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

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.

Windows Firewall Blocking Traffic:

The firewall on the Windows VM might be configured to block incoming ICMP traffic (ping requests). By default, Windows Firewall is set to block ICMP traffic, which could be a reason for the connectivity issue (Option A).

Security Group Configuration:

AWS Security Groups act as virtual firewalls for instances. If there is no rule allowing ICMP traffic in the security group attached to the Windows server, the ping requests from FortiGate will be blocked. An inbound allow ICMP rule must be added to the security group to permit this traffic (Option D).

Other Options Analysis:

Option B is incorrect because the default AWS Network Access Control List (NACL) allows all inbound and outbound traffic.

Option C is incorrect as AWS does allow ICMP traffic between subnets if properly configured with Security Groups and NACLs.

Enhanced Redundancy:

Deploying an active-passive (A-P) FortiGate cluster across two availability zones (AZs) provides enhanced redundancy by ensuring that if one AZ fails, the other can take over, maintaining high availability and uptime.

IP Addressing and Subnetting:

One of the major differences when deploying across different AZs compared to the same AZ is that IP addressing and subnetting are not shared between the instances. Each AZ operates independently with its own set of subnets and IP addresses, which must be managed separately (Option D).

Other Options Analysis:

Option A is incorrect because the FortiGate devices in an A-P setup do not act as a single logical instance; they operate in a failover setup.

Option B is incorrect because secondary IP address configuration is used in both single AZ and multi-AZ deployments.

Option C is incorrect because the number of subnets required is typically more when deploying across multiple AZs for redundancy.

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.

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.

Remote Access to FortiGate VM:

The FortiCloud portal allows users to remotely access their FortiGate VM instances. This is particularly useful for managing and configuring instances without needing direct network access (Option A).

FortiFlex Portal Access:

The FortiFlex portal is a feature that becomes available only after purchasing a FortiFlex license and registering it on FortiCare. This portal provides additional functionalities and services related to FortiFlex (Option C).

IAM Permissions:

Option B is incorrect because the Identity and Access Management (IAM) permissions in the FortiCloud portal do not require writing JSON scripts; they can be managed through the portal interface.

Subscription to Cloud Services:

Option D is incorrect because FortiCloud provides access to services beyond those subscribed through the AWS marketplace, including services directly offered by Fortinet.

Invalid Credentials:

The debug output shows an "AuthFailure" error, indicating that AWS was not able to validate the provided access credentials. This usually points to incorrect or invalid AWS access or secret keys configured in the AWS Lab SDN connector (Option C).

Clock Skew:

Another common reason for authentication failures in AWS API calls is a clock skew between the FortiGate device and AWS. AWS requires that the system time of the client making the API call is synchronized with its own time, within a small margin. If there is a significant time difference, AWS will reject the credentials (Option B).

Other Options Analysis:

Option A is incorrect because the AWS API supports XML version 1.0.

Option D is incorrect as the error message does not indicate an issue with connecting on port 401.

Option E is incorrect because the error is related to authentication, not the absence of instances.
