FCSS_SASE_AD-23 FCSS FortiSASE 23 Administrator Questions and Answers

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.

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.

FortiSASE supports zero trust network access (ZTNA) principles by identifying attributes on the endpoint for security posture checks. ZTNA principles require continuous verification of user and device credentials, as well as their security posture, before granting access to network resources.

Security Posture Check:

FortiSASE can evaluate the security posture of endpoints by checking for compliance with security policies, such as antivirus status, patch levels, and configuration settings.

This ensures that only compliant and secure devices are granted access to the network.

Zero Trust Network Access (ZTNA):

ZTNA is based on the principle of "never trust, always verify," which requires continuous assessment of user and device trustworthiness.

FortiSASE plays a crucial role in implementing ZTNA by performing these security posture checks and enforcing access control policies.

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 sitewww.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.

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.

When configuring FortiSASE Secure Private Access (SPA) with SD-WAN integration, establishing a routing adjacency between FortiSASE and the FortiGate SD-WAN hub requires the use of the Border Gateway Protocol (BGP).

BGP (Border Gateway Protocol):

BGP is widely used for establishing routing adjacencies between different networks, particularly in SD-WAN environments.

It provides scalability and flexibility in managing dynamic routing between FortiSASE and the FortiGate SD-WAN hub.

Routing Adjacency:

BGP enables the exchange of routing information between FortiSASE and the FortiGate SD-WAN hub.

This ensures optimal routing paths and efficient traffic management across the hybrid network.
