The reason for the ping failures is due to the quick mode selectors restricting the subnet. Quick mode selectors define the IP ranges and protocols that are allowed through the VPN tunnel, and if they are not configured correctly, traffic to certain subnets can be blocked.

Quick Mode Selectors:

Quick mode selectors specify the source and destination subnets that are allowed to communicate through the VPN tunnel.

If the selectors do not include the subnet of the webserver (192.168.10.0/24), then the traffic will be restricted, and the ping will fail.

Diagnostic Output:

The diagnostic output shows the VPN configuration details, but it is important to check the quick mode selectors to ensure that the necessary subnets are included.

If the quick mode selectors are too restrictive, they will prevent traffic to and from the specified subnets.

Configuration Check:

Verify the quick mode selectors on both the FortiSASE and FortiGate hub to ensure they match and include the subnet of the webserver.

Adjust the selectors to allow the necessary subnets for successful communication.

Zero Trust Network Access (ZTNA) private access provides the most efficient and secure method for remote users to access a TCP-based application hosted on a private web server. ZTNA ensures that only authenticated and authorized users can access specific applications based on predefined policies, enhancing security and access control.

Zero Trust Network Access (ZTNA):

ZTNA operates on the principle of 'never trust, always verify,' continuously verifying user identity and device security posture before granting access.

It provides secure and granular access to specific applications, ensuring that remote users can securely access the TCP-based application hosted on the private web server.

Secure and Efficient Access:

ZTNA private access allows remote users to connect directly to the application without needing a full VPN tunnel, reducing latency and improving performance.

It ensures that only authorized users can access the application, providing robust security controls.

FortiOS 7.2 Administration Guide: Provides detailed information on ZTNA and its deployment use cases.

FortiSASE 23.2 Documentation: Explains how ZTNA can be used to provide secure access to private applications for remote users.

Based on the provided exhibits and the configuration details, the reason why users are still able to download the eicar.com-zip file despite having an antivirus profile applied is due to the Web Filter allowing the traffic. Here is the step-by-step detailed explanation:

Web Filtering Logs Analysis:

The logs show that the traffic to the destination port 443 (which is HTTPS) is allowed and the security event triggered is Web Filter.

The log details indicate that the URL belongs to an allowed category in the policy and thus, the traffic is permitted by the Web Filter.

Security Profile Group Configuration:

The Web Filter with Inline-CASB section indicates that the site www.eicar.org is being monitored (93 occurrences) and not blocked.

Since the Web Filter is set to allow traffic from this site, the antivirus profile will not block it because the Web Filter decision takes precedence.

Antivirus Profile Configuration:

Although the antivirus profile is configured, the logs do not show any antivirus actions being triggered. This indicates that the web filter is overriding the antivirus action.

Policy Configuration:

The policy named 'Web Traffic' shows that it has logging enabled and is set to accept traffic.

The profile group 'SIA' applied to this policy includes both Web Filter and Antivirus settings. However, since the Web Filter is allowing the traffic, the antivirus profile does not get the chance to inspect it.

To block all video and audio application traffic while granting access to videos from CNN, you need to configure an application override action in the Application Control with Inline-CASB. Here is the step-by-step detailed explanation:

Application Control Configuration:

Application Control is used to identify and manage application traffic based on predefined or custom application signatures.

Inline-CASB (Cloud Access Security Broker) extends these capabilities by allowing more granular control over cloud applications.

Blocking Video and Audio Applications:

To block all video and audio application traffic, you can create a policy within Application Control to deny all categories related to video and audio streaming.

Granting Access to Specific Videos (CNN):

To allow access to videos from CNN specifically, you must create an override rule within the same Application Control profile.

The override action 'Exempt' ensures that traffic to specified URLs (such as those from CNN) is not subjected to the blocking rules set for other video and audio traffic.

Configuration Steps:

Navigate to the Application Control profile in the FortiSASE interface.

Set the application categories related to video and audio streaming to 'Block.'

Add a new override entry for CNN video traffic and set the action to 'Exempt.'

When remote users connected to FortiSASE require access to internal resources on Branch-2, the following process occurs:

SD-WAN Capability:

FortiSASE leverages SD-WAN to optimize traffic routing based on performance metrics and priorities.

In the priority settings, HUB-1 is configured with the highest priority (P1), whereas HUB-2 has a lower priority (P2).

Traffic Routing Decision:

FortiSASE evaluates the available hubs (HUB-1 and HUB-2) and selects HUB-1 due to its highest priority setting.

Once the traffic reaches HUB-1, it is then routed to the appropriate branch based on internal routing policies.

Branch-2 Access:

Since HUB-1 has the highest priority, FortiSASE directs the traffic to HUB-1.

HUB-1 then routes the traffic to Branch-2, providing the remote users access to the internal resources.

FortiOS 7.2 Administration Guide: Details on SD-WAN configurations and priority settings.

FortiSASE 23.2 Documentation: Explains how FortiSASE integrates with SD-WAN to route traffic based on defined priorities and performance metrics.

There are two deployment methods used to connect a FortiExtender as a FortiSASE LAN extension:

Connect FortiExtender to FortiSASE using FortiZTP:

FortiZero Touch Provisioning (FortiZTP) simplifies the deployment process by allowing FortiExtender to automatically connect and configure itself with FortiSASE.

This method requires minimal manual configuration, making it efficient for large-scale deployments.

Enter the FortiSASE domain name in the FortiExtender GUI as a static discovery server:

Manually configuring the FortiSASE domain name in the FortiExtender GUI allows the extender to discover and connect to the FortiSASE infrastructure.

This static discovery method ensures that FortiExtender can establish a connection with FortiSASE using the provided domain name.
