FCSS_EFW_AD-7.4 Exam Dumps - FCSS - Enterprise Firewall 7.4 Administrator

Unlike IPS or antivirus databases,FortiGate does not store a full web filter database locally. Instead, FortiGatequeries FortiGuard (or FortiManager, if configured) dynamicallyto classify and filter web content in real time.

Key points:

●Web filtering works on a cloud-based model:

● When a user requests a website,FortiGate queries FortiGuard servers to check its category and reputation.

● The response is then cached locally for faster lookups on repeated requests.

●No local web filter database version:

● UnlikeIPS and antivirus, which download and store signature updates locally,web filtering relies on cloud-based queries.

● This is whyno database version appears in the GUI.

●Flow mode vs Proxy mode:

● Inproxy mode, FortiGate cancachesome web filter data, improving performance.

● Inflow mode, all queries happen dynamically, with no locally stored database.

The diagnose vpn tunnel list name Hub2Spoke1 command output provides key information about the offloading status of an IPsec VPN tunnel to the Network Processing Unit (NPU).

● npu_flag=20:

● This flag indicates that both inbound and outbound IPsec Security Associations (SAs) have been offloaded to the NPU, meaning the VPN traffic is processed in hardware instead of the CPU.

● npu_rgwy=10.10.2.2 and npu_lgwy=10.10.1.1:

● These IPs represent the remote gateway (rgwy) and local gateway (lgwy), confirming that the tunnel is successfully offloaded.

● npu_selid=1:

● This value means the session selector for the NPU offloaded SA is active.

Since both inbound and outbound SAs are offloaded, the administrator can conclude that the FortiGate NPU is handling IPsec encryption and decryption efficiently, reducing CPU load and improving VPN performance.

In atransparent mode Virtual Domain (VDOM)configuration, FortiGate operates as aLayer 2 bridgerather than performing Layer 3 routing. Theset forward-domain <domain_ID>command is used to control how traffic is forwarded between interfaces within the sametransparent VDOM.

Aforward-domainacts as abroadcast domain, meaning only interfaces with thesame forward-domain IDcan exchange traffic. This setting is commonly used toseparate different VLANs or network segmentswithin the transparent VDOM while still allowing FortiGate to apply security policies.

Use metadata variables to dynamically assign values according to each FortiGate device:Metadata variables in FortiManager allow device-specific configurations to be dynamically assigned without manually configuring each FortiGate. This is especially useful when deploying multiple devices with similar base configurations.

Use provisioning templates and install configuration settings at the device layer:Provisioning templates in FortiManager provide a structured way to configure FortiGate devices. These templates can define interfaces, policies, and settings, ensuring that each device is correctly configured upon deployment.

Add FortiGate devices on FortiManager as model devices, and use ZTP or LTP to connect to FortiGate devices:Zero-Touch Provisioning (ZTP) and Local Touch Provisioning (LTP) help automate the deployment of FortiGate devices. By adding devices as model devices in FortiManager, configurations can be pushed automatically when devices connect for the first time, reducing manual effort.

Whenstandardizing the deployment of FortiGate devices across branchesusing FortiManager, thebest practiceis to usemetadata variables. This allows fordynamic interface configurationwhile maintaining asingle, consistent policy packagefor all branches.

●Metadata variablesin FortiManager enableinterface roles and configurations to be dynamically assignedbased on the specific FortiGate device.

● This ensuresscalabilityandconsistent security policy enforcementacross all branches without manually adjusting interface settings for each device.

● When a new branch FortiGate is deployed, metadata variables automaticallymap to the correct physical interfaces, reducing manual configuration errors.
