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

SSL Inspection Requirement:

FortiWeb Cloud provides comprehensive SSL inspection capabilities, allowing it to decrypt and inspect HTTPS traffic for threats. This is a crucial feature for many organizations that need to ensure all traffic, including encrypted traffic, is thoroughly inspected (Option C).

Comparison with AWS WAF:

While AWS WAF with Fortinet managed rules provides robust protection, it might not offer the same level of SSL inspection capabilities as FortiWeb Cloud.

Other Considerations:

Option A (Manual WAF signature updates) is incorrect because FortiWeb Cloud updates signatures automatically.

Option B (PCI 6.6 compliance) is a general requirement for any WAF solution, not specific to choosing FortiWeb Cloud over AWS WAF.

Option D (Traffic inspection for malware) is a feature provided by both FortiWeb Cloud and AWS WAF with Fortinet managed rules.

Understanding Gateway Load Balancer (GWLB):

GWLB is designed to distribute traffic across multiple appliances for both inbound and outbound traffic, providing scalability and high availability.

Traffic Load Balancing:

GWLB can send traffic to multiple FortiGate appliances for load balancing purposes, ensuring efficient use of resources (Option A).

Stateful Processing:

For stateful processing, GWLB ensures that traffic flows (both inbound and outbound) for a given connection are directed to the same FortiGate appliance. This maintains session integrity (Option B).

Preservation and Hashing of Traffic:

Options C and D are incorrect as they suggest incorrect behavior regarding traffic content preservation and hashing for data integrity, which are not primary functions of GWLB.

Zero-day Protection:

FortiWeb VM provides robust protection against zero-day vulnerabilities through advanced security mechanisms and frequent updates from FortiGuard. This ensures that web applications are protected from newly discovered threats that have not yet been patched or recognized by other security systems (Option C).

Advanced WAF Functionality:

FortiWeb VM offers a range of advanced WAF features that go beyond what is typically provided by managed rules for AWS WAF. These include more detailed traffic analysis, customizable rules, machine learning-based threat detection, and comprehensive logging and reporting capabilities (Option D).

Other Options Analysis:

Option A is more relevant to a consumption-based pricing model but not a specific benefit unique to FortiWeb VM over AWS WAF.

Option B is incorrect because both FortiWeb VM and Fortinet Managed Rules for AWS WAF are powered by FortiGuard updates.

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.

Dynamic Address Object Update:

The debug output shows that the IP address of the AWS Windows Server Lab has been updated automatically, indicating that the dynamic address object feature is working as intended. This allows FortiGate to adapt to changes in the IP addresses of AWS instances dynamically (Option A).

SDN Connector Configuration:

The messages in the debug output confirm that the SDN connector is able to retrieve instance information and update the firewall address objects successfully. This implies that the SDN connector is correctly configured and has the necessary permissions (Option C).

Manual Change and Permissions:

Option B is incorrect because while the address object could theoretically be changed manually, this is not inferred from the debug output.

Option D is incorrect because the debug output does not indicate that the AWS user account must have full administrative rights. The required permissions are typically more scoped to specific actions related to SDN.

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.

Implicit Deny Rule:

Similar to traditional firewall rule sets, FortiGate Cloud-Native Firewall (CNF) includes an implicit deny rule at the bottom of each policy set. This means any traffic that does not match an existing rule in the policy set is automatically denied (Option A).

Policy Set Creation:

When a new CNF instance is deployed, a new policy set is created specifically for that instance. This ensures that each CNF instance can have a tailored set of security policies based on the specific needs of the deployment (Option C).

Other Options Analysis:

Option B is incorrect because policy sets do not require manual synchronization; they are applied automatically once configured.

Option D is incorrect as a single CNF instance operates with a single policy set at a time.
