This educational approach ensures a complete understanding of key concepts and response strategies.- Alignment with Actual Exam Questions: According to feedback from consultants who prepared with our exams, many of the questions in our tests were actually encountered in their real exams. Our tests reflect the trends and topics addressed in the actual AWS exams, specifically for the months of November and December 2023.- Optimal Preparation: By practicing with our exams, you will familiarize yourself not only with the style and format of AWS questions but also develop a deep understanding of essential topics, preparing you to effectively answer a variety of questions in the real exam.This course is an invaluable opportunity for those looking to deepen their AWS security knowledge and feel fully prepared for the AWS Certified Security Specialty exam. Our commitment is to provide you with all the resources necessary to not only pass your exam but also to excel in your career as an AWS security professional.Here's a sample question and answerA security engineer needs to develop a process to investigate and respond to potential security events on a company's Amazon EC2 instances. All the EC2 instances are backed by Amazon Elastic Block Store (Amazon EBS). The company uses AWS Systems Manager to manage all the EC2 instances and has installed Systems Manager Agent (SSM Agent) on all the EC2 instances.The process that the security engineer is developing must comply with AWS security best practices and must meet the following requirements:A compromised EC2 instance's volatile memory and non-volatile memory must be preserved for forensic purposes.A compromised EC2 instance's metadata must be updated with corresponding incident ticket information.A compromised EC2 instance must remain online during the investigation but must be isolated to prevent the spread of malware.Any investigative activity during the collection of volatile data must be captured as part of the process.Which combination of steps should the security engineer take to meet these requirements with the LEAST operational overhead? (Choose three.)A. Gather any relevant metadata for the compromised EC2 instance. Enable termination protection. Isolate the instance by updating the instance's security groups to restrict access. Detach the instance from any Auto Scaling groups that the instance is a member of. Deregister the instance from any Elastic Load Balancing (ELB) resources.B. Gather any relevant metadata for the compromised EC2 instance. Enable termination protection. Move the instance to an isolation subnet that denies all source and destination traffic. Associate the instance with the subnet to restrict access. Detach the instance from any Auto Scaling groups that the instance is a member of. Deregister the instance from any Elastic Load Balancing (ELB) resources.C. Use Systems Manager Run Command to invoke scripts that collect volatile data.D. Establish a Linux SSH or Windows Remote Desktop Protocol (RDP) session to the compromised EC2 instance to invoke scripts that collect volatile data.E. Create a snapshot of the compromised EC2 instance's EBS volume for follow-up investigations. Tag the instance with any relevant metadata and incident ticket information.F. Create a Systems Manager State Manager association to generate an EBS volume snapshot of the compromised EC2 instance. Tag the instance with any relevant metadata and incident ticket information.Correct Options:Correct options:A. Gather any relevant metadata for the compromised EC2 instance. Enable termination protection. Isolate the instance by updating the instance's security groups to restrict access. Detach the instance from any Auto Scaling groups that the instance is a member of. Deregister the instance from any Elastic Load Balancing (ELB) resources.Option A outlines a set of steps to gather relevant information, protect the instance from accidental termination, isolate it from the network, and disassociate it from Auto Scaling groups and Elastic Load Balancing resources. These measures aim to preserve the compromised instance for forensic analysis while preventing further impact on the environment:Gather any relevant metadata for the compromised EC2 instance:This step involves collecting important information about the compromised EC2 instance, which could include instance ID, IP address, instance type, and any other relevant details. Gathering metadata is crucial for tracking and documenting the incident.Enable termination protection:Enabling termination protection helps prevent accidental termination of the EC2 instance. This is beneficial during an investigation to ensure that the compromised instance is not inadvertently terminated, preserving it for forensic analysis.Isolate the instance by updating the instance's security groups to restrict access:Updating the instance's security groups allows you to modify its network access controls. By restricting access, you isolate the compromised instance from the rest of the network, preventing potential lateral movement of an attacker within the environment.Detach the instance from any Auto Scaling groups that the instance is a member of:If the EC2 instance is part of an Auto Scaling group, detaching it ensures that the instance is not automatically replaced or scaled in/out during the investigation. This step helps maintain the compromised instance in its current state for analysis.Deregister the instance from any Elastic Load Balancing (ELB) resources:Deregistering the instance from ELB resources ensures that the compromised instance is no longer part of any load balancing pools. This is essential to prevent the instance from receiving new traffic through the load balancer, contributing to the isolation of the compromised instance.C. Use Systems Manager Run Command to invoke scripts that collect volatile data.Systems Manager Run Command allows you to execute commands on EC2 instances without the need for SSH or RDP. This helps collect volatile data without establishing direct connections to the instances.E. Create a snapshot of the compromised EC2 instance's EBS volume for follow-up investigations. Tag the instance with any relevant metadata and incident ticket information.Creating an EBS volume snapshot preserves non-volatile data for forensic purposes, and tagging the instance with relevant information helps with tracking and incident response.Incorrect options:B. Gather any relevant metadata for the compromised EC2 instance. Enable termination protection. Move the instance to an isolation subnet that denies all source and destination traffic. Associate the instance with the subnet to restrict access. Detach the instance from any Auto Scaling groups that the instance is a member of. Deregister the instance from any Elastic Load Balancing (ELB) resources.B is incorrect because once a EC2 instance created, it could not be moved to other subnets. EC2 instances cannot be directly moved to a different subnet after creation. Once an EC2 instance is launched, it is associated with a specific subnet, and that association cannot be changed.D. Establish a Linux SSH or Windows Remote Desktop Protocol (RDP) session to the compromised EC2 instance to invoke scripts that collect volatile data.Option D suggests establishing an SSH or RDP session, which is not desirable when the instance is compromised, and it doesn't use Systems Manager.F. Create a Systems Manager State Manager association to generate an EBS volume snapshot of the compromised EC2 instance. Tag the instance with any relevant metadata and incident ticket information.Option F suggests using Systems Manager State Manager to generate an EBS volume snapshot, but Run Command is more appropriate for invoking scripts during an investigation.
