Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q78-Q83):

質問 # 78
A company hosts a web-based application that captures and stores sensitive data in an Amazon DynamoDB table. The company needs to implement a solution that provides end-to-end data protection and the ability to detect unauthorized data changes. Which solution will meet these requirements?

  • A. Use the AWS Encryption SDK. Use client-side encryption. Sign the table items.
  • B. Use an AWS Key Management Service (AWS KMS) customer managed key. Encrypt the data at rest.
  • C. Use the DynamoDB Encryption Client. Use client-side encryption. Sign the table items.
  • D. Use AWS Private Certificate Authority. Encrypt the data in transit.

正解：C

解説：
The DynamoDB Encryption Client provides end-to-end data protection by encrypting data on the client side before it is stored in DynamoDB and decrypting it when retrieved. This ensures that sensitive data remains protected both at rest and in transit. Additionally, the client allows you to digitally sign items, which provides integrity verification and enables detection of unauthorized changes to the data.


質問 # 79
A security engineer needs to protect a public web application that runs in a VPC. The VPC hosts the origin for an Amazon CloudFront distribution. The application has experienced multiple layer 7 DDoS attacks. An AWS WAF web ACL is associated with the CloudFront distribution. The web ACL contains one AWS managed rule to protect against known IP addresses that have bad reputations.
The security engineer must configure an automated solution that detects and mitigates layer 7 DDoS attacks in real time with no manual effort.
Which solution will meet these requirements?

  • A. Deploy AWS Network Firewall in the VPC. Create security policies that detect DDoS indicators.
    Create an AWS Lambda function to automatically update the web ACL rules during an attack.
  • B. Add a rate-based rule to the web ACL. Enable AWS Shield Advanced. Enable automatic application layer DDoS mitigation on the CloudFront distribution.
  • C. Enable AWS Shield Advanced on the CloudFront distribution. Configure alerts in Amazon CloudWatch for DDoS indicators.
  • D. Enable AWS Shield Advanced and configure proactive engagement with the AWS DDoS Response Team (DRT).

正解：B

解説：
Option D is the correct solution because it provides fully automated, real-time detection and mitigation of application-layer (Layer 7) DDoS attacks with no manual intervention. AWS Shield Advanced includes automatic application layer DDoS mitigation when it is enabled for supported resources such as Amazon CloudFront distributions. This feature continuously monitors traffic patterns and, when an attack is detected, automatically deploys AWS WAF rules to mitigate malicious requests.
Adding a rate-based rule to the AWS WAF web ACL further strengthens protection by automatically blocking IP addresses that exceed a defined request threshold, which is a common characteristic of Layer 7 DDoS attacks. This combination aligns directly with AWS best practices for protecting web applications against volumetric and application-layer threats.


質問 # 80
A company needs to implement data lifecycle management for Amazon RDS snapshots. The company will use AWS Backup to manage the snapshots.
The company must retain RDS automated snapshots for 5 years and will use Amazon S3 for long-term archival storage.
Which solution will meet these requirements?

  • A. Create an S3 Lifecycle policy. Include a 5-year retention period for the S3 bucket that AWS Backup uses for the RDS snapshots.
  • B. Create a backup plan in AWS Backup. Configure a 5-year retention period.
  • C. Use AWS Backup to apply a 5-year retention tag to the RDS snapshots.
  • D. Enable versioning on the S3 bucket that AWS Backup uses for the RDS snapshots. Configure a
    5-year retention period.

正解：B

解説：
AWS Backup allows you to create backup plans that include defined retention periods for managing the lifecycle of RDS snapshots. By configuring a 5- year retention period in the AWS Backup plan, the company can ensure that RDS snapshots are retained for the required duration.
AWS Backup can also handle moving backups to Amazon S3 for long-term archival storage as specified in the backup plan.


質問 # 81
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 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.
  • B. 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.
  • C. 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.
  • D. Export the KMS key material to an on-premises hardware security module (HSM). Give the application team access to the key material.

正解：C

解説：
KMS grantsare purpose-built for givingtemporary, scoped permissionsto use a customer managed key without continually editing key policies. A grant can allow only the specific cryptographic operations the application process needs (for example, Encrypt/Decrypt/GenerateDataKey) and can be constrained to a particular AWS principal and (optionally) conditions. When access is no longer required, the security team canrevokethe grant immediately, returning the key to its previous access posture. This meets the "temporary access occasionally" requirement with minimal operational work and lower risk than policy churn.
Option B requires repeated key policy edits and rollbacks, which is operationally noisy and increases the chance of misconfiguration or leaving access in place longer than intended. Option A is not supported in the way described-KMS key material for standard KMS customer managed keys is not something you "export" for sharing, and exposing key material breaks managed key controls. Option D introduces significant overhead and complexity by generating/importing key material repeatedly and is not the intended model for occasional access. Grants are the standard AWS pattern for delegating KMS key usage temporarily and safely.


質問 # 82
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?

  • A. 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.
  • B. Update the S3 bucket policy to ensure that clients that use pre-signed URLs have the S3:Get* permission and the S3:List* permission to access S3 objects in the bucket.
  • C. 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 pre-signed URLs.
  • D. 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 pre-signed URLs.

正解：A

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.
