Security Fabric

The Fortinet Security Fabric provides an intelligent architecture that interconnects discrete security solutions into an integrated whole to detect, monitor, block, and remediate attacks across the entire attack surface. It delivers broad protection and visibility into every network segment and device, be they hardware, virtual, or cloud based.

  • The physical topology view shows all connected devices, including access layer devices. The logical topology view shows information about the interfaces that each device is connected to.
  • Security rating checks analyze the Security Fabric deployment to identify potential vulnerabilities and highlight best practices to improve the network configuration, deploy new hardware and software, and increase visibility and control of the network.
  • Automation pairs an event trigger with one or more actions to monitor the network and take the designated actions automatically when the Security Fabric detects a threat.
  • Fabric connectors provide integration with multiple SDN, cloud, and partner technology platforms to automate the process of managing dynamic security updates without manual intervention.

Deploy Security Fabric

This recipe provides an example of deploying Security Fabric with three downstream FortiGates connecting to one root FortiGate. To deploy Security Fabric, you need a FortiAnalyzer running firmware version 6.2.

The following shows a sample network topology of three downstream FortiGates (Accounting, Marketing, and Sales) connected to the root FortiGate (Edge).

To configure the root FortiGate (Edge):

  1. Configure interface:
    1. In the root FortiGate (Edge), go to Network > Interfaces.
    2. Edit port16:
      • Set Role to DMZ.
      • For the interface connected to FortiAnalyzer, set the IP/Network Mask to 168.65.2/255.255.255.0 c. Edit port10:
      • Set Role to LAN.
      • For the interface connected to the downstream FortiGate (Accounting), set the IP/Network Mask to

192.168.10.2/255.255.255.0

  1. Edit port11:
  • Set Role to LAN.
  • For the interface connected to the downstream FortiGate (Marketing), set the IP/Network Mask to 168.200.2/255.255.255.0
  1. Configure Security Fabric:
  2. In the root FortiGate (Edge), go to Security Fabric > Settings. l Enable FortiGate Telemetry.
    • Set a Group name, such as Office-Security-Fabric.
    • Add port10 and port11 to FortiTelemetry enabled interfaces.

After FortiGate Telemetry is enabled, FortiAnalyzer automatically enables Logging and Upload Option is set to Real Time.

  1. Set IP address to the FortiAnalyzer IP 168.65.10.
  2. Select Test Connectivity.

A warning message indicates that the FortiGate is not authorized on the FortiAnalyzer. The authorization is configured in a later step on the FortiAnalyzer.

  1. Create a policy to allow the downstream FortiGate (Accounting) to access the FortiAnalyzer:
  2. In the root FortiGate (Edge), go to Policy & Objects > Addresses.
