Fortinet FCSS_SASE_AD-23 Exam Questions

To resolve internal hostnames using internal DNS servers for remotely connected endpoints, the following two components must be configured on FortiSASE:

Split DNS Rules:

Split DNS allows the configuration of specific DNS queries to be directed to internal DNS servers instead of public DNS servers.

This ensures that internal hostnames are resolved using the organization's internal DNS infrastructure, maintaining privacy and accuracy for internal network resources.

Split Tunneling Destinations:

Split tunneling allows specific traffic (such as DNS queries for internal domains) to be routed through the VPN tunnel while other traffic is sent directly to the internet.

By configuring split tunneling destinations, you can ensure that DNS queries for internal hostnames are directed through the VPN to the internal DNS servers.

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.'

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.
