Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q223-Q228):

質問 # 223
A company is running an application in the eu-west-1 Region. The application uses an AWS Key Management Service (AWS KMS) customer managed key to encrypt sensitive data. The company plans to deploy the application in the eu-north-1 Region. A security engineer needs to implement a key management solution for the application deployment in the new Region. The security engineer must minimize changes to the application code. Which change should the security engineer make to the AWS KMS configuration to meet these requirements?

A. Allocate a new customer managed key to eu-north-1. Create an alias for eu--1. Change the application code to point to the alias for eu--1.
B. Allocate a new customer managed key to eu-north-1. Create the same alias name for both keys.
Configure the application deployment to use the key alias.
C. Allocate a new customer managed key to eu-north-1 to be used by the application that is deployed in that Region.
D. Update the key policies in eu-west-1. Point the application in eu-north-1 to use the same customer managed key as the application in eu-west-1.

正解：B

解説：
AWS KMS keys are regional resources and cannot be used across Regions. According to AWS Certified Security - Specialty documentation, applications that are deployed in multiple Regions should use region-specific customer managed keys while referencing keys by alias instead of key ID.
By creating a new customer managed key in eu-north-1 and assigning it the same alias as the key in eu-west-1, the application code can continue to reference the alias without modification.
Each Region resolves the alias to the correct local key, ensuring encryption continues to function correctly.
Option A is invalid because KMS keys are regional. Option B requires application changes.
Option D introduces unsupported alias patterns.
AWS best practices recommend alias-based key references for multi-Region deployments.

質問 # 224
A company uses several AWS CloudFormation stacks to handle the deployment of a suite of applications. The leader of the company's application development team notices that the stack deployments fail with permission errors when some team members try to deploy the stacks.
However, other team members can deploy the stacks successfully.
The team members access the account by assuming a role that has a specific set of permissions.
All team members have permissions to perform operations on the stacks.
Which combination of steps will ensure consistent deployment of the stacks MOST securely?
(Select THREE.)

A. Create a service role that has a composite principal that contains each service that needs the necessary permissions.
B. Update each stack to use the service role.
C. Create a service role that has cloudformation.amazonaws.com as the service principal.
D. Add policies that reference the ARNs of each AWS service that requires permissions.
E. Add a policy to each member role to allow the iam:PassRole action for the service role.
F. Add policies that reference each CloudFormation stack ARN.

正解：B、C、E

解説：
AWS CloudFormation supports the use of a service role, which allows CloudFormation to assume a dedicated IAM role to create and manage resources on behalf of users. According to the AWS Certified Security - Specialty Study Guide, using a service role is the most secure and consistent way to ensure predictable stack deployments when users have varying permission sets.
By creating a service role with cloudformation.amazonaws.com as the trusted service principal (Option B), CloudFormation--not individual users--assumes responsibility for resource creation.
Updating each stack to explicitly use this service role (Option E) ensures that all deployments use the same permission set, eliminating inconsistencies.
Granting the team members permission to pass the service role via iam:PassRole (Option F) is required so that CloudFormation can assume the role during stack operations. This approach adheres to the principle of least privilege and prevents users from gaining direct access to elevated permissions.

質問 # 225
A company has several Amazon S3 buckets that do not enforce encryption in transit. A security engineer must implement a solution that enforces encryption in transit for all the company's existing and future S3 buckets.
Which solution will meet these requirements?

A. Create an AWS CloudTrail trail. Enable S3 data events on the trail. Create an AWS Lambda function that applies a bucket policy to deny requests when the value of the aws:SecureTransport condition key is False. Configure the CloudTrail trail to invoke the Lambda function.
B. Enable Amazon Inspector. Create a custom AWS Lambda rule. Create a Lambda function that applies a bucket policy to deny requests when the value of the aws:SecureTransport condition key is False. Set the Lambda function as the target of the rule.
C. Enable AWS Config. Configure the s3-bucket-ssl-requests-only AWS Config managed rule and set the rule trigger type to Hybrid. Create an AWS Systems Manager Automation runbook that applies a bucket policy to deny requests when the value of the aws:SecureTransport condition key is False.
Configure automatic remediation. Set the runbook as the target of the rule.
D. Enable AWS Config. Create a proactive AWS Config Custom Policy rule. Create a Guard clause to evaluate the S3 bucket policies to check for a value of True for the aws:SecureTransport condition key.
If the AWS Config rule evaluates to NON_COMPLIANT, block resource creation.

正解：C

解説：
To enforce encryption in transit for Amazon S3, AWS best practice is to require HTTPS (TLS) by using a bucket policy condition that denies any request where aws:SecureTransport is false. The requirement includes both existing buckets and future buckets, so the control must continuously evaluate configuration drift and automatically remediate. AWS Config is the service intended for continuous configuration compliance monitoring across resources, and AWS Config managed rules provide standardized checks with low operational overhead. The s3-bucket-ssl-requests-only managed rule evaluates whether S3 buckets enforce SSL-only requests, aligning directly with enforcing encryption in transit. Setting the trigger type to Hybrid ensures evaluation both on configuration changes and periodically. Automatic remediation with an AWS Systems Manager Automation runbook allows the organization to apply or correct the bucket policy consistently at scale without manual work. This approach also supports governance by maintaining a measurable compliance status while actively fixing noncompliance. Option A is not the best fit because a
"proactive" custom policy rule does not by itself remediate existing buckets and "block resource creation" is not how AWS Config enforces controls. Option C is incorrect because Amazon Inspector is a vulnerability management service and does not govern S3 bucket transport policies. Option D is inefficient and indirect because CloudTrail data events are not a compliance engine and would require custom processing.

質問 # 226
A company runs a global ecommerce website using Amazon CloudFront. The company must block traffic from specific countries to comply with data regulations. Which solution will meet these requirements MOST cost-effectively?

A. Use AWS WAF geo match rules.
B. Use CloudFront geo restriction to deny the countries.
C. Use geolocation headers in CloudFront.
D. Use AWS WAF IP match rules.

正解：B

解説：
Amazon CloudFront includes a built-in geo restriction feature that allows content to be allowed or denied based on the viewer's country. According to AWS Certified Security - Specialty documentation, CloudFront geo restriction is the most cost-effective method for country-based blocking because it does not require AWS WAF or additional rule processing.
AWS WAF geo match rules incur additional cost and are more appropriate when advanced inspection or layered security controls are required. IP-based blocking is impractical due to frequent IP changes. Geolocation headers do not enforce access control.
CloudFront geo restriction is evaluated at the edge and efficiently blocks disallowed countries with minimal latency and cost.

質問 # 227
A company runs an application on an Amazon EC2 instance. The application generates invoices and stores them in an Amazon S3 bucket. The instance profile that is attached to the instance has appropriate access to the S3 bucket.
The company needs to share each invoice with multiple clients that do not have AWS credentials.
Each client must be able to download only the client's own invoices. Clients must download their invoices within 1 hour of invoice creation. Clients must use only temporary credentials to access the company's AWS resources.
A security engineer creates a script that runs on the EC2 instance. The script uses the instance profile to generate an S3 presigned URL for the clients. Each presigned URL expires after 1 hour.
Which additional step will meet these requirements?

A. Update the S3 bucket policy to ensure that clients that use presigned URLs have the S3:Get* permission and the S3:List* permission to access S3 objects in the bucket.
B. Add a StringEquals condition to the IAM role policy for the EC2 instance profile. Configure the policy condition to restrict access based on the s3:ResourceTag/ClientId tag of each invoice. Tag each generated invoice with the ID of its corresponding client.
C. Generate an access key and a secret key for an IAM user that has S3:GetObject permissions on the S3 bucket. Embed the keys into the script. Use the keys to generate the presigned URLs.
D. Update the script to use AWS Security Token Service (AWS STS) to obtain new credentials each time the script runs by assuming a new role that has S3 GetObject permissions. Use the credentials to generate the presigned URLs.

正解：D

解説：
Using AWS Security Token Service to assume a role and generate temporary credentials ensures that access is based on short-lived, ephemeral security credentials rather than long-term credentials. These temporary credentials are then used to create presigned URLs that expire after 1 hour, satisfying both the requirement for time-limited access and the mandate that clients interact only through temporary credentials when accessing the company's AWS resources.
