Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q118-Q123):

質問 # 118
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?

A. The KMS key policy has been edited to remove the ability for the AWS account to have full access to the key.
B. An S3 bucket policy needs to be added to allow the IAM user to access the objects.
C. The IAM policy needs to allow thekms:DescribeKeypermission.
D. The S3 bucket has been changed to use the AWS managed key to encrypt objects at rest.

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.
Option A is not required for decrypting data (DescribeKey is useful for discovery but not necessary for GetObject). Option B would not inherently cause access denied if permissions align. Option C is incorrect because same-account S3 access can be granted purely via IAM without a bucket policy. Therefore, the key policy change is a valid reason.

質問 # 119
A company has an encrypted Amazon Aurora DB cluster in the us-east-1 Region that uses an AWS KMS customer managed key. The company must copy a DB snapshot to the us-west-1 Region but cannot access the encryption key across Regions.
What should the company do to properly encrypt the snapshot in us-west-1?

A. Store the customer managed key in AWS Secrets Manager in us-west-1.
B. Create an IAM policy to allow access to the key in us-east-1 from us-west-1.
C. Create an IAM policy that allows RDS in us-west-1 to access the key in us-east-1.
D. Create a new customer managed key in us-west-1 and use it to encrypt the snapshot.

正解：D

解説：
AWS KMS keys are strictly regional resources. According to AWS Certified Security - Specialty documentation, a KMS key created in one Region cannot be used to encrypt or decrypt data in another Region. This includes encrypted RDS and Aurora snapshots.
When copying an encrypted snapshot to a different Region, the destination Region must have its own KMS key. AWS automatically re-encrypts the snapshot using the specified KMS key in the destination Region during the copy operation.
Options C and D are invalid because IAM policies cannot extend a KMS key's scope across Regions. Option A is incorrect because Secrets Manager does not store or manage KMS keys themselves.
AWS best practices require creating a new customer managed key in the target Region and using it during the snapshot copy process.

質問 # 120
A security team manages a company's AWS Key Management Service (AWS KMS) customer managed keys.
Only members of the security team can administer the KMS keys. The company's application team has a software process that needs temporary access to the keys occasionally. The security team needs to provide the application team's software process with access to the keys.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a key grant to allow the application team to use the KMS keys. Revoke the grant when the application team no longer needs access.
B. Create a new KMS key by generating key material on premises. Import the key material to AWS KMS whenever the application team needs access. Grant the application team permissions to use the key.
C. এক্সপোর্ট the KMS key material to an on-premises hardware security module (HSM). Give the application team access to the key material.
D. Edit the key policy that grants the security team access to the KMS keys by adding the application team as principals. Revert this change when the application team no longer needs access.

正解：A

解説：
AWS KMS key grants are specifically designed to provide temporary, granular permissions to use customer managed keys without modifying key policies. According to the AWS Certified Security - Specialty Study Guide, grants are the preferred mechanism for delegating key usage permissions to AWS principals for short- term or programmatic access scenarios. Grants allow permissions such as Encrypt, Decrypt, or GenerateDataKey and can be created and revoked dynamically.
Using a key grant avoids the operational risk and overhead of editing key policies, which are long-term control mechanisms and should remain stable. AWS documentation emphasizes that frequent key policy changes increase the risk of misconfiguration and accidental privilege escalation. Grants can be revoked immediately when access is no longer required, ensuring strong adherence to the principle of least privilege.
Options A and D violate AWS security best practices because AWS KMS does not allow direct export of key material unless the key was explicitly created as an importable key, and exporting key material increases exposure risk. Option B requires manual policy changes and rollback, which introduces operational overhead and audit complexity.
AWS recommends key grants as the most efficient and secure way to provide temporary access to KMS keys for applications.

質問 # 121
A company has installed a third-party application that is distributed on several Amazon EC2 instances and on- premises servers. Occasionally, the company ' s IT team needs to use SSH to connect to each machine to perform software maintenance tasks. Outside these time slots, the machines must be completely isolated from the rest of the network. The company does not want to maintain any SSH keys. Additionally, the company wants to pay only for machine hours when there is an SSH connection.
Which solution will meet these requirements?

A. Create a bastion host with port forwarding to connect to the machines.
B. Use AWS CloudShell to create serverless connections.
C. Set up AWS Systems Manager Session Manager to allow temporary connections.
D. Set up an interface VPC endpoint for each machine for private connection.

正解：C

解説：
AWS Systems ManagerSession Managerprovides interactive shell access to managed instanceswithout inbound SSH,without bastion hosts, andwithout managing SSH keys. Access is controlled through IAM policies, and every session can be logged to CloudWatch Logs/S3 for auditability. This directly satisfies the
"no SSH keys" requirement and reduces the network exposure surface because you can keep port 22 closed and still obtain shell access when needed.
To meet the isolation requirement, the instances can be placed in private subnets with no inbound access, and you can use Systems Manager connectivity (via SSM endpoints/agents) for administrative sessions only when required. On-premises servers can also be managed by Systems Manager by registering them as managed instances (hybrid activations), allowing the same no-SSH-key operational model across EC2 and on-prem environments.
Options A and D still require network paths and do not eliminate key management; a bastion host is additional infrastructure that must be secured and maintained. CloudShell (Option C) is an AWS-managed shell environment but does not provide a direct, managed, keyless session channel into arbitrary EC2/on-prem hosts by itself. Therefore, Session Manager is the best solution.

質問 # 122
A security engineer needs to implement a logging solution that captures detailed information about objects in an Amazon S3 bucket. The solution must include details such as the IAM identity that makes the request and the time the object was accessed. The data must be structured and available in near real time.
Which solution meets these requirements?

A. Enable Amazon S3 server access logging on the S3 bucket. Create a new S3 bucket to store the logs. Analyze the logs from the logging S3 bucket.
B. Configure AWS Config rules to log access to the objects stored in the S3 bucket.
C. Enable AWS CloudTrail data event logging. Create a new S3 bucket to store the logs. Analyze the logs from the logging S3 bucket.
D. Enable Amazon Macie to log access to the objects stored in the S3 bucket.

正解：C

解説：
AWS CloudTrail data event logging is the correct solution because it is specifically designed to capture detailed, structured, and near-real-time API activity for Amazon S3 object-level operations. When S3 data events are enabled, CloudTrail records actions such as GetObject, PutObject, and DeleteObject, along with critical context including the IAM principal, source IP address, event time, request parameters, and response elements. These logs are delivered in JSON format, making them highly structured and suitable for security analysis, SIEM integration, and automated detection workflows.
