Amazon AWS Certified Security – Specialty 認定 SCS-C03 試験問題 (Q50-Q55):質問 # 50
A company is operating an open-source software platform that is internet facing. The legacy software platform no longer receives security updates. The software platform operates using Amazon Route 53 weighted load balancing to send traffic to two Amazon EC2 instances that connect to an Amazon RDS cluster. A recent report suggests this software platform is vulnerable to SQL injection attacks, with samples of attacks provided. The company's security engineer must secure this system against SQL injection attacks within 24 hours. The solution must involve the least amount of effort and maintain normal operations during implementation.
What should the security engineer do to meet these requirements?
  • A. Create an Amazon CloudFront distribution specifying one EC2 instance as an origin. Create an AWS WAF web ACL containing rules that protect the application from this attack, then apply it to the distribution. Test to ensure the vulnerability has been mitigated, then redirect the Route 53 records to point to CloudFront.
  • B. Obtain the latest source code for the platform and make the necessary updates. Test the updated code to ensure that the vulnerability has been mitigated, then deploy the patched version of the platform to the EC2 instances.
  • C. Create an Application Load Balancer with the existing EC2 instances as a target group. Create an AWS WAF web ACL containing rules that protect the application from this attack, then apply it to the ALB.
    Test to ensure the vulnerability has been mitigated, then redirect the Route 53 records to point to the ALB. Update security groups on the EC2 instances to prevent direct access from the internet.
  • D. Update the security group that is attached to the EC2 instances, removing access from the internet to the TCP port used by the SQL database. Create an AWS WAF web ACL containing rules that protect the application from this attack, then apply it to the EC2 instances.
正解：C
解説：
AWS WAF provides managed and custom rules that can immediately mitigate common web exploits such as SQL injection without modifying application code. According to AWS Certified Security - Specialty documentation, placing AWS WAF in front of an Application Load Balancer is a recommended rapid- response control for legacy applications with known vulnerabilities.
Creating an ALB in front of the existing EC2 instances allows seamless traffic migration. AWS WAF SQL injection rules can be deployed and tested without downtime. Updating Route 53 to point to the ALB preserves normal operations. Restricting EC2 security groups afterward prevents bypassing the WAF.
Option B introduces CloudFront changes and single-origin testing, increasing complexity. Option C cannot be completed within 24 hours and risks downtime. Option D is invalid because AWS WAF cannot be attached directly to EC2 instances.

質問 # 51
A company hosts its public website on Amazon EC2 instances behind an Application Load Balancer (ALB).
The website is experiencing a global DDoS attack from a specific IoT device brand that uses a unique user agent. A security engineer is creating an AWS WAF web ACL and will associate it with the ALB.
Which rule statement will mitigate the current attack and future attacks from these IoT devices without blocking legitimate customers?
  • A. Use a rate-based rule statement.
  • B. Use a geographic match rule statement.
  • C. Use a string match rule statement on the user agent.
  • D. Use an IP set match rule statement.
正解：C
解説：
AWS WAF string match rule statements allow inspection of HTTP headers, including the User-Agent header.
According to AWS Certified Security - Specialty guidance, when malicious traffic can be uniquely identified by a consistent request attribute, such as a device-specific user agent, a string match rule provides precise mitigation with minimal false positives.
IP-based blocking is ineffective for globally distributed botnets. Geographic blocking risks denying access to legitimate users. Rate-based rules limit request volume but do not prevent low-and-slow attacks.
By matching the unique IoT device brand in the User-Agent header, the security engineer can block only malicious requests while preserving customer access.

質問 # 52
A company has a PHP-based web application that uses Amazon S3 as an object store for user files. The S3 bucket is configured for server-side encryption with Amazon S3 managed keys (SSE-S3). New requirements mandate full control of encryption keys.
Which combination of steps must a security engineer take to meet these requirements? (Select THREE.)
  • A. Create an AWS managed key for Amazon S3 in AWS KMS.
  • B. Create a new customer managed key in AWS Key Management Service (AWS KMS).
  • C. Change the SSE-S3 configuration on the S3 bucket to server-side encryption with customer-provided keys (SSE-C).
  • D. Change all the S3 objects in the bucket to use the new encryption key.
  • E. Change the SSE-S3 configuration on the S3 bucket to server-side encryption with AWS KMS managed keys (SSE-KMS).
  • F. Configure the PHP SDK to use the SSE-S3 key before upload.
正解：B、D、E
解説：
SSE-S3 uses AWS-managed keys and does not provide customer control. AWS Certified Security - Specialty documentation states that SSE-KMS with customer managed keys allows full control, auditing, and key rotation. The security engineer must first create a customer managed KMS key, then update the bucket to use SSE-KMS. Existing objects must be re-encrypted to ensure compliance.
SSE-C requires the application to manage keys, increasing complexity and risk. AWS managed keys do not meet the requirement for customer-controlled encryption.

質問 # 53
A company runs an internet-accessible application on several Amazon EC2 instances that run Windows Server. The company used an instance profile to configure the EC2 instances. A security team currently accesses the VPC that hosts the EC2 instances by using an AWS Site-to-Site VPN tunnel from an on-premises office.
The security team issues a policy that requires all external access to the VPC to be blocked in the event of a security incident. However, during an incident, the security team must be able to access the EC2 instances to obtain forensic information on the instances.
Which solution will meet these requirements?
  • A. Install EC2 Instance Connect on the EC2 instances. Configure the instances to permit access to the ec2- instance-connect command user. Use the AWS Management Console to connect to the EC2 instances.
  • B. Create an EC2 Instance Connect endpoint in the VPC. Configure an appropriate security group to allow access between the EC2 instances and the endpoint. Use the AWS CLI to open a tunnel to connect to the instances.
  • C. Install EC2 Instance Connect on the EC2 instances. Update the IAM policy for the IAM role to grant the required permissions. Use the AWS CLI to open a tunnel to connect to the instances.
  • D. Create an EC2 Instance Connect endpoint in the VPC. Configure an appropriate security group to allow access between the EC2 instances and the endpoint. Use the AWS Management Console to connect to the EC2 instances.
正解：D
解説：
EC2 Instance Connect endpoints provide secure, private connectivity to EC2 instances without requiring public IP addresses, inbound internet access, or VPN connectivity. According to AWS Certified Security - Specialty documentation, Instance Connect endpoints are designed specifically for incident response and secure administrative access scenarios.
By deploying an EC2 Instance Connect endpoint in the VPC, the security team can block all external network access while still maintaining controlled access to EC2 instances through the AWS Management Console.
The endpoint uses AWS-managed infrastructure and private connectivity, and access is authorized using IAM policies and instance profiles.
Options A and B rely on direct EC2 Instance Connect installation and network paths that may still depend on external access. Option C is incorrect because tunneling is not required when using the console-based Instance Connect endpoint.
This solution enables forensic access during incidents without reopening external network paths, aligning with AWS incident response best practices.

質問 # 54
A security administrator is setting up a new AWS account. The security administrator wants to secure the data that a company stores in an Amazon S3 bucket. The security administrator also wants to reduce the chance of unintended data exposure and the potential for misconfiguration of objects that are in the S3 bucket.
Which solution will meet these requirements with the LEAST operational overhead?
  • A. Deactivate ACLs for objects that are in the bucket.
  • B. Use AWS PrivateLink for Amazon S3 to access the bucket.
  • C. Configure the S3 Block Public Access feature for all objects that are in the bucket.
  • D. Configure the S3 Block Public Access feature for the AWS account.
正解：D
解説：
Amazon S3 Block Public Access configured at the AWS account level is the recommended and most effective approach to protect data stored in Amazon S3 while minimizing operational overhead. AWS Security Specialty documentation explains that S3 Block Public Access provides centralized, preventative controls designed to block public access to S3 buckets and objects regardless of individual bucket policies or object- level ACL configurations. When enabled at the account level, these controls automatically apply to all existing and newly created buckets, significantly reducing the risk of accidental exposure caused by misconfigured permissions.
The AWS Certified Security - Specialty Study Guide emphasizes that public access misconfiguration is a leading cause of data leaks in cloud environments. Account-level S3 Block Public Access acts as a guardrail by overriding any attempt to grant public permissions through bucket policies or ACLs. This eliminates the need to manage security settings on a per-bucket or per-object basis, thereby reducing administrative complexity and human error.
Configuring Block Public Access at the object level, as in option B, requires continuous monitoring and manual configuration, which increases operational overhead. Disabling ACLs alone, as described in option C, does not fully prevent public access because bucket policies can still allow public permissions. Using AWS PrivateLink, as in option D, controls network access but does not protect against public exposure through misconfigured S3 policies.
AWS security best practices explicitly recommend enabling S3 Block Public Access at the account level as the primary mechanism for preventing unintended public data exposure with minimal management effort.
