Exam question from Amazon's AWS Certified Solutions Architect - Professional

Question #: 970
Topic #: 1

[All AWS Certified Solutions Architect - Professional Questions]

A company uses Amazon EC2 instances to run business-critical applications. Software that is running on the EC2 instances recently caused Amazon GuardDuty to generate the PenTest:S3/KaliLinux finding for some of the company's environments. The company wants to prevent this software from running again. The company is using AWS Organizations to manage its AWS accounts.

What should a solutions architect do to meet these requirements?

A. Configure Amazon Inspector to check the EC2 instances for the forbidden software and to send an Amazon Simple Notification Service (Amazon SNS) notification when the software is identified. Create an AWS Lambda function that stops the EC2 instances and notifies the company. Subscribe the Lambda function to the SNS topic.
B. Create a centralized Amazon EventBridge (Amazon CloudWatch Events) bus to receive GuardDuty events from all accounts. Configure an EventBridge (CloudWatch Events) rule to invoke an AWS Lambda function when the GuardDuty event is generated. Configure the Lambda function to stop the EC2 instances and notify the company.
C. Configure an SCP to prevent the software from being installed. Apply the SCP to the root OU for the organization.
D. Create a library of approved EC2 AMIs. Create a catalog in AWS Service Catalog to deploy the AMIs for the organization. Update IAM policies to allow EC2 instances to be created only with Service Catalog AMIs.

Selected Answer: D

Kali Linux is an OS. They want to prevent the usage of Kali Linux. https://docs.aws.amazon.com/guardduty/latest/ug/guardduty_finding-types-s3.html#pentest-s3-kalilinux A - Inpector is for vulnerabilities of installed software B - this is possible but reactive, it can take 5 minutes for GuardDuty to send the EventBridge notification. https://docs.aws.amazon.com/guardduty/latest/ug/guardduty_findings_cloudwatch.html#guardduty_findings_cloudwatch_notification_frequency D - prevents unapproved AMIs = OS from being launched. My only concern is that it says IAM policies but should be SCP for orgs.

Both A & B seems to be reactive and only stops the EC2 instance. D seems to be a permanent resolution. Any thoughts any one?

I think B is better than D, because it prevents the development of the application

Selected Answer: A

It's A: Q: What is the format of GuardDuty findings? GuardDuty findings come in a common JavaScript Object Notation (JSON) format, which is also used by Macie and Amazon Inspector. This makes it easier for customers and partners to consume security findings from all three services and incorporate them into broader event management, workflow, or security solutions. https://aws.amazon.com/guardduty/faqs/

Selected Answer: B

It is B and not A as we should intercept the security events already generated by Guard Duty(B) and not invent some custom stuff ignoring the events(A).
