Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q74-Q79):

質問 # 74
A company is expanding its group of stores. On the day that each new store opens, the company wants to launch a customized web application for that store. Each store's application will have a non-production environment and a production environment. Each environment will be deployed in a separate AWS account.
The company uses AWS Organizations and has an OU that is used only for these accounts.
The company distributes most of the development work to third-party development teams. A security engineer needs to ensure that each team follows the company's deployment plan for AWS resources. The security engineer also must limit access to the deployment plan to only the developers who need access. The security engineer already has created an AWS CloudFormation template that implements the deployment plan.
What should the security engineer do next to meet the requirements in theMOST secureway?

A. Create an AWS Service Catalog portfolio in the organization's management account. Upload the CloudFormation template. Add the template to the portfolio's product list. Create an IAM role that has a trust policy that allows cross-account access to the portfolio for users in the OU accounts. Attach the AWSServiceCatalogEndUserFullAccess managed policy to the role.
B. Create an AWS Service Catalog portfolio in the organization's management account. Upload the CloudFormation template. Add the template to the portfolio's product list. Share the portfolio with the OU.
C. Use the CloudFormation CLI to create a module from the CloudFormation template. Register the module as a private extension in the CloudFormation registry. Publish the extension. Share the extension with the OU.
D. Use the CloudFormation CLI to create a module from the CloudFormation template. Register the module as a private extension in the CloudFormation registry. Publish the extension. In the OU, create an SCP that allows access to the extension.

正解：B

解説：
AWS Service Catalog is designed to allow organizations to create and manageapproved sets of CloudFormation templates, known as products, and make them available to specific accounts or organizational units (OUs). According to the AWS Certified Security - Specialty Study Guide, Service Catalog is thepreferred governance mechanismfor enforcing standardized infrastructure deployments while maintaining strong access controls.
By creating a Service Catalog portfolio in the management account and sharing it with a specific OU, the security engineer ensures that only accounts within that OU can deploy the approved CloudFormation template. This guarantees that third-party developers can deploy infrastructureonly in accordance with the company's predefined deployment plan, without modifying or directly accessing the template itself.
Option B and D use CloudFormation modules, which are intended for reusable resource definitions but do not provide the same level ofdeployment governance, access control, and lifecycle managementas Service Catalog. Option C introduces unnecessary cross-account IAM roles, increasing the attack surface and operational complexity, which violates the "most secure" requirement.
AWS documentation explicitly states thatService Catalog is the recommended service for distributing standardized CloudFormation templates across AWS Organizations, while controlling who can deploy them and where.

質問 # 75
A company's security engineer receives an abuse notification from AWS. The notification indicates that someone is hosting malware from the company's AWS account. After investigation, the security engineer finds a new Amazon S3 bucket that an IAM user created without authorization. Which combination of steps should the security engineer take to MINIMIZE the consequences of this compromise? (Select THREE.)

A. Encrypt all AWS CloudTrail logs.
B. Rotate or delete all AWS access keys.
C. Change the password for all IAM users.
D. Turn on Amazon GuardDuty.
E. Take snapshots of all Amazon Elastic Block Store (Amazon EBS) volumes.
F. Delete any resources that are unrecognized or unauthorized.

正解：B、D、F

解説：
AWS incident response best practices emphasize rapid containment, credential revocation, and threat detection to minimize the blast radius of a compromise. According to the AWS Certified Security - Specialty Official Study Guide, when unauthorized resources such as an Amazon S3 bucket hosting malware are discovered, immediate action must be taken to stop further misuse of the account and to prevent recurrence.
Rotating or deleting all AWS access keys (Option D) is a critical containment step. If an IAM user has been compromised, any long-term credentials associated with that user must be revoked immediately to prevent continued unauthorized access. AWS guidance explicitly lists access key rotation or deletion as a first-response action for suspected credential compromise.
Deleting unrecognized or unauthorized resources (Option F) directly removes the malicious infrastructure that is being abused. In this case, deleting the unauthorized S3 bucket immediately stops malware distribution and reduces reputational and compliance impact.
Turning on Amazon GuardDuty (Option B) enables continuous threat detection by analyzing CloudTrail events, VPC Flow Logs, and DNS logs. GuardDuty can identify additional malicious activity, compromised credentials, or persistence mechanisms that the attacker may have established. AWS documentation recommends enabling GuardDuty during or immediately after an incident to detect ongoing or future threats.

質問 # 76
A company must immediately disable compromised IAM users across all AWS accounts and collect all actions performed by the user in the last 7 days.
Which solution will meet these requirements?

A. Remove IAM policies and query logs in Security Hub.
B. Remove permission sets and query logs using CloudWatch Logs Insights.
C. Disable the IAM user and query CloudTrail logs in Amazon S3 using Athena.
D. Disable the user in IAM Identity Center and query the organizational event data store.

正解：D

解説：
AWS IAM Identity Center centrally manages user access across an AWS Organization. Disabling the user in Identity Center immediately revokes access to all AWS accounts. According to AWS Certified Security - Specialty documentation, organizational CloudTrail event data stores provide centralized, queryable access to all events across accounts.
Using CloudTrail Lake enables direct querying of activity without exporting logs. Disabling the user at the Identity Center level ensures full containment.

質問 # 77
A company has an organization in AWS Organizations. The organization consists of multiple OUs. The company must prevent IAM principals from outside the organization from accessing the organization's Amazon S3 buckets. The solution must not affect the existing access that the OUs have to the S3 buckets. Which solution will meet these requirements?

A. Deploy an SCP that includes the "aws:ResourceOrgID": "${aws:PrincipalOrgID}" condition.
B. Configure S3 Block Public Access for all AWS accounts.
C. Deploy an SCP that includes the "aws:ResourceOrgPaths": "${aws:PrincipalOrgPaths}" condition.
D. Configure S3 Block Public Access for all S3 buckets.

正解：A

解説：
By using an SCP with the aws:ResourceOrgID and aws:PrincipalOrgID condition, you ensure that only IAM principals from within the same AWS Organization can access the S3 buckets. This SCP restricts access from any IAM principals outside the organization while allowing access within the organization. This approach meets the requirement without affecting existing permissions within the OUs.

質問 # 78
A company runs a web application on a fleet of Amazon EC2 instances in an Auto Scaling group. Amazon GuardDuty and AWS Security Hub are enabled. The security engineer needs an automated response to anomalous traffic that follows AWS best practices and minimizes application disruption.
Which solution will meet these requirements?

A. Use EventBridge to invoke a Lambda function that removes the affected instance from the Auto Scaling group and isolates it with a restricted security group.
B. Use EventBridge to disable the instance profile access keys.
C. Send GuardDuty findings to Amazon SNS for email notification.
D. Use Security Hub to update the subnet network ACL to block traffic.

正解：A

解説：
AWS incident response best practices emphasize isolating compromised resources rather than immediately terminating them. According to AWS Certified Security - Specialty documentation, removing an instance from an Auto Scaling group prevents replacement loops, while applying a restrictive security group isolates the instance for forensic analysis.
Using Amazon EventBridge to trigger an AWS Lambda function enables automated, consistent responses to GuardDuty findings. This approach minimizes disruption to the application because healthy instances continue serving traffic while the affected instance is isolated.
Disabling credentials or modifying network ACLs can have broader impact on unrelated workloads. SNS notifications alone do not provide response automation.
AWS recommends isolate-and-investigate patterns for EC2 incident response.
