QUESTION: 21

Trevor Noah works as a cloud security engineer in an IT company located in Seattle, Washington. Trevor has implemented a disaster recovery approach that runs a scaled-down version of a fully functional environment in the cloud. This method is most suitable for his organization's core business-critical functions and solutions that require the RTO and RPO to be within minutes. Based on the given information, which of the following disaster recovery approach is implemented by Trevor?

Backup and Restore
Multi-Cloud Option
Pilot Light approach
Warm Standby

Answer(s): D

Explanation:

The Warm Standby approach in disaster recovery involves running a scaled-down version of a fully functional environment in the cloud. This method is activated quickly in case of a disaster, ensuring that the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are within minutes.
1. Scaled-Down Environment: A smaller version of the production environment is always running in the cloud. This includes a minimal number of resources required to keep the application operational12.

2. Quick Activation: In the event of a disaster, the warm standby environment can be quickly scaled up to handle the full production load12.

3. RTO and RPO: The warm standby approach is designed to achieve an RTO and RPO within minutes, which is essential for business-critical functions12.

4. Business Continuity: This approach ensures that core business functions continue to operate with minimal disruption during and after a disaster12.

Reference:

Warm Standby is a disaster recovery strategy that provides a balance between cost and downtime. It is less expensive than a fully replicated environment but offers a faster recovery time than cold or pilot light approaches12. This makes it suitable for organizations that need to ensure high availability and quick recovery for their critical systems.

QUESTION: 22

You are the manager of a cloud-based security platform that offers critical services to government agencies and private companies. One morning, your team receives an alert from the platform's intrusion detection system indicating that there has been a potential breach in the system. As the manager, which tool you will use for viewing and monitoring the sensitive data by scanning storage systems and reviewing the access rights to critical resources via a single centralized dashboard?

Google Cloud Security Command Center
Google Cloud Security Scanner
Cloud Identity and Access Management (IAM)
Google Cloud Armor

Answer(s): A

Explanation:

The Google Cloud Security Command Center (Cloud SCC) is the tool designed to provide a centralized dashboard for viewing and monitoring sensitive data, scanning storage systems, and reviewing access rights to critical resources.

1. Centralized Dashboard: Cloud SCC offers a comprehensive view of the security status of your resources in Google Cloud, across all your projects and services1.

2. Sensitive Data Scanning: It has capabilities for scanning storage systems to identify sensitive data, such as personally identifiable information (PII), and can provide insights into where this data is stored1.

3. Access Rights Review: Cloud SCC allows you to review who has access to your critical resources and whether any policies or permissions should be adjusted to enhance security1.

4. Alerts and Incident Response: In the event of a potential breach, Cloud SCC can help identify the affected resources and assist in the investigation and response process1.

Reference:

Google Cloud Security Command Center is a security management and data risk platform for Google Cloud that helps you prevent, detect, and respond to threats from a single pane of glass. It provides security insights and features like asset inventory, discovery, search, and management; vulnerability and threat detection; and compliance monitoring to protect your services and applications on Google Cloud1.

QUESTION: 23

An organization, PARADIGM PlayStation, moved its infrastructure to a cloud as a security practice. It established an incident response team to monitor the hosted websites for security issues.
While examining network access logs using SIEM, the incident response team came across some incidents that suggested that one of their websites was targeted by attackers and they successfully performed an SQL injection attack.

Subsequently, the incident response team made the website and database server offline. In which of the following steps of the incident response lifecycle, the incident team determined to make that decision?

Analysis
Containment
Coordination and information sharing
Post-mortem

Answer(s): B

Explanation:

The decision to take the website and database server offline falls under the Containment phase of the incident response lifecycle. Here's how the process typically unfolds:
1. Detection: The incident response team detects a potential security breach, such as an SQL injection attack, through network access logs using SIEM.

2. Analysis: The team analyzes the incident to confirm the breach and understand its scope and impact.

3. Containment: Once confirmed, the team moves to contain the incident to prevent further damage. This includes making the affected website and database server offline to stop the attack from spreading or causing more harm1.

4. Eradication and Recovery: After containment, the team works on eradicating the threat and recovering the systems to normal operation.

5. Post-Incident Activity: Finally, the team conducts a post-mortem analysis to learn from the incident and improve future response efforts.

Reference:

The containment phase is critical in incident response as it aims to limit the damage of the security incident and isolate affected systems to prevent the spread of the attack12. Taking systems offline is a common containment strategy to ensure that attackers can no longer access the compromised systems1.

QUESTION: 24

Global SciTech Pvt. Ltd. is an IT company that develops healthcare-related software. Using an incident detection system (IDS) and antivirus software, the incident response team of the organization has observed that attackers are targeting the organizational network to gain access to the resources in the on-premises environment. Therefore, their team of cloud security engineers met with a cloud service provider to discuss the various security provisions offered by the cloud service provider.
While discussing the security of the organization's virtual machine in the cloud environment, the cloud service provider stated that the Network Security Groups (NSGs) will secure the VM by allowing or denying network traffic to VM instances in a virtual network based on inbound and outbound security rules.
Which of the following cloud service provider filters the VM network traffic in a virtual network using NSGs?

IBM
AWS
Azure
Google

Answer(s): C

Explanation:

Network Security Groups (NSGs) are used in Azure to filter network traffic to and from Azure resources within an Azure Virtual Network (VNet). NSGs contain security rules that allow or deny inbound and outbound network traffic based on several parameters such as protocol, source and destination IP address, port number, and direction (inbound or outbound).

1. NSG Functionality: NSGs function as a firewall for VM instances, controlling both inbound and outbound traffic at the network interface, VM, and subnet level1.

2. Security Rules: They consist of security rules that specify source and destination, port, and protocol to filter traffic1.

3. Traffic Control: By setting appropriate rules, NSGs help secure VMs from unauthorized access and ensure that only allowed traffic can flow to and from the VM1.

4. Azure Specific: This feature is specific to Azure and is not offered by IBM, AWS, or Google

Cloud in the same manner1.

Reference:

NSGs are a key component of Azure's networking capabilities, providing a way to control access to VMs, services, and subnets, and are an integral part of Azure's security infrastructure1.
