Question 67 of 100 | ← Chapter 15

Q1167. A company's solutions architect wants to receive an email alert whenever Amazon GuardDuty,AWS Identity and Access Management Access Analyzer, or Amazon Macie generate a high-severity security finding. The company uses AWS Control Tower to govern all of its accounts. The company also uses AWS Security Hub with all of the AWS service integrations turned on.Which solution will meet these requirements with the LEAST operational overhead?

• A. Set up separate AWS Lambda functions for GuardDuty, IAM Access Analyzer,and Macie to call each service's public APl to retrieve high-severity findings. Use Amazon Simple Notification Service (Amazon SNS) to send the email alerts. Create an Amazon EventBridge rule to invoke the functions on a schedule.
• B. Create an Amazon EventBridge rule with a pattern that matches Security Hub findings events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic. ✓
• C. Create an Amazon EventBridge rule with a pattern that matches AWS Control Tower events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic.Subscribe the desired email addresses to the SNS topic.
• D. Host an application on Amazon EC2 to call the GuardDuty,IAM Access Analyzer, and Macie APls.Within the application, use the Amazon Simple Notification Service (Amazon SNS) API to retrieve high- severity findings and to send the findings to an SNS topic. Subscribe the desired email addresses to the SNS topic.

Correct Answer: B. Create an Amazon EventBridge rule with a pattern that matches Security Hub findings events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic.

Explanation

To meet the company's requirements of receiving email alerts for high-severity security findings from Amazon GuardDuty, AWS IAM Access Analyzer, and Amazon Macie with the least operational overhead, the best solution is:Correct Answer:BB. Create an Amazon EventBridge rule with a pattern that matches Security Hub findings events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic.Explanation:AWS Security Hub Integration:Security Hub aggregates findings from multiple AWS security services (including GuardDuty, IAM Access Analyzer, and Macie) into a single dashboard.When enabled, these services automatically send their findings to Security Hub.Amazon EventBridge for Security Hub Findings:EventBridge can monitor Security Hub findings events.You can create an EventBridge rule with a pattern that matches high-severity findings (e.g., severityRating:HIGH).The rule can trigger an SNS notification when a high-severity finding is detected.Amazon SNS for Email Alerts:SNS can send email alerts to subscribed recipients when triggered by the EventBridge rule. No custom code or Lambda functions are needed--this is a serverless, managed solution.Why Other Options Are Incorrect:A. Set up separate AWS Lambda functions for GuardDuty, IAM Access Analyzer, and Macie to call each service's public API to retrieve high-severity findings. Use Amazon Simple Notification Service (Amazon SNS) to send the email alerts. Create an Amazon EventBridge rule to invoke the functions on a schedule. This approach requires custom Lambda functions and polling (via scheduled EventBridge rules), which increases operational overhead.Security Hub already aggregates findings, so polling individual services is unnecessary and inefficient. C. Create an Amazon EventBridge rule with a pattern that matches AWS Control Tower events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic. AWS Control Tower is for governance and account management, not for security findings. Control Tower does not generate security findings from GuardDuty, IAM Access Analyzer, or Macie. D. Host an application on Amazon EC2 to call the GuardDuty, IAM Access Analyzer, and Macie APIs. Within the application, use the Amazon Simple Notification Service (Amazon SNS) API to retrieve high- severity findings and to send the findings to an SNS topic. Subscribe the desired email addresses to the SNS topic.This requires running and maintaining an EC2 instance, which increases operational overhead. It is unnecessary because Security Hub and EventBridge can handle this without custom infrastructure.Key Takeaways:Security Hub aggregates findings from GuardDuty, IAM Access Analyzer, and Macie, simplifying monitoring.EventBridge + SNS is a serverless, managed solution for triggering alerts based on Security Hub findings. Other options require custom code, polling, or misuse of AWS services (like Control Tower), increasing operational overhead.Final Answer:B. Create an Amazon EventBridge rule with a pattern that matches Security Hub findings events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic.
