Zero-trust tags are critical in implementing zero-trust network access (ZTNA) policies. Here are the two key advantages of using zero-trust tags:

Access Control (Allow or Deny):

Zero-trust tags can be used to define policies that either allow or deny access to specific network resources based on the tag associated with the user or device.

This granular control ensures that only authorized users or devices with the appropriate tags can access sensitive resources, thereby enhancing security.

Determining Security Posture:

Zero-trust tags can be utilized to assess and determine the security posture of an endpoint.

Based on the assigned tags, FortiSASE can evaluate the device's compliance with security policies, such as antivirus status, patch levels, and configuration settings.

Devices that do not meet the required security posture can be restricted from accessing the network or given limited access.

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.

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) 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.

For a customer looking to upgrade their legacy on-premises proxy to a cloud-based proxy for a hybrid network, the combination of Secure Web Gateway (SWG) and Inline Cloud Access Security Broker (CASB) features in FortiSASE will provide the necessary capabilities.

Secure Web Gateway (SWG):

SWG provides comprehensive web security by inspecting and filtering web traffic to protect against web-based threats.

It ensures that all web traffic, whether originating from on-premises or remote locations, is inspected and secured by the cloud-based proxy.

Inline Cloud Access Security Broker (CASB):

CASB enhances security by providing visibility and control over cloud applications and services.

Inline CASB integrates with SWG to enforce security policies for cloud application usage, preventing unauthorized access and data leakage.

FortiOS 7.2 Administration Guide: Details on SWG and CASB features.

FortiSASE 23.2 Documentation: Explains how SWG and inline-CASB are used in cloud-based proxy solutions.

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 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.

FortiSASE uses the following components for application control to act as an inline-CASB (Cloud Access Security Broker):

SSL Deep Inspection:

SSL deep inspection is essential for decrypting and inspecting HTTPS traffic to identify and control applications and data transfers within encrypted traffic.

This allows FortiSASE to enforce security policies on SSL/TLS encrypted traffic, providing visibility and control over cloud applications.

Web Filter with Inline-CASB:

The web filter component integrates with inline-CASB to monitor and control access to cloud applications based on predefined security policies.

This combination provides granular control over cloud application usage, ensuring compliance with security policies and preventing unauthorized data transfers.

The Secure Web Gateway (SWG) policy is used to control traffic between the FortiClient endpoint and FortiSASE for secure internet access. SWG provides comprehensive web security by enforcing policies that manage and monitor user access to the internet.

Secure Web Gateway (SWG) Policy:

SWG policies are designed to protect users from web-based threats and enforce acceptable use policies.

These policies control and monitor user traffic to and from the internet, ensuring that security protocols are followed.

Traffic Control:

The SWG policy intercepts all web traffic, inspects it, and applies security rules before allowing or blocking access.

This policy type is crucial for providing secure internet access to users connecting through FortiSASE.

FortiSASE hides user information when viewing and analyzing logs by hashing data using salt. This approach ensures that sensitive user information is obfuscated, enhancing privacy and security.

Hashing Data with Salt:

Hashing data involves converting it into a fixed-size string of characters, which is typically a hash value.

Salting adds random data to the input of the hash function, ensuring that even identical inputs produce different hash values.

This method provides enhanced security by making it more difficult to reverse-engineer the original data from the hash value.

Security and Privacy:

Using salted hashes ensures that user information remains secure and private when stored or analyzed in logs.

This technique is widely used in security systems to protect sensitive data from unauthorized access.
