Amazon AWS Certified Security - Specialty 認定 SCS-C03 試験問題 (Q55-Q60):

質問 # 55
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 a new customer managed key in AWS Key Management Service (AWS KMS).
B. Create an AWS managed key for Amazon S3 in AWS KMS.
C. Change the SSE-S3 configuration on the S3 bucket to server-side encryption with AWS KMS managed keys (SSE-KMS).
D. Change the SSE-S3 configuration on the S3 bucket to server-side encryption with customer- provided keys (SSE-C).
E. Configure the PHP SDK to use the SSE-S3 key before upload.
F. Change all the S3 objects in the bucket to use the new encryption key.

正解：A、C、F

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 # 56
A company has two AWS accounts: Account A and Account B. Each account has a VPC. An application that runs in the VPC in Account A needs to write to an Amazon S3 bucket in Account B. The application in Account A already has permission to write to the S3 bucket in Account B. The application and the S3 bucket are in the same AWS Region. The company cannot send network traffic over the public internet.
Which solution will meet these requirements?

A. In Account A, create a gateway VPC endpoint for Amazon S3. Update the VPC route table in Account A.
B. In both accounts, create a transit gateway and VPC attachments in a subnet in each Availability Zone.Update the VPC route tables.
C. Deploy a software VPN appliance in Account A. Create a VPN connection between the software VPN appliance and a virtual private gateway in Account B.
D. Create a VPC peering connection between the VPC in Account A and the VPC in Account B. Update the VPC route tables, network ACLs, and security groups to allow network traffic between the peered IP ranges.

正解：A

解説：
To keep S3 accessoff the public internet, the standard AWS approach is to use anAmazon S3 gateway VPC endpoint(AWS PrivateLink for S3 is not used; S3 uses gateway endpoints). A gateway endpoint adds routes in the VPC route tables so traffic destined for S3 stays on the AWS backbone network rather than traversing an internet gateway, NAT gateway, or public IP paths. This satisfies the "cannot send traffic over the public internet" requirement while allowing the application in Account A to reach S3 in the same Region.
Cross-account bucket access is controlled byIAM and the S3 bucket policy, not by networking between the two accounts' VPCs. The bucket resides in S3 (a regional service), not inside Account B's VPC, so connecting VPC-to-VPC (peering, transit gateway, VPN) does not inherently provide private access to S3.
Those options would add complexity and still typically require internet/NAT unless S3 endpoints are used.
With the gateway endpoint in Account A, the application can privately reach S3, and because permissions are already granted to write to the bucket in Account B, the write operations will succeed without public internet routing.

質問 # 57
A company's security engineer is designing an isolation procedure for Amazon EC2 instances as part of an incident response plan. The security engineer needs to isolate a target instance to block any traffic to and from the target instance, except for traffic from the company's forensics team. Each of the company's EC2 instances has its own dedicated security group. The EC2 instances are deployed in subnets of a VPC. A subnet can contain multiple instances.
The security engineer is testing the procedure for EC2 isolation and opens an SSH session to the target instance. The procedure starts to simulate access to the target instance by an attacker. The security engineer removes the existing security group rules and adds security group rules to give the forensics team access to the target instance on port 22.
After these changes, the security engineer notices that the SSH connection is still active and usable. When the security engineer runs a ping command to the public IP address of the target instance, the ping command is blocked.
What should the security engineer do to isolate the target instance?

A. Add an inbound rule to the security group to allow traffic from 0.0.0.0/0 for all ports. Add an outbound rule to the security group to allow traffic to 0.0.0.0/0 for all ports. Then immediately delete these rules.
B. Create a network ACL that is associated with the target instance's subnet. Add a rule at the top of the inbound rule set to deny all traffic from 0.0.0.0/0. Add a rule at the top of the outbound rule set to deny all traffic to 0.0.0.0/0.
C. Create an AWS Systems Manager document that adds a host-level firewall rule to block all inbound traffic and outbound traffic. Run the document on the target instance.
D. Remove the port 22 security group rule. Attach an instance role policy that allows AWS Systems Manager Session Manager connections so that the forensics team can access the target instance.

正解：B

解説：
Amazon EC2 security groups arestateful, meaning that once a connection is established, return traffic is automatically allowed, even if the inbound rule that originally permitted the connection is later removed.
According to the AWS Certified Security - Specialty Official Study Guide and Amazon EC2 security documentation,existing connections are not terminated when security group rules change. This explains why the SSH session remains active even after the security group rules were modified, while new traffic such as ICMP ping is blocked.
To immediately and fully isolate an EC2 instance during an incident response scenario, AWS recommends usingstateless network controls. Amazon VPC network ACLs (NACLs) arestateless, which means that every packet is evaluated against the ACL rules regardless of whether the traffic is part of an existing connection. When a deny rule is added,all traffic is immediately blocked, including active sessions.
By creating a network ACL and associating it with the subnet that contains the target instance, and by adding explicit deny rules with the lowest rule numbers for both inbound and outbound traffic, the security engineer ensures thatall network communication to and from the instance is immediately interrupted. This approach satisfies the requirement to isolate the instance while preserving its runtime state and memory for forensic analysis.
Other options fail to meet the requirement because security group modifications do not terminate existing sessions, Systems Manager does not enforce network isolation, and host-level firewall changes require instance-level access and do not provide immediate, network-enforced isolation.

質問 # 58
A company's security policy requires all Amazon EC2 instances to use the Amazon Time Sync Service. AWS CloudTrail trails are enabled in all of the company's AWS accounts. VPC flow logs are enabled for all VPCs.
A security engineer must identify any EC2 instances that attempt to use Network Time Protocol (NTP) servers on the internet.
Which solution will meet these requirements?

A. Monitor VPC flow logs for traffic to the Amazon Time Sync Service.
B. Monitor CloudTrail logs for API calls to non-standard time servers.
C. Monitor CloudTrail logs for API calls to the Amazon Time Sync Service.
D. Monitor VPC flow logs for traffic to non-standard time servers.

正解：D

解説：
To identify EC2 instances attempting to use Network Time Protocol (NTP) servers on the internet instead of the Amazon Time Sync Service, monitoring VPC flow logs is appropriate. VPC flow logs capture details about traffic to and from EC2 instances, including any traffic directed to external NTP servers. By analyzing these logs for traffic to non-standard time servers (IP addresses other than the Amazon Time Sync Service endpoint ), the security engineer can identify instances that are not complying with the company's policy.

質問 # 59
A company runs an online game on AWS. When players sign up for the game, their username and password credentials are stored in an Amazon Aurora database.
The number of users has grown to hundreds of thousands of players. The number of requests for password resets and login assistance has become a burden for the company's customer service team.
The company needs to implement a solution to give players another way to log in to the game. The solution must remove the burden of password resets and login assistance while securely protecting each player's credentials.
Which solution will meet these requirements?

A. When a new player signs up, use an AWS Lambda function to automatically create an IAM access key and a secret access key.
B. Configure Amazon Cognito user pools to federate access to the game with third-party identity providers (IdPs), such as social IdPs. Migrate the game's authentication mechanism to Cognito.
C. Issue API keys to new and existing players and use Amazon API Gateway for authentication.
D. Migrate the player credentials from the Aurora database to AWS Secrets Manager.

正解：B

解説：
Amazon Cognito is a fully managed identity service that providesuser authentication, authorization, and user managementfor web and mobile applications. According to AWS Certified Security - Specialty documentation, Cognito user pools are specifically designed to offload authentication responsibilities from applications while maintaining strong security controls.
By federating authentication with third-party identity providers (such as social IdPs), Cognito eliminates the need for the company to manage user passwords directly. This dramatically reduces password reset requests and customer service overhead, while also improving security throughindustry-standard authentication mechanisms, including MFA and token-based access.
Option A is insecure and incorrect because IAM access keys are not intended for end users. Option B simply relocates password storage and does not reduce operational burden. Option D uses API keys, which are not designed for user authentication and provide no identity verification.
AWS guidance clearly states thatAmazon Cognito is the recommended service for scalable, secure user authentication, especially when reducing password management complexity is a requirement.
