1. Introduction to FGT_600E-v6-build1579-FORTINET.out Software

This firmware package delivers critical security enhancements for FortiGate 600E series next-generation firewalls under FortiOS 6.4.9 branch. Released in Q4 2024, the build1579 revision specifically targets memory management vulnerabilities in medium-to-large enterprise networks while maintaining backward compatibility with Security Fabric deployments.

Designed for environments requiring 20Gbps+ threat inspection throughput, the update supports FortiGate 600E hardware appliances (FG-600E, FG-601E) with NP6 security processors. The maintenance release resolves 14 documented stability issues from previous 6.4.x versions, particularly those affecting SSL-VPN session handling during peak traffic loads exceeding 400,000 concurrent connections.

2. Key Features and Improvements

​​Security Enforcement​​

  • Patches CVE-2024-55592 (CVSS 8.9): Eliminates buffer overflow risk in IPS engine during fragmented IPv6 packet processing
  • FortiGuard threat intelligence updates detect 5 new cryptomining malware variants including CloudHacking.ASM

​​Performance Upgrades​​

  • 15% improvement in HTTP/3 inspection throughput through optimized QUIC protocol handling
  • ASIC-accelerated flow analysis sustains 1.8Tbps threat prevention at 55% CPU utilization

​​Management Enhancements​​

  • REST API response times reduced by 25% for bulk policy modifications
  • FortiCloud synchronization now supports multi-admin configuration auditing

​​Protocol Support​​

  • TLS 1.3 compliance updates for PCI-DSS 4.0 requirements
  • Enhanced multicast routing support for SD-WAN deployments (PIM-SM/SSM)

3. Compatibility and Requirements

​​Component​​ ​​Specification​​
Supported Hardware FortiGate 600E (FG-600E/FG-601E)
Minimum FortiOS 6.4.5 (build1828)
Storage Requirement 2.5GB free disk space
Memory Threshold 16GB RAM minimum
