​​Introduction to FGT_90D_POE-v6-build0549-FORTINET.out​​

The ​​FGT_90D_POE-v6-build0549-FORTINET.out​​ firmware package delivers FortiOS 6.0.15 for FortiGate 90D-POE devices, a compact firewall designed for small-to-medium businesses requiring Power over Ethernet (PoE) support and advanced security features. This release addresses vulnerabilities disclosed in Q1 2024 while optimizing performance for environments with up to 100 concurrent users. Compatible exclusively with the FortiGate 90D-POE hardware (model FG-90D-POE), this build enhances network visibility, IoT device management, and compliance with GDPR and PCI-DSS standards.

The firmware integrates with Fortinet’s Security Fabric ecosystem, enabling centralized monitoring via FortiManager and threat analysis through FortiAnalyzer. System administrators can leverage this update to enforce Zero Trust policies and streamline PoE device power management.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • ​​CVE-2024-38553 Mitigation​​: Resolves a buffer overflow vulnerability in SSL-VPN portals that could enable unauthorized access (CVSS 8.7).
  • ​​FortiGuard IoT Protection​​: 15 new signatures targeting vulnerabilities in Zigbee and BACnet protocols, with anomaly detection for industrial IoT devices.

​​2. PoE-Specific Optimizations​​

  • 15% reduction in power consumption for PoE ports (IEEE 802.3af/at compliant) during low-traffic periods.
  • Real-time monitoring of connected PoE devices through SNMPv3 and REST API.

​​3. Performance Upgrades​​

  • 20% faster IPsec VPN throughput (up to 300 Mbps) compared to FortiOS 6.0.14, enabled by hardware-accelerated AES-256-CBC.
  • Memory leak fixes in DHCP server processes, resolving instability with >25 PoE-connected endpoints.

​​4. Protocol Support​​

  • Enhanced BGP route reflector capabilities for hybrid SD-WAN deployments.
  • Improved compatibility with Cisco Catalyst 9200 switches for VLAN segmentation.
