Introduction to FGT_100D-v6-build1066-FORTINET.out Software
The FGT_100D-v6-build1066-FORTINET.out firmware delivers critical security patches and operational optimizations for FortiGate 100D series next-generation firewalls under FortiOS 6.4.15. Released in Q4 2024, this build addresses 6 CVEs while enhancing threat detection efficiency for small-to-medium business networks.
Exclusively compatible with FortiGate 100D appliances, this update improves hardware-accelerated security services for distributed offices requiring Unified Threat Management (UTM) capabilities. The 100D series supports up to 5 Gbps threat-protected throughput, making it ideal for retail branches and remote work environments with limited IT infrastructure.
Key Features and Improvements
Security Enhancements
- CVE-2024-41999 Mitigation: Patches a heap overflow vulnerability in SSL-VPN portals that could enable remote code execution.
- FortiGuard IPS Expansion: Adds 28 new intrusion prevention signatures targeting cryptojacking scripts and IoT botnet command-and-control servers.
Performance Optimization
- NP6Lite Security Processing: Achieves 3.8 Gbps IPSec VPN throughput (15% improvement over FortiOS 6.4.12) with full deep packet inspection.
- Memory Allocation: Reduces RAM consumption by 18% during concurrent SSL inspection of 2,000+ sessions.
