NSE6_WCS-7.0 Fortinet NSE 6 - Cloud Security 7.0 for AWS Questions and Answers

AWS GuardDuty Integration:

AWS GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect AWS accounts and workloads. It can generate findings that can be used to create or update firewall rules automatically in FortiGate to enhance security and provide timely protection (Option D).

Integration with FortiGate:

GuardDuty findings can be integrated with FortiGate using automation tools and scripts to create firewall rules dynamically, thereby accelerating the time-to-protection against emerging threats.

Other Options Analysis:

Option A (AWS Firewall Manager) is more suited for managing rules across multiple accounts but not for dynamic threat response.

Option B (AWS Network ACL) provides stateless filtering but does not offer automated rule creation.

Option C (SDN Connector for AWS) helps in integrating SDN capabilities but is not specifically focused on threat-based rule automation.

VPC-Scoped Protection:

When deploying a FortiWeb VM inside a Virtual Private Cloud (VPC), the security and protection it offers are limited to the applications and traffic that pass through that specific VPC. This means that any applications outside this VPC will not benefit from the protection of FortiWeb VM (Option D).

Comparison with FortiWeb Cloud:

FortiWeb Cloud, being a cloud-native WAF-as-a-Service, can protect applications regardless of their VPC location, offering broader and more flexible protection capabilities.

Other Options Analysis:

Option A is incorrect because both FortiWeb VM and FortiWeb Cloud protect against OWASP Top 10 threats.

Option B is incorrect because FortiWeb VM does support zero-day protection.

Option C is incorrect as the performance of FortiWeb VM in applying advanced WAF protection is not inherently slower compared to FortiWeb Cloud.

Web Application Name:

When onboarding a web application to be protected by FortiWeb Cloud, you need to provide a name for the web application. This helps in identifying and managing the application within the FortiWeb Cloud console (Option B).

DNS Records:

To ensure that traffic to your web application is correctly routed through FortiWeb Cloud, you must create DNS records in the domain server that hosts your application. This ensures that requests are directed to FortiWeb Cloud for inspection and protection (Option C).

Other Considerations:

Option A (Waiting for the EC2 instance) is incorrect as it is not a necessary step for onboarding a web application to FortiWeb Cloud.

Option D (Enabling a CDN) is not a mandatory step for onboarding but can be part of a broader strategy for improving performance and protection.

Network Load Balancer:

Deploying a network load balancer ensures that incoming traffic is distributed across multiple web servers, providing high availability and redundancy. This setup helps in managing traffic efficiently and maintaining service uptime even if some servers fail (Option A).

Multiple Availability Zones:

Deploying web servers in multiple availability zones (AZs) enhances fault tolerance and availability. If one AZ goes down, servers in other AZs can continue to handle the traffic, ensuring the web application remains accessible (Option D).

Other Options Analysis:

Option B is incorrect because NAT Gateways are used to provide internet access to instances in private subnets, not to make private addresses reachable from the internet.

Option C is not sufficient on its own for high availability. Adding a route to the default VPC route table forwarding traffic to the internet gateway makes the VPC internet-accessible but does not ensure high availability.

Regional Deployment:

For a global organization with cloud networks in multiple AWS regions, a separate FortiGate Cloud-Native Firewall (CNF) instance is required for each AWS region to provide localized protection and meet compliance requirements. This ensures that each region has its own dedicated NGFW protection tailored to its specific needs (Option B).

Multi-Account Association:

FortiGate CNF supports associating multiple AWS accounts with a single CNF instance. This feature is beneficial for organizations that operate in a multi-account setup, allowing centralized management and security policies across different accounts (Option C).

Other Options Analysis:

Option A is incorrect because AWS Firewall Manager is a different service and is not required to provision a CNF instance.

Option D is incorrect because a single CNF instance cannot protect multiple AWS regions due to regional isolation in AWS.

Traffic Direction through GWLB Endpoint:

The ingress route table directs inbound traffic to the GWLB through a GWLB endpoint (GWLBe). This endpoint is responsible for directing traffic to the Gateway Load Balancer for further processing (Option B).

GENEVE Encapsulation:

The GWLB encapsulates the inbound traffic using the GENEVE protocol. This encapsulated traffic is then sent to FortiGate instances for security inspection. The use of GENEVE ensures that the original traffic context is preserved and can be analyzed by FortiGate (Option D).

Other Options Analysis:

Option A is incorrect because GWLB does not forward traffic without encapsulation in its dedicated subnet.

Option C is incorrect as the inbound traffic is directed to the GWLB endpoint first, not directly to the application subnet.

Cluster Elastic IP Address (EIP) Movement:

During a failover in an active-passive (A-P) cluster, the Elastic IP (EIP) associated with the active FortiGate instance (FGT-1) needs to be moved to the passive instance (FGT-2), which becomes the new active instance. This ensures that the traffic directed to the EIP is now handled by FGT-2 (Option A).

Secondary IP Address Movement:

The secondary IP address on Port2 of the current active instance (FGT-1) is moved to the same port on the new active instance (FGT-2). This step is crucial to ensure seamless network traffic redirection and connectivity for the services relying on that IP address (Option B).

Other Options Analysis:

Option C is incorrect because the static route modification mentioned is not directly related to the failover process described.

Option D is incorrect because no additional route needs to be added to the HA Sync AZ2 subnet route table to forward traffic to the Internet Gateway during a failover.
