AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 16

A company manages a set of accounts on AWS by using AWS Organizations. The company's security team wants to use a native AWS service to regularly scan all AWS accounts against the Center for Internet Security (CIS) AWS Foundations Benchmark.
What is the MOST operationally efficient way to meet these requirements?

Answer options

• A. Designate a central security account as the AWS Security Hub administrator account. Create a script that sends an invitation from the Security Hub administrator account and accepts the invitation from the member account. Run the script every time a new account is created. Configure Security Hub to run the CIS AWS Foundations Benchmark scans.
• B. Run the CIS AWS Foundations Benchmark across all accounts by using Amazon Inspector.
• C. Designate a central security account as the Amazon GuardDuty administrator account. Create a script that sends an invitation from the GuardDuty administrator account and accepts the invitation from the member account. Run the script every time a new account is created. Configure GuardDuty to run the CIS AWS Foundations Benchmark scans.
• D. Designate an AWS Security Hub administrator account. Configure new accounts in the organization to automatically become member accounts. Enable CIS AWS Foundations Benchmark scans.

Correct answer: D

Explanation

The correct answer is D because it allows for automatic integration of new accounts into the AWS Security Hub, simplifying the management of CIS AWS Foundations Benchmark scans. Option A requires manual scripting for each new account, which is less efficient. Option B uses Amazon Inspector, which is not specifically designed for this benchmark scanning task. Option C involves GuardDuty, which does not perform the CIS AWS Foundations Benchmark scans as intended.
