A distributed web application is installed across several EC2 instances in public subnets residing in two Availability Zones. Apache logs show several intermittent brute-force attacks from hundreds of IP addresses at the layer 7 level over the past six months.
What would be the BEST way to reduce the potential impact of these attacks in the future?

A. Use custom route tables to prevent malicious traffic from routing to the instances. B. Update security groups to deny traffic from the originating source IP addresses. C. Use network ACLs. D. Install intrusion prevention software (IPS) on each instance.

A company plans to move most of its IT infrastructure to AWS. They want to leverage their existing on-premises Active Directory as an identity provider for AWS.
Which combination of steps should a Security Engineer take to federate the company's on-premises Active Directory with AWS? (Choose two.)

A. Create IAM roles with permissions corresponding to each Active Directory group. B. Create IAM groups with permissions corresponding to each Active Directory group. C. Configure Amazon Cloud Directory to support a SAML provider. D. Configure Active Directory to add relying party trust between Active Directory and AWS. E. Configure Amazon Cognito to add relying party trust between Active Directory and AWS.

A security alert has been raised for an Amazon EC2 instance in a customer account that is exhibiting strange behavior. The Security Engineer must first isolate theEC2 instance and then use tools for further investigation.
What should the Security Engineer use to isolate and research this event? (Choose three.)

A. AWS CloudTrail B. Amazon Athena C. AWS Key Management Service (AWS KMS) D. VPC Flow Logs E. AWS Firewall Manager F. Security groups

A financial institution has the following security requirements:
- Cloud-based users must be contained in a separate authentication domain.
- Cloud-based users cannot access on-premises systems.
As part of standing up a cloud environment, the financial institution is creating a number of Amazon managed databases and Amazon EC2 instances. An ActiveDirectory service exists on-premises that has all the administrator accounts, and these must be able to access the databases and instances.
How would the organization manage its resources in the MOST secure manner? (Choose two.)

A. Configure an AWS Managed Microsoft AD to manage the cloud resources. B. Configure an additional on-premises Active Directory service to manage the cloud resources. C. Establish a one-way trust relationship from the existing Active Directory to the new Active Directory service. D. Establish a one-way trust relationship from the new Active Directory to the existing Active Directory service. E. Establish a two-way trust between the new and existing Active Directory services.

An organization wants to be alerted when an unauthorized Amazon EC2 instance in its VPC performs a network port scan against other instances in the VPC.
When the Security team performs its own internal tests in a separate account by using pre-approved third-party scanners from the AWS Marketplace, the Security team also then receives multiple Amazon GuardDuty events from Amazon CloudWatch alerting on its test activities.
How can the Security team suppress alerts about authorized security tests while still receiving alerts about the unauthorized activity?

A. Use a filter in AWS CloudTrail to exclude the IP addresses of the Security team's EC2 instances. B. Add the Elastic IP addresses of the Security team's EC2 instances to a trusted IP list in Amazon GuardDuty. C. Install the Amazon Inspector agent on the EC2 instances that the Security team uses. D. Grant the Security team's EC2 instances a role with permissions to call Amazon GuardDuty API operations.

An organization is moving non-business-critical applications to AWS while maintaining a mission-critical application in an on-premises data center. An on-premises application must share limited confidential information with the applications in AWS. The internet performance is unpredictable.
Which configuration will ensure continued connectivity between sites MOST securely?

A. VPN and a cached storage gateway B. AWS Snowball Edge C. VPN Gateway over AWS Direct Connect D. AWS Direct Connect

An application has been built with Amazon EC2 instances that retrieve messages from Amazon SQS. Recently, IAM changes were made and the instances can no longer retrieve messages.
What actions should be taken to troubleshoot the issue while maintaining least privilege? (Choose two.)

A. Configure and assign an MFA device to the role used by the instances. B. Verify that the SQS resource policy does not explicitly deny access to the role used by the instances. C. Verify that the access key attached to the role used by the instances is active. D. Attach the AmazonSQSFullAccess managed policy to the role used by the instances. E. Verify that the role attached to the instances contains policies that allow access to the queue.

A company has a forensic logging use case whereby several hundred applications running on Docker on EC2 need to send logs to a central __cpLocation. The SecurityEngineer must create a logging solution that is able to perform real-time analytics on the log files, grants the ability to replay events, and persists data.
Which AWS Services, together, can satisfy this use case? (Choose two.)

A. Amazon Elasticsearch B. Amazon Kinesis C. Amazon SQS D. Amazon CloudWatch E. Amazon Athena

Which of the following is the most efficient way to automate the encryption of AWS CloudTrail logs using a Customer Master Key (CMK) in AWS KMS?

A. Use the KMS direct encrypt function on the log data every time a CloudTrail log is generated. B. Use the default Amazon S3 server-side encryption with S3-managed keys to encrypt and decrypt the CloudTrail logs. C. Configure CloudTrail to use server-side encryption using KMS-managed keys to encrypt and decrypt CloudTrail logs. D. Use encrypted API endpoints so that all AWS API calls generate encrypted CloudTrail log entries using the TLS certificate from the encrypted API call.

An organization is using AWS CloudTrail, Amazon CloudWatch Logs, and Amazon CloudWatch to send alerts when new access keys are created. However, the alerts are no longer appearing in the Security Operations mail box.
Which of the following actions would resolve this issue?

A. In CloudTrail, verify that the trail logging bucket has a log prefix configured. B. In Amazon SNS, determine whether the "Account spend limit" has been reached for this alert. C. In SNS, ensure that the subscription used by these alerts has not been deleted. D. In CloudWatch, verify that the alarm threshold "consecutive periods" value is equal to, or greater than 1.
