Which strategies should the Solutions Architect use?
Use Amazon CloudWatch Logs with CloudWatch filters to identify remote IP addresses. Use CloudWatch Events rules with AWS Lambda to automatically remediate S3 bucket policy changes. Use Amazon SES with CloudWatch Events rules for alerts.
Use Amazon Athena with S3 access logs to identify remote IP addresses. Use AWS Config rules with AWS Systems Manager Automation to automatically remediate S3 bucket policy changes. Use Amazon SNS with AWS Config rules for alerts.
Use S3 access logs with Amazon Elasticsearch Service and Kibana to identify remote IP addresses. Use an Amazon Inspector assessment template to automatically remediate S3 bucket policy changes. Use Amazon SNS for alerts.
Use Amazon Macie with an S3 bucket to identify access patterns and remote IP addresses. Use AWS Lambda with Macie to automatically remediate S3 bucket policy changes. Use Macie automatic alerting capabilities for alerts.
Explanations:
Amazon CloudWatch Logs do not directly provide the capability to identify IP addresses accessing S3 buckets; they are primarily for monitoring and logging AWS resources. While CloudWatch Events and AWS Lambda can remediate policy changes and send alerts, they do not inherently tie into S3 access logs for direct IP identification.
Amazon Athena can query S3 access logs to extract remote IP addresses accessing bucket objects. AWS Config can monitor and enforce compliance on bucket policies, and it can trigger AWS Systems Manager Automation to remediate any policy changes. Amazon SNS can be configured to send alerts based on AWS Config rules for policy changes.
While S3 access logs can be analyzed with Amazon Elasticsearch Service and Kibana for IP identification, Amazon Inspector is not used for remediating S3 bucket policy changes. Additionally, alerts would need a separate setup, as SNS is not inherently tied to Elasticsearch.
Amazon Macie primarily focuses on data security and privacy by detecting sensitive data; it is not typically used for identifying remote IP addresses accessing S3 objects. While it has capabilities for alerting and can trigger actions, it doesn’t directly remediate policy changes or provide the full scope of monitoring required for this scenario.
I rate that the answer is:
Use Amazon Athena with S3 access logs to identify remote IP addresses. Use AWS Config rules with AWS Systems Manager Automation to automatically remediate S3 bucket policy changes. Use Amazon SNS with AWS Config rules for alerts.
