AWS Certified Security – Specialty (SCS-C02) — Question 87

A company needs to improve its ability to identify and prevent IAM policies that grant public access or cross-account access to resources. The company has implemented AWS Organizations and has started using AWS Identity and Access Management Access Analyzer to refine overly broad access to accounts in the organization.

A security engineer must automate a response in the company's organization for any newly created policies that are overly permissive. The automation must remediate external access and must notify the company's security team.

Which combination of steps should the security engineer take to meet these requirements? (Choose three.)

Answer options

• A. Create an AWS Step Functions state machine that checks the resource type in the finding and adds an explicit Deny statement in the trust policy for the IAM role. Configure the state machine to publish a notification to an Amazon Simple Notification Service (Amazon SNS) topic.
• B. Create an AWS Batch job that forwards any resource type findings to an AWS Lambda function. Configure the Lambda function to add an explicit Deny statement in the trust policy for the IAM role. Configure the AWS Batch job to publish a notification to an Amazon Simple Notification Service (Amazon SNS) topic.
• C. In Amazon EventBridge, create an event rule that matches active IAM Access Analyzer findings and invokes AWS Step Functions for resolution.
• D. In Amazon CloudWatch, create a metric filter that matches active IAM Access Analyzer findings and invokes AWS Batch for resolution.
• E. Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure the queue to forward a notification to the security team that an external principal has been granted access to the specific IAM role and has been blocked.
• F. Create an Amazon Simple Notification Service (Amazon SNS) topic for external or cross-account access notices. Subscribe the security team's email addresses to the topic.

Correct answer: A, C, F

Explanation

The correct steps involve creating an AWS Step Functions state machine to handle findings, using EventBridge to trigger the resolution process, and setting up an SNS topic for notifications to the security team. Options B and D do not directly address the automation of overly permissive policies, while options E and F do not encompass the necessary remediation processes.
