Kevin Ryan has been working as a cloud security engineer over the past 2 years in a multinational company, which uses AWS-based cloud services. He launched an EC2 instance with Amazon Linux AMI. By disabling password-based remote logins, Kevin wants to eliminate all possible loopholes through which an attacker can exploit a user account remotely. To disable password-based remote logins, using the text editor, Kevin opened the /etc/ssh/sshd_config file and found the #PermitRootLogin yes line. Which of the following command lines should Kevin use to change the #PermitRootLogin yes line to disable password-based remote logins?
- A. PermitRootLogin without./password
- B. PermitRootLogin without./password/disable
- C. PermitRootLogin without-password/disable
- D. PermitRootLogin without-password
正解：D
解説：
To disable password-based remote logins for the root account on an EC2 instance running Amazon Linux AMI, Kevin should modify the SSH configuration as follows:
* Open SSH Configuration: Using a text editor, open the /etc/ssh/sshd_config file.
* Find PermitRootLogin Directive: Locate the line #PermitRootLogin yes. The # indicates that the line is commented out.
* Modify the Directive: Change the line to PermitRootLogin without-password. This setting allows root login using authentication methods other than passwords, such as SSH keys, while disabling password-based root logins.
* Save and Close: Save the changes to the sshd_config file and exit the text editor.
* Restart SSH Service: To apply the changes, restart the SSH service by running sudo service sshd restart or sudo systemctl restart sshd, depending on the system's init system.

Rebecca Mader has been working as a cloud security engineer in an IT company located in Detroit, Michigan.
Her organization uses AWS cloud-based services. An application is launched by a developer on an EC2 instance that needs access to the S3 bucket (photos). Rebecca created a get-pics service role and attached it to the EC2 instance. This service role comprises a permission policy that allows read-only access to the S3 bucket and a trust policy that allows the instance to assume the role and retrieve temporary credentials. The application uses the temporary credentials of the role to access the photo bucket when it runs on the instance.
Does the developer need to share or manage credentials or does the admin need to grant permission to the developer to access the photo bucket?
- A. Yes, the developer should share or manage credentials and the admin should grant permission to the developer to access the photo bucket
- B. No, the developer never has to share or manage credentials, but the admin has to grant permission to the developer to access the photo bucket
- C. Yes, the developer has to share or manage credentials, but the admin does not have to grant permission to the developer to access the photo bucket
- D. No, the developer never has to share or manage credentials and the admin does not have to grant permission to the developer to access the photo bucket
正解：D
解説：
* AWS IAM Roles: AWS Identity and Access Management (IAM) roles allow for permissions to be assigned to AWS resources without the use of static credentials. Roles provide temporary credentials that are automatically rotated.
* Service Role: The 'get-pics' service role created by Rebecca includes a permission policy for read-only access to the S3 bucket and a trust policy that allows the EC2 instance to assume the role.
* Temporary Credentials: When the application runs on the EC2 instance, it uses the temporary credentials provided by the role to access the S3 bucket. These credentials are dynamically provided and do not require developer management.
* Developer and Admin Roles: Since the EC2 instance has the necessary permissions through the service role, the developer does not need to manage credentials. Similarly, the admin does not need to grant explicit permission to the developer because the permissions are already encapsulated within the role.
* Security Best Practices: This approach adheres to AWS security best practices by avoiding the sharing of static credentials and minimizing the need for manual credential management.

A security incident has occurred within an organization's AWS environment. A cloud forensic investigation procedure is initiated for the acquisition of forensic evidence from the compromised EC2 instances. However, it is essential to abide by the data privacy laws while provisioning any forensic instance and sending it for analysis. What can the organization do initially to avoid the legal implications of moving data between two AWS regions for analysis?
- A. Create evidence volume from the snapshot
- B. Provision and launch a forensic workstation
- C. Mount the evidence volume on the forensic workstation
- D. Attach the evidence volume to the forensic workstation
正解：A
解説：
When dealing with a security incident in an AWS environment, it's crucial to handle forensic evidence in a way that complies with data privacy laws. The initial step to avoid legal implications when moving data between AWS regions for analysis is to create an evidence volume from the snapshot of the compromised EC2 instances.
* Snapshot Creation: Take a snapshot of the compromised EC2 instance's EBS volume. This snapshot captures the state of the volume at a point in time and serves as forensic evidence.
* Evidence Volume Creation: Create a new EBS volume from the snapshot within the same AWS region to avoid cross-regional data transfer issues.
* Forensic Workstation Provisioning: Provision a forensic workstation within the same region where the evidence volume is located.
* Evidence Volume Attachment: Attach the newly created evidence volume to the forensic workstation for analysis.
References:Creating an evidence volume from a snapshot is a recommended practice in AWS forensics. It ensures that the integrity of the data is maintained and that the evidence is handled in compliance with legal requirements12. This approach allows for the preservation, acquisition, and analysis of data without violating data privacy laws that may apply when transferring data across regions12.
