質問 # 84
A security engineer received an Amazon GuardDuty alert indicating a finding involving the Amazon EC2 instance that hosts the company ' s primary website. The GuardDuty finding received read:
UnauthorizedAccess:IAMUser/InstanceCredentialExfiltration. The security engineer confirmed that a malicious actor used API access keys intended for the EC2 instance from a country where the company does not operate. The security engineer needs to deny access to the malicious actor.
What is the first step the security engineer should take?
正解：B
解説：
The findingInstanceCredentialExfiltrationindicates that credentials available to the EC2 instance (from the instance profile / IMDS) were likely stolen and then used from an unusual location. The fastest way todeny the malicious actor immediatelyis to invalidate the stolen, currently usable credentials. Because these aretemporary credentialsissued to the instance profile role, the correct first containment action is torevoke active sessionsfor that role so the stolen session credentials stop working. This directly blocks continued API use while you continue investigation and remediation.
Changing security groups (Option A) affects inbound network access to the website but does not stop an attacker from using stolen API credentials against AWS APIs. Installing agents and running assessments (Options B and C) are investigative steps that take time and do not immediately cut off the attacker's current access. After revoking sessions, best practice incident response typically continues with additional containment and eradication steps such as rotating credentials, reviewing CloudTrail for actions taken, checking for persistence (new IAM users/keys, modified policies), patching the instance, and restricting IMDS (for example, enforcing IMDSv2) to reduce risk of further credential theft.
質問 # 85
A company has enabled AWS Config for its organization in AWS Organizations. The company has deployed hundreds of Amazon S3 buckets across the organization. A security engineer needs to identify any S3 buckets that are not encrypted with AWS Key Management Service (AWS KMS). The security engineer also must prevent objects that are not encrypted with AWS KMS from being uploaded to the S3 buckets.
Which solution will meet these requirements?
正解：B
解説：
The correct Config rule for finding buckets that are not usingSSE-KMS by defaultiss3-default-encryption- kms. It evaluates the bucket's default encryption settings and flags buckets that do not have KMS default encryption enabled. The s3-bucket-ssl-requests-only rule focuses on enforcing HTTPS-only requests and does not validate encryption-at-rest settings, so it cannot satisfy the "identify not encrypted with KMS" requirement.
For preventing uploads of objects that are not encrypted with KMS, an organization-wide control is needed.
AnSCPcan restrict s3:PutObject so that uploads succeed only when the request specifiesSSE-KMS(and optionally a specific KMS key). This provides broad, low-touch enforcement across many accounts and buckets. While bucket policies can also enforce SSE-KMS, managing and verifying hundreds of bucket policies is more operationally heavy than a centrally managed SCP guardrail.
Option B enforcesSSE-S3, which does not meet the requirement forKMSencryption. Option D uses the wrong Config rule and relies on an "allow-only" pattern rather than explicit deny logic, making it an unreliable fit for the stated goal. Therefore, A is the best answer.
質問 # 86
A company is using Amazon Elastic Container Service (Amazon ECS) to deploy an application that deals with sensitive data. During a recent security audit, the company identified a security issue in which Amazon RDS credentials were stored with the application code in the company's source code repository. A security engineer needs to develop a solution to ensure that database credentials are stored securely and rotated periodically. The credentials should be accessible to the application only. The engineer also needs to prevent database administrators from sharing database credentials as plaintext with other teammates. The solution must also minimize administrative overhead.
Which solution meets these requirements?
正解：D
解説：
AWS Secrets Manageris the AWS service designed to store secrets securely and to supportautomatic rotationon a schedule--commonly used for Amazon RDS credentials. Storing credentials in Secrets Manager removes them from source code, enables fine-grained access control, and supports auditability of secret retrieval through CloudTrail. Rotation can be configured to periodically change the database password and update the stored secret automatically, minimizing operational overhead compared to manual rotation processes.
To ensure the credentials are accessibleonly to the application, the correct ECS pattern is to useIAM roles for tasks. A task role can be scoped to allow only secretsmanager:GetSecretValue (and related actions if needed) for the specific secret ARN. Only tasks running with that role can retrieve the secret at runtime, which prevents broad access. This also helps reduce the risk of database administrators sharing plaintext credentials, because the recommended operational model is that humans should not need direct access; the application retrieves the secret programmatically, and access can be limited to break-glass workflows if required.
質問 # 87
A company experienced a security incident caused by a vulnerable container image that was pushed from an external CI/CD pipeline into Amazon ECR. Which solution will prevent vulnerable images from being pushed?
正解：C
解説：
Amazon Inspector provides native CI/CD integration capabilities that allow security checks to occur before container images are pushed to Amazon ECR. According to AWS Certified Security
- Specialty documentation, Inspector does not block image pushes automatically. Instead, prevention must occur inside the CI/CD pipeline itself.
By generating a Software Bill of Materials (SBOM) using the Amazon Inspector SBOM generator and submitting it to Inspector for scanning, the pipeline can detect critical vulnerabilities before the image is uploaded. If vulnerabilities exceed policy thresholds, the pipeline fails, preventing deployment.
Post-push scanning solutions only detect vulnerabilities after exposure. Event-driven blocking does not prevent the initial risk.
AWS best practices require "shift-left" security controls to prevent vulnerable artifacts from entering production.
質問 # 88
A company needs to develop a code-signing application that will use a certificate authority (CA) to sign a code-signing certificate. The solution must use an AWS Key Management Service (AWS KMS) asymmetric key. The solution needs to collect and store immutable evidence about the creation, origin, and use of the KMS key for compliance purposes. This information must be made available to internal auditors.
Which solution meets these requirements?
正解：D
解説：
AWS CloudTrail records AWS KMS key management and usage events, including key creation and API calls that reference the KMS key. Storing the validated CloudTrail logs in an S3 bucket with Object Lock provides immutable evidence for compliance, and auditors can be granted read access to review the key's creation, origin-related events, and subsequent use.
