AWS Certified Security - Specialty Questions and Answers

Question 105

A company hosts multiple externally facing applications, each isolated in its own IAM account The company'B Security team has enabled IAM WAF. IAM Config. and Amazon GuardDuty on all accounts. The company's Operations team has also joined all of the accounts to IAM Organizations and established centralized logging for CloudTrail. IAM Config, and GuardDuty. The company wants the Security team to take a reactive remediation in one account, and automate implementing this remediation as proactive prevention in all the other accounts.

How should the Security team accomplish this?

Options:

A.

Update the IAM WAF rules in the affected account and use IAM Firewall Manager to push updated IAM WAF rules across all other accounts.

B.

Use GuardDuty centralized logging and Amazon SNS to set up alerts to notify all application teams of security incidents.

C.

Use GuardDuty alerts to write an IAM Lambda function that updates all accounts by adding additional NACLs on the Amazon EC2 instances to block known malicious IP addresses.

D.

Use IAM Shield Advanced to identify threats in each individual account and then apply the account-based protections to all other accounts through Organizations.

Question 106

A company is planning to deploy a new log analysis environment. The company needs to implement a solution to analyze logs from multiple AWS services in near real time. The solution must provide the ability to search the logs. The solution also must send alerts to an existing Amazon Simple Notification Service (Amazon SNS) topic when specific logs match detection rules.

Which solution will meet these requirements?

Options:

A.

Analyze the logs by using Amazon OpenSearch Service. Search the logs from the OpenSearch API. Use OpenSearch Service Security Analytics to match logs with detection rules and to send alerts to the SNS topic.

B.

Analyze the logs by using AWS Security Hub. Search the logs from the Findings page in Security Hub. Create custom actions to match logs with detection rules and to send alerts to the SNS topic.

C.

Analyze the logs by using Amazon CloudWatch Logs. Use a subscription filter to match logs with detection rules and to send alerts to the SNS topic. Search the logs manually by using CloudWatch Logs Insights.

D.

Analyze the logs by using Amazon QuickSight. Search the logs by listing the query results in a dashboard. Run queries to match logs with detection rules and to send alerts to the SNS topic.

Question 107

A company has implemented IAM WAF and Amazon CloudFront for an application. The application runs on Amazon EC2 instances that are part of an Auto Scaling group. The Auto Scaling group is behind an Application Load Balancer (ALB).

The IAM WAF web ACL uses an IAM Managed Rules rule group and is associated with the CloudFront distribution. CloudFront receives the request from IAM WAF and then uses the ALB as the distribution's origin.

During a security review, a security engineer discovers that the infrastructure is susceptible to a large, layer 7 DDoS attack.

How can the security engineer improve the security at the edge of the solution to defend against this type of attack?

Options:

A.

Configure the CloudFront distribution to use the Lambda@Edge feature. Create an IAM Lambda function that imposes a rate limit on CloudFront viewer requests. Block the request if the rate limit is exceeded.

B.

Configure the IAM WAF web ACL so that the web ACL has more capacity units to process all IAM WAF rules faster.

C.

Configure IAM WAF with a rate-based rule that imposes a rate limit that automatically blocks requests when the rate limit is exceeded.

D.

Configure the CloudFront distribution to use IAM WAF as its origin instead of the ALB.

Question 108

A company is developing an ecommerce application. The application uses Amazon EC2 instances and an Amazon RDS MySQL database. For compliance reasons, data must be secured in transit and at rest. The company needs a solution that minimizes operational overhead and minimizes cost.

Which solution meets these requirements?

Options:

A.

Use TLS certificates from AWS Certificate Manager (ACM) with an Application Load Balancer. Deploy self-signed certificates on the EC2 instances. Ensure that the database client software uses a TLS connection to Amazon RDS. Enable encryption of the RDS DB instance. Enable encryption on the Amazon Elastic Block Store (Amazon EBS) volumes that support the EC2 instances.

B.

Use TLS certificates from a third-party vendor with an Application Load Balancer. Install the same certificates on the EC2 instances. Ensure that the database client software uses a TLS connection to Amazon RDS. Use AWS Secrets Manager for client-side encryption of application data.

C.

Use AWS CloudHSM to generate TLS certificates for the EC2 instances. Install the TLS certificates on the EC2 instances. Ensure that the database client software uses a TLS connection to Amazon RDS. Use the encryption keys form CloudHSM for client-side encryption of application data.

D.

Use Amazon CloudFront with AWS WAF. Send HTTP connections to the origin EC2 instances. Ensure that the database client software uses a TLS connection to Amazon RDS. Use AWS Key Management Service (AWS KMS) for client-side encryption of application data before the data is stored in the RDS database.
