogging
permission for the bucket.Verify Bucket Configuration: Check if the S3 bucket you want to enable logging for already exists. If not, create a new bucket using the AWS Management Console, AWS CLI, or SDKs.
Enable Logging: Once you have the required permissions and the bucket is ready, follow the steps below to enable S3 bucket logging:
AWS Management Console:
AWS CLI:
Open a terminal or command prompt.
Run the following AWS CLI command to enable logging for the S3 bucket:
aws s3api put-bucket-logging --bucket CISA-cyber-essentials --bucket-logging-status '{"LoggingEnabled":{"TargetBucket":"<log_bucket_name>","TargetPrefix":"<log_prefix>"}}'
Replace
<log_bucket_name>
with the name of the bucket where you want to store the logs and <log_prefix>
with the desired prefix for the log files.AWS SDKs:
Verify Logging Status: After enabling logging, verify the logging status to ensure it is active. It may take a few minutes for the logs to start appearing in the target bucket.
Remediation Steps:
To enable S3 bucket logging for CISA-cyber-essentials, follow the step-by-step guide below:

Select or create a bucket where the logs will be stored. You can choose the same bucket (CISA-cyber-essentials) or a different bucket for storing the logs.
Optionally, specify a prefix to organize the logs within the target bucket.
Click "Save" to enable logging.
Verify Logging Status:
After enabling logging, go back to the bucket properties and ensure that the logging status is active.
You can also navigate to the target bucket for logging and check if log files are being generated. Keep in mind that it may take a few minutes for the logs to appear.
Summary:
Enabling S3 bucket logging for CISA-cyber-essentials is a crucial security practice to monitor and audit access to your S3 bucket. By following the provided troubleshooting and remediation steps, you can ensure that logging is configured correctly and verify that logs are being generated in the specified target bucket.
