Amazon AWS Certified Security - Specialty SCS-C02 Prüfungsfragen mit Lösungen (Q155-Q160):

155. Frage
A company's data scientists want to create AI/ML training models using Amazon SageMaker. The training models will use large datasets in an Amazon S3 bucket. The datasets contain sensitive information. On average, the data scientists need 30 days to train models. The S3 bucket has been secured appropriately. The company's data retention policy states that all data older than 45 days must be removed from the S3 bucket.

A. Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an Amazon EventBridge rule to invoke the Lambda function each month.
B. Create an AWS Lambda function to check the last-modified date of the S3 objects and delete objects that are older than 45 days. Create an S3 event notification to invoke the Lambda function for each PutObject operation.
C. Configure an S3 Lifecycle rule on the S3 bucket to delete objects after 45 days.
D. Configure S3 Intelligent-Tiering on the S3 bucket to automatically transition objects to another storage class.

Antwort: C

Begründung:
Comprehensive Detailed Explanation with all AWS References
The simplest and most efficient way to enforce a data retention policy in Amazon S3 is by using S3 Lifecycle rules:
* S3 Lifecycle Rule:
* Lifecycle rules allow you to automatically delete objects based on their age or last-modified date.
* Specify a rule to delete objects after 45 days to meet the retention policy.

156. Frage
A security engineer must use AWS Key Management Service (AWS KMS) to design a key management solution for a set of Amazon Elastic Block Store (Amazon EBS) volumes that contain sensitive data. The solution needs to ensure that the key material automatically expires in 90 days.
Which solution meets these criteria?

A. An AWS managed CMK
B. A customer managed CMK that uses AWS provided key material
C. Operation system-native encryption that uses GnuPG
D. A customer managed CMK that uses customer provided key material

Antwort: D

Begründung:
Explanation
https://awscli.amazonaws.com/v2/documentation/api/latest/reference/kms/import-key-material.html aws kms import-key-material
--key-id 1234abcd-12ab-34cd-56ef-1234567890ab
--encrypted-key-material fileb://EncryptedKeyMaterial.bin
--import-token fileb://ImportToken.bin
--expiration-model KEY_MATERIAL_EXPIRES
--valid-to 2021-09-21T19:00:00Z
The correct answer is A. A customer managed CMK that uses customer provided key material.
A customer managed CMK is a KMS key that you create, own, and manage in your AWS account. You have full control over the key configuration, permissions, rotation, and deletion. You can use a customer managed CMK to encrypt and decrypt data in AWS services that are integrated with AWS KMS, such as Amazon EBS1.
A customer managed CMK can use either AWS provided key material or customer provided key material.
AWS provided key material is generated by AWS KMS and never leaves the service unencrypted. Customer provided key material is generated outside of AWS KMS and imported into a customer managed CMK. You can specify an expiration date for the imported key material, after which the CMK becomes unusable until you reimport new key material2.
To meet the criteria of automatically expiring the key material in 90 days, you need to use customer provided key material and set the expiration date accordingly. This way, you can ensure that the data encrypted with the CMK will not be accessible after 90 days unless you reimport new key material and re-encrypt the data.
The other options are incorrect for the following reasons:
B: A customer managed CMK that uses AWS provided key material does not expire automatically. You can enable automatic rotation of the key material every year, but this does not prevent access to the data encrypted with the previous key material. You would need to manually delete the CMK and its backing key material to make the data inaccessible3.
C: An AWS managed CMK is a KMS key that is created, owned, and managed by an AWS service on your behalf. You have limited control over the key configuration, permissions, rotation, and deletion. You cannot use an AWS managed CMK to encrypt data in other AWS services or applications. You also cannot set an expiration date for the key material of an AWS managed CMK4.
D: Operation system-native encryption that uses GnuPG is not a solution that uses AWS KMS. GnuPG is a command line tool that implements the OpenPGP standard for encrypting and signing data. It does not integrate with Amazon EBS or other AWS services. It also does not provide a way to automatically expire the key material used for encryption5.

157. Frage
A company has an AWS Lambda function that creates image thumbnails from larger images. The Lambda function needs read and write access to an Amazon S3 bucket in the same AWS account.
Which solutions will provide the Lambda function this access? (Select TWO.)

A. Create an IAM role for the Lambda function. Attach a bucket policy to the S3 bucket to allow access. Specify the function's IAM role as the princi-pal.
B. Create an IAM user that has only programmatic access. Create a new access key pair. Add environmental variables to the Lambda function with the ac-cess key ID and secret access key. Modify the Lambda function to use the environmental variables at run time during communication with Amazon S3.
C. Generate an Amazon EC2 key pair. Store the private key in AWS Secrets Man-ager. Modify the Lambda function to retrieve the private key from Secrets Manager and to use the private key during communication with Amazon S3.
D. Create a security group. Attach the security group to the Lambda function. Attach a bucket policy that allows access to the S3 bucket through the se-curity group ID.
E. Create an IAM role for the Lambda function. Attach an IAM policy that al-lows access to the S3 bucket.

Antwort: A,E

158. Frage
A company stores images for a website in an Amazon S3 bucket. The company is using Amazon CloudFront to serve the images to end users. The company recently discovered that the images are being accessed from countries where the company does not have a distribution license.
Which actions should the company take to secure the images to limit their distribution? (Select TWO.)

A. Enable the Restrict Viewer Access option in CloudFront to create a deny list of countries where the company lacks a license.
B. Update the website DNS record to use an Amazon Route 53 geolocation record deny list of countries where the company lacks a license.
C. Update the S3 bucket policy with a deny list of countries where the company lacks a license.
D. Add a CloudFront geo restriction deny list of countries where the company lacks a license.
E. Update the S3 bucket policy to restrict access to a CloudFront origin access identity (OAI).

Antwort: D,E

159. Frage
A company has an application that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Amazon EC2 Auto Scaling group and are attached to Amazon Elastic Blodfc Store (Amazon EBS) volumes.
A security engineer needs to preserve all forensic evidence from one of the instances.
Which order of steps should the security engineer use to meet this requirement?

A. Take an EBS volume snapshot of the instance and store the snapshot in an Amazon S3 bucket. Take a memory snapshot of the instance and store the snapshot in an S3 bucket. Detach the instance from the Auto Scaling group. Deregister the instance from the ALB. Stop the instance.
B. Detach the instance from the Auto Scaling group. Deregister the instance from the ALB. Take an EBS volume snapshot of the instance and store the snapshot in an Amazon S3 bucket. Take a memory snapshot of the instance and store the snapshot in an S3 bucket. Stop the instance
C. Detach the instance from the Auto Scaling group Deregister the instance from the ALB. Stop the instance. Take a memory snapshot of the instance and store the snapshot in an Amazon S3 bucket. Take an EBS volume snapshot of the instance and store the snapshot in an S3 bucket.
D. Take a memory snapshot of the instance and store the snapshot in an Amazon S3 bucket. Stop the instance. Take an EBS volume snapshot of the instance and store the snapshot in an S3 bucket. Detach the instance from the Auto Scaling group. Deregister the instance from the ALB.

Antwort: D

Begründung:
The correct answer is B because it preserves the forensic evidence from the instance in the correct order. The first step is to take a memory snapshot of the instance and store it in an S3 bucket, as memory data is volatile and can be lost when the instance is stopped. The second step is to stop the instance, which will prevent any further changes to the EBS volume. The third step is to take an EBS volume snapshot of the instance and store it in an S3 bucket, which will capture the disk state of the instance. The last two steps are to detach the instance from the Auto Scaling group and deregister it from the ALB, which will isolate the instance from the rest of the application.
The other options are incorrect because they do not preserve the forensic evidence in the correct order. Option A takes the EBS volume snapshot before the memory snapshot, which can result in inconsistent data. Option C detaches and deregisters the instance before taking any snapshots, which can affect the availability of the application. Option D stops the instance before taking the memory snapshot, which can cause the loss of memory data.
