AWS Certified Security – Specialty (SCS-C02) — Question 179

A company has secured the AWS account root user for its AWS account by following AWS best practices. The company also has enabled AWS CloudTrail, which is sending its logs to Amazon S3. A security engineer wants to receive notification in near-real time if a user uses the AWS account root user credentials to sign in to the AWS Management Console

Which solutions will provide this notification? (Choose two.)

Answer options

• A. Use AWS Trusted Advisor and its security evaluations for the root account. Configure an Amazon EventBridge event rule that is invoked by the Trusted Advisor API. Configure the rule to target an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe any required endpoints to the SNS topic so that these endpoints can receive notification.
• B. Use AWS IAM Access Analyzer. Create an Amazon Cloud Watch Logs metric filter to evaluate log entries from Access Analyzer that detect a successful root account login. Create an Amazon CloudWatch alarm that monitors whether a root login has occurred. Configure the CloudWatch alarm to notify an Amazon Simple Notification Service (Amazon SNS) topic when the alarm enters the ALARM state. Subscribe any required endpoints to this SNS topic so that these endpoints can receive notification.
• C. Configure AWS CloudTrail to send its logs to Amazon CloudWatch Logs. Configure a metric filter on the CloudWatch Logs log group used by CloudTrail to evaluate log entries for successful root account logins. Create an Amazon CloudWatch alarm that monitors whether a root login has occurred. Configure the CloudWatch alarm to notify an Amazon Simple Notification Service (Amazon SNS) topic when the alarm enters the ALARM state. Subscribe any required endpoints to this SNS topic so that these endpoints can receive notification.
• D. Configure AWS CloudTrail to send log notifications to an Amazon Simple Notification Service (Amazon SNS) topic. Create an AWS Lambda function that parses the CloudTrail notification for root login activity and notifies a separate SNS topic that contains the endpoints that should receive notification. Subscribe the Lambda function to the SNS topic that is receiving log notifications from CloudTrail.
• E. Configure an Amazon EventBridge event rule that runs when Amazon CloudWatch API calls are recorded for a successful root login. Configure the rule to target an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe any required endpoints to the SNS topic so that these endpoints can receive notification.

Correct answer: C, E

Explanation

The correct answers, C and E, utilize AWS CloudTrail and Amazon CloudWatch to effectively monitor and alert on root account logins. Option C sets up a system to filter CloudTrail logs for root logins and trigger an alarm, while option E creates an EventBridge rule to detect successful logins. Options A, B, and D do not directly monitor CloudTrail logs for root logins in the same efficient manner.
