AWS Certified Security - Specialty Questions and Answers

Question 5

A company manages multiple AWS accounts using AWS Organizations. The company's security team notices that some member accounts are not sending AWS CloudTrail logs to a centralized Amazon S3 logging bucket. The security team wants to ensure there is at least one trail configured for all existing accounts and for any account that is created in the future.

Which set of actions should the security team implement to accomplish this?

Options:

Create a new trail and configure it to send CloudTraiI logs to Amazon S3. Use Amazon EventBridge to send notification if a trail is deleted or stopped.

Deploy an AWS Lambda function in every account to check if there is an existing trail and create a new trail, if needed.

Edit the existing trail in the Organizations management account and apply it to the organization.

Create an SCP to deny the cloudtraiI:DeIete• and cloudtraiI:Stop• actbns. Apply the SCP to all accounts.

Answer:

Explanation:

The correct answer is C. Edit the existing trail in the Organizations management account and apply it to the organization.

The reason is that this is the simplest and most effective way to ensure that there is at least one trail configured for all existing accounts and for any account that is created in the future. According to the AWS documentation1, “If you have created an organization in AWS Organizations, you can create a trail that logs all events for all AWS accounts in that organization. This is sometimes called an organization trail.” The documentation1 also states that “The management account for the organization can edit an existing trail in their account, and apply it to an organization, making it an organization trail. Organization trails log events for the management account and all member accounts in the organization.” Therefore, by editing the existing trail in the management account and applying it to the organization, the security team can ensure that all accounts are sending CloudTrail logs to a centralized S3 logging bucket.

The other options are incorrect because:

A. Create a new trail and configure it to send CloudTrail logs to Amazon S3. Use Amazon EventBridge to send notification if a trail is deleted or stopped. This option is not sufficient to ensure that there is at least one trail configured for all accounts, because it does not prevent users from deleting or stopping the trail in their accounts. Even if EventBridge sends a notification, the security team would have to manually restore or restart the trail, which is not efficient or scalable.
B. Deploy an AWS Lambda function in every account to check if there is an existing trail and create a new trail, if needed. This option is not optimal because it requires deploying and maintaining a Lambda function in every account, which adds complexity and cost. Moreover, it does not prevent users from deleting or stopping the trail after it is created by the Lambda function.
D. Create an SCP to deny the cloudtrail:Delete and cloudtrail:Stop actions. Apply the SCP to all accounts. This option is not sufficient to ensure that there is at least one trail configured for all accounts, because it does not create or apply a trail in the first place. It only prevents users from deleting or stopping an existing trail, but it does not guarantee that a trail exists in every account.

Question 6

An Incident Response team is investigating an IAM access key leak that resulted in Amazon EC2 instances being launched. The company did not discover the incident until many months later The Director of Information Security wants to implement new controls that will alert when similar incidents happen in the future

Which controls should the company implement to achieve this? {Select TWO.)

Options:

Enable VPC Flow Logs in all VPCs Create a scheduled IAM Lambda function that downloads and parses the logs, and sends an Amazon SNS notification for violations.

Use IAM CloudTrail to make a trail, and apply it to all Regions Specify an Amazon S3 bucket to receive all the CloudTrail log files

Add the following bucket policy to the company's IAM CloudTrail bucket to prevent log tampering

{

"Version": "2012-10-17-,

"Statement": {

"Effect": "Deny",

"Action": "s3:PutObject",

"Principal": "-",

"Resource": "arn:IAM:s3:::cloudtrail/IAMLogs/111122223333/*"

}

Create an Amazon S3 data event for an PutObject attempts, which sends notifications to an Amazon SNS topic.

Create a Security Auditor role with permissions to access Amazon CloudWatch Logs m all Regions Ship the logs to an Amazon S3 bucket and make a lifecycle policy to ship the logs to Amazon S3 Glacier.

Verify that Amazon GuardDuty is enabled in all Regions, and create an Amazon CloudWatch Events rule for Amazon GuardDuty findings Add an Amazon SNS topic as the rule's target

Question 7

A company hosts a web application on an Apache web server. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The company configured the EC2 instances to send the Apache web server logs to an Amazon CloudWatch Logs group that the company has configured to expire after 1 year.

Recently, the company discovered in the Apache web server logs that a specific IP address is sending suspicious requests to the web application. A security engineer wants to analyze the past week of Apache web server logs to determine how many requests that the IP address sent and the corresponding URLs that the IP address requested.

What should the security engineer do to meet these requirements with the LEAST effort?

Options:

Export the CloudWatch Logs group data to Amazon S3. Use Amazon Macie to query the logs for the specific IP address and the requested URLs.

Configure a CloudWatch Logs subscription to stream the log group to an Am-azon OpenSearch Service cluster. Use OpenSearch Service to analyze the logs for the specific IP address and the requested URLs.

Use CloudWatch Logs Insights and a custom query syntax to analyze the CloudWatch logs for the specific IP address and the requested URLs.

Export the CloudWatch Logs group data to Amazon S3. Use AWS Glue to crawl the S3 bucket for only the log entries that contain the specific IP ad-dress. Use AWS Glue to view the results.

Question 8

A company is using IAM Organizations. The company wants to restrict IAM usage to the eu-west-1 Region for all accounts under an OU that is named "development." The solution must persist restrictions to existing and new IAM accounts under the development OU.
