NSE4 - FortiGate Infrastructure

In this 2-day class, you will learn advanced FortiGate networking and security. Topics include features commonly in complex or larger enterprise/MSSP networks, such as advanced routing, transparent mode, redundant infrastructure, advanced IPsec VPN, IPS, SSO, data leak prevention, diagnostics, and fine-tuning performance.

Course overview

  • After completing these courses, you will be able to:

    • Deploy FortiGate devices as an HA cluster for fault-tolerance & high performance
    • Inspect traffic transparently, forwarding as a Layer 2 device
    • Manage FortiGate device's route table
    • Route packets using policy-based and static routes for multi-path and load-balance deployments
    • Connect virtual domains (VDOMs) without packets leaving FortiGate
    • Implement a meshed / partially redundant VPN
    • Diagnose failed IKE exchanges
    • Fight hacking & denial of service (DoS)

    • Understand encryption functions and certificates
    • Defend against data leaks by identifying files with sensitive data, and blocking them from leaving your private network
    • Diagnose and correct common problems
    • Optimize performance by configuring to leverage ASIC acceleration chips, such as CP or NPs, instead of only the CPU resources
    • Implement IPv6 and hybrid IPv4-IPv6 networks
  • Routing
  • Software-Defined WAN (SD-WAN)
  • Layer 2 Switching
  • Virtual Domains
  • Site-to-Site IPSec VPN
