Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q48-Q53):

質問 # 48
A company is running its application on AWS. The company has a multi-environment setup, and each environment is isolated in a separate AWS account. The company has an organization in AWS Organizations to manage the accounts. There is a single dedicated security account for the organization. The company must create an inventory of all sensitive data that is stored in Amazon S3 buckets across the organization's accounts. The findings must be visible from a single location.
Which solution will meet these requirements?

正解：D

解説：
Amazon Macie is the AWS service designed specifically to discover, classify, and inventory sensitive data stored in Amazon S3. According to the AWS Certified Security - Specialty Study Guide, Macie can be enabled organization-wide using AWS Organizations, with a delegated administrator account that centrally manages findings across all member accounts.
By designating the security account as the delegated administrator for both Amazon Macie and AWS Security Hub, the company can centralize sensitive data findings in a single location. Macie automatically scans S3 buckets for sensitive data such as personally identifiable information (PII) and publishes findings to Security Hub for centralized visibility and reporting.
Option B and C are incorrect because Amazon Inspector does not scan S3 objects for sensitive data. Option D is invalid because AWS Trusted Advisor does not ingest Macie sensitive data findings.
AWS best practices recommend Amazon Macie with delegated administration and Security Hub integration for centralized sensitive data inventory across multi-account environments.

質問 # 49
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.
Which additional step will meet these requirements?

正解：D

解説：
Amazon S3 pre-signed URLs grant temporary access based on the permissions of the principal that generates them. AWS Certified Security - Specialty documentation explains that fine-grained authorization can be enforced by combining pre-signed URLs with IAM policy conditions.
By tagging each invoice object with a client identifier and adding a condition to the EC2 instance role policy using s3:ResourceTag/ClientId, the role can generate pre-signed URLs only for objects associated with a specific client. This ensures that each client can access only their own invoices, even though the URLs are temporary and unauthenticated.
Option A over-permissions clients. Option C is unnecessary because instance profiles already use temporary credentials. Option D violates AWS best practices by using long-term credentials.
AWS recommends resource tagging with IAM policy conditions for scalable, secure access control.

質問 # 50
A company runs a web application on a fleet of Amazon EC2 instances that are in an Auto Scaling group. The EC2 instances are in the same VPC subnet as other workloads.
A security engineer deploys Amazon GuardDuty and integrates it with AWS Security Hub. The security engineer needs to implement an automated solution to detect and respond to anomalous traffic patterns. The solution must follow AWS best practices for initial incident response and must minimize disruption to the web application.
Which solution will meet these requirements?

正解：A

解説：
AWS incident response best practices emphasize containment with minimal blast radius while preserving business continuity. According to the AWS Certified Security - Specialty Official Study Guide, isolating a compromised resource while allowing the application to continue operating is the recommended initial response.
By creating an Amazon EventBridge rule that reacts to GuardDuty anomalous traffic findings and invokes an AWS Lambda function, the security engineer can automatically remove the affected EC2 instance from the Auto Scaling group and attach a restricted security group. This immediately stops malicious activity while allowing Auto Scaling to replace the instance and keep the application available.


質問 # 51
A company's application team needs a new AWS Key Management Service (AWS KMS) customer managed key to use with Amazon S3. The company's security policy requires separate keys for different AWS services to limit security exposure. How can a security engineer limit the KMS customer managed key to work with only Amazon S3?

正解：C

解説：
AWS KMS provides condition keys that can be used to tightly scope how and where a customer managed key can be used. According to the AWS Certified Security - Specialty Study Guide, the kms:ViaService condition key is specifically designed to restrict key usage to requests that originate from a particular AWS service in a specific Region.
By configuring the key policy to allow KMS cryptographic operations only when kms:ViaService equals s3.<region>.amazonaws.com, the security engineer ensures that the key can be used exclusively by Amazon S3. Even if other IAM principals have permissions to use the key, the key cannot be used by other services such as Amazon EC2, Amazon RDS, or AWS Lambda.
Option A is incorrect because AWS services do not assume identities in key policies. Options C and D modify IAM role policies, which do not control how a KMS key is used by AWS services.
AWS documentation clearly states that service-level restrictions must be enforced at the KMS key policy level using condition keys.
This approach enforces strong separation of duties and limits blast radius, which aligns with AWS security best practices.


質問 # 52
An IAM user receives an Access Denied message when the user attempts to access objects in an Amazon S3 bucket. The user and the S3 bucket are in the same AWS account. The S3 bucket is configured to use server-side encryption with AWS KMS keys (SSE-KMS) to encrypt all of its objects at rest by using a customer managed key from the same AWS account. The S3 bucket has no bucket policy defined. The IAM user has been granted permissions through an IAM policy that allows thekms:Decryptpermission to the customer managed key. The IAM policy also allows thes3:List* ands3:Get* permissions for the S3 bucket and its objects.
Which of the following is a possible reason that the IAM user cannot access the objects in the S3 bucket?

正解：A

解説：
WithSSE-KMS, authorization is a two-part check: the caller must have S3 permissions to read the objectandthe caller must be allowed to use the KMS key for decryption. Even if an IAM policy grants kms:Decrypt, the request will still fail if theKMS key policydoes not allow the principal (or does not allow the account to delegate use of the key). KMS key policies are authoritative: they can prevent key usage even when IAM policies appear to allow it.
A common misconfiguration is editing the key policy and removing the statement that grants the AWS account (or key administrators) the ability to manage and delegate permissions for the key-- often described as removing "Enable IAM user permissions" or otherwise blocking the account from using IAM policies to authorize key usage. In that case, the IAM user's kms:Decrypt permission in IAM is not sufficient because the key policy no longer permits it, resulting in Access Denied when S3 attempts to call KMS on the user's behalf during GetObject.
