S3 Buckets Should Have Access Logging Enabled
More Info:
AWS S3 Server Access Logging feature should be enabled in order to record access requests useful for security audits. By default, server access logging is not enabled for S3 buckets.

Triage and Remediation
Remediation
Sure, here are the step-by-step instructions to remediate the misconfiguration “S3 Buckets Should Have Access Logging Enabled” in AWS using the AWS console:
- Login to the AWS Management Console.
- Navigate to the S3 service.
- Select the S3 bucket for which you want to enable access logging.
- Click on the “Properties” tab.
- Scroll down to the “Server access logging” section and click on the “Edit” button.
- Select the “Enable logging” checkbox.
- Specify the target bucket where you want to store the access logs.
- Optionally, you can also specify a prefix for the log files.
- Click on the “Save changes” button to enable access logging for the S3 bucket.
Once you have completed these steps, access logging will be enabled for the S3 bucket and all the access logs will be stored in the target bucket that you specified. This will help you to track all the requests made to the S3 bucket and ensure that there are no unauthorized access attempts.
To remediate the misconfiguration of S3 Buckets not having Access Logging enabled in AWS using AWS CLI, follow these steps:
-
Open the AWS CLI on your local machine and ensure that you have the necessary permissions to access the AWS account.
-
Run the following command to enable access logging for the S3 bucket:
aws s3api put-bucket-logging --bucket <bucket-name> --logging-configuration '{"LogBucket": "<bucket-name>", "LogFilePrefix": "<prefix>"}'
Replace
<bucket-name>
with the name of the S3 bucket for which you want to enable access logging.Replace
<prefix>
with the desired prefix for the access log file. -
After running the command, verify that access logging has been enabled for the S3 bucket by running the following command:
aws s3api get-bucket-logging --bucket <bucket-name>
This command should return the access logging configuration for the S3 bucket.
-
Repeat the above steps for all the S3 buckets in the AWS account that do not have access logging enabled.
By following these steps, you can remediate the misconfiguration of S3 Buckets not having Access Logging enabled in AWS using AWS CLI.
To remediate the misconfiguration of S3 buckets not having access logging enabled in AWS using Python, you can follow these steps:
- First, you need to identify the S3 buckets that do not have access logging enabled. You can use the AWS SDK for Python (Boto3) to list all the S3 buckets in your AWS account and check if access logging is enabled for each bucket.
Here is a sample code snippet to list all the S3 buckets and check if access logging is enabled for each bucket:
import boto3
# Create an S3 client
s3 = boto3.client('s3')
# List all the S3 buckets in your AWS account
response = s3.list_buckets()
# Loop through each bucket and check if access logging is enabled
for bucket in response['Buckets']:
bucket_name = bucket['Name']
logging_enabled = False
# Check if access logging is enabled for the bucket
try:
logging = s3.get_bucket_logging(Bucket=bucket_name)
if 'LoggingEnabled' in logging:
logging_enabled = True
except:
pass
# If access logging is not enabled, enable it for the bucket
if not logging_enabled:
s3.put_bucket_logging(
Bucket=bucket_name,
BucketLoggingStatus={
'LoggingEnabled': {
'TargetBucket': bucket_name,
'TargetPrefix': 'access-logs/'
}
}
)
- The above code snippet will enable access logging for all the S3 buckets that do not have it enabled. The access logs will be stored in a folder named
access-logs
in the same bucket.
Note: You need to have the necessary permissions to enable access logging for S3 buckets in your AWS account.
