312-40 Exam Dumps - EC-Council Certified Cloud Security Engineer (CCSE)

In the event of a security issue on the cloud, such as a DDoS attack or illegal activities, Incident Handlers are typically the first responders. Their role is to manage the initial response to the incident, which includes identifying, assessing, and mitigating the threat to reduce damage and recover from the attack.

Here’s the role of Incident Handlers as first responders:

Incident Identification: They quickly identify the nature and scope of the incident.

Initial Response: Incident Handlers take immediate action to contain and control the situation to prevent further damage.

Communication: They communicate with internal stakeholders and may coordinate with external parties like law enforcement if necessary.

Evidence Preservation: Incident Handlers work to preserve evidence for forensic analysis and legal proceedings.

Recovery and Documentation: They assist in the recovery process and document all actions taken for future reference and analysis.

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.

References:The PermitRootLogin without-password directive in the SSH configuration file is used to enhance security by preventing password-based authentication for the root user, which is a common target for brute force attacks. Instead, it requires more secure methods like SSH key pairs for authentication. This change is part of best practices for securing SSH access to Linux servers.

Amazon AppStream 2.0 is a fully managed application streaming service that allows users to access desktop applications from anywhere, making it the service that enabled Sandra to access her office laptop applications remotely. Here’s how it works:

Application Hosting: AppStream 2.0 hosts desktop applications on AWS and streams them to a web browser or a connected device.

Secure Access: Users can access these applications securely from any location, as the service provides a secure streaming session.

Resource Optimization: It eliminates the need for high-end user hardware since the processing is done on AWS servers.

Central Management: The organization can manage applications centrally, which simplifies software updates and security.

Integration: AppStream 2.0 integrates with existing identity providers and supports standard security protocols.

Service Level Agreement (SLA): An SLA is a contract between a service provider and the customer that specifies, usually in measurable terms, what services the service provider will furnish1.

Security Standards in SLAs: SLAs often include security standards that the service provider agrees to maintain. This can cover various aspects such as data encryption, access controls, and incident response times1.

Data Compliance: The SLA can also define compliance with relevant regulations and standards, ensuring that the service provider adheres to laws such as GDPR, HIPAA, or industry-specific guidelines2.

Alignment with Business Needs: By clearly stating the security measures and compliance standards, an SLA helps ensure that the cloud services align with the multinational company’s business needs and regulatory requirements1.

Other Options: While service agreements and contracts may contain similar terms, the term “Service Level Agreement” is specifically used in the context of IT services to define performance and quality metrics, making it the most appropriate choice for defining security standards and compliance in cloud services1.

AWS Certificate Manager (ACM) is the service that enables an AWS security expert to manage SSL/TLS certificates provided by AWS or an external certificate authority. It allows the deployment of the certificate on AWS services such as an Application Load Balancer (ALB) and also handles the renewal and rotation of certificates.

Here’s how ACM would be used for the web application:

Certificate Provisioning: The security expert can import an SSL/TLS certificate issued by an external certificate authority into ACM.

Integration with ALB: ACM integrates with ALB, allowing the certificate to be easily deployed to encrypt the application at the edge.

Automatic Renewal: ACM can be configured to automatically renew certificates provided by AWS. For certificates from external authorities, the expert can manually import a new certificate before the old one expires.

Yearly Rotation: While ACM does not automatically rotate externally provided certificates, it simplifies the process of replacing them by allowing the expert to import new certificates as needed.
