C.   zero trust network access (ZTNA)

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.

C.   zero trust network access (ZTNA) private access

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.

A.   Zero-trust tags can be used to allow or deny access to network resources

B.   Zero-trust tags can determine the security posture of an endpoint.

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.

FortiOS 7.2 Administration Guide: Provides detailed information on configuring and using zero-trust tags for access control and security posture assessment.
FortiSASE 23.2 Documentation: Explains how zero-trust tags are implemented and used within the FortiSASE environment for enhancing security and compliance.

A.   Add the FortiGate IP address in the secure private access configuration on FortiSASE.

B.   Use the FortiClient EMS cloud connector on the corporate FortiGate to connect to FortiSASE

C.   Register FortiGate and FortiSASE under the same FortiCloud account.

To configure a Secure Private Access (SPA) solution to share endpoint information between FortiSASE and a corporate FortiGate, you need to take the following steps:

Add the FortiGate IP address in the secure private access configuration on FortiSASE:

This step allows FortiSASE to recognize and establish a connection with the corporate FortiGate.

Use the FortiClient EMS cloud connector on the corporate FortiGate to connect to FortiSASE:

The EMS (Endpoint Management Server) cloud connector facilitates the integration between FortiClient endpoints and FortiSASE, enabling seamless sharing of endpoint information.

Register FortiGate and FortiSASE under the same FortiCloud account:

By registering both FortiGate and FortiSASE under the same FortiCloud account, you ensure centralized management and synchronization of configurations and policies.

B.   SSL deep inspection

D.   Web filter with inline-CASB

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.

B.   Split DNS rules

C.   Split tunnelling destinations

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.

FortiOS 7.2 Administration Guide: Provides details on configuring split DNS and split tunneling for VPN clients.

FortiSASE 23.2 Documentation: Explains the implementation and configuration of split DNS and split tunneling for securely resolving internal hostnames.

A.   Vulnerability scan

B.   SSL inspection

D.   Web filter

When deploying FortiSASE agent-based clients, several features are available that are not typically available with an agentless solution. These features enhance the security and management capabilities for endpoints.

Vulnerability Scan:

Agent-based clients can perform vulnerability scans on endpoints to identify and remediate security weaknesses.

This proactive approach helps to ensure that endpoints are secure and compliant with security policies.

SSL Inspection:

Agent-based clients can perform SSL inspection to decrypt and inspect encrypted traffic for threats.

This feature is critical for detecting malicious activities hidden within SSL/TLS encrypted traffic.

Web Filter:

Web filtering is a key feature available with agent-based clients, allowing administrators to control and monitor web access.

This feature helps enforce acceptable use policies and protect users from web-based threats.
