FCSS_SASE_AD-23 FCSS FortiSASE 23 Administrator Questions and Answers

The unusually high number of unknown applications by category in the daily report for application usage can be attributed to the following reasons:

Certificate Inspection is not being used to scan application traffic:

Without certificate inspection, encrypted traffic cannot be adequately analyzed, leading to a higher number of unknown applications.

Certificate inspection allows the FortiSASE to decrypt and inspect HTTPS traffic, identifying applications correctly.

Deep Inspection is not being used to scan traffic:

Deep inspection goes beyond basic traffic analysis, performing thorough examination of packet contents to identify applications accurately.

If deep inspection is not enabled, many applications may go unrecognized and categorized as unknown.

Onboarding a Secure Web Gateway (SWG) endpoint involves several components to ensure secure and effective integration with FortiSASE. Two key components are the FortiSASE CA certificate and the proxy auto-configuration (PAC) file.

FortiSASE CA Certificate:

The FortiSASE CA certificate is essential for establishing trust between the endpoint and the FortiSASE infrastructure.

It ensures that the endpoint can securely communicate with FortiSASE services and inspect SSL/TLS traffic.

Proxy Auto-Configuration (PAC) File:

The PAC file is used to configure the endpoint to direct web traffic through the FortiSASE proxy.

It provides instructions on how to route traffic, ensuring that all web requests are properly inspected and filtered by FortiSASE.

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.

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

In the user connection monitor, the random characters shown for the username indicate that log anonymization is enabled. Log anonymization is a feature that hides the actual user information in the logs for privacy and security reasons. To display proper user information, you need to disable log anonymization.

Log Anonymization:

When log anonymization is turned on, the actual usernames are replaced with random characters to protect user privacy.

This feature can be beneficial in certain environments but can cause issues when detailed user monitoring is required.

Disabling Log Anonymization:

Navigate to the FortiSASE settings.

Locate the log settings section.

Disable the log anonymization feature to ensure that actual usernames are displayed in the logs and user connection monitors.

Zero Trust Network Access (ZTNA) is the FortiSASE feature that ensures least-privileged user access to all applications. ZTNA operates on the principle of "never trust, always verify," providing secure access based on the identity of users and devices, regardless of their location.

Zero Trust Network Access (ZTNA):

ZTNA ensures that only authenticated and authorized users and devices can access applications.

It applies the principle of least privilege by granting access only to the resources required by the user, minimizing the potential for unauthorized access.

Implementation:

ZTNA continuously verifies user and device trustworthiness and enforces granular access control policies.

This approach enhances security by reducing the attack surface and limiting lateral movement within the network.

FortiSASE 23.2 Documentation: Explains the implementation and benefits of ZTNA within the FortiSASE environment.

FortiSASE brings the following advantages to businesses with multiple branch offices:

Centralized Management for Simplified Administration:

FortiSASE provides a centralized management platform that allows administrators to manage security policies, configurations, and monitoring from a single interface.

This simplifies the administration and reduces the complexity of managing multiple branch offices.

Eliminates the Need for On-Premises Firewalls:

FortiSASE enables secure access to the internet and cloud applications without requiring dedicated on-premises firewalls at each branch office.

This reduces hardware costs and simplifies network architecture, as security functions are handled by the cloud-based FortiSASE solution.
