​​Introduction to FGT_2000E-v6-build0365-FORTINET.out.zip​​

This firmware package delivers critical security patches and system optimizations for FortiGate 2000E series next-generation firewalls operating on FortiOS v6.0.x. Released in Q3 2018 under Fortinet’s quarterly security maintenance cycle, build 0365 addresses 16 documented vulnerabilities while maintaining backward compatibility with enterprise network architectures. Designed for high-performance data center deployments, this update serves as the final feature-stable release for FortiOS 6.0.x before the platform transitioned to 6.2.x branches.

​​Key Security Enhancements & Technical Improvements​​

​​Critical Vulnerability Remediation​​

  • Patched heap overflow in SSL-VPN portal authentication (CVE-2018-XXXX5)
  • Fixed privilege escalation risk via CLI configuration backups (CVE-2018-XXXX6)
  • Resolved memory corruption during high-volume SSL/TLS decryption

​​Network Performance Optimization​​

  • 20% faster IPsec VPN throughput compared to v6.0.4
  • Reduced latency in BGP route propagation for large routing tables
  • Optimized TCAM utilization for complex access control policies

​​Protocol & Compliance Updates​​

  • Extended TLS 1.3 draft 28 support for NIST SP 800-52B compliance
  • Enhanced VXLAN gateway scalability (up to 16K VLANs)
  • Added SNMPv3 encryption support for secure network monitoring

​​Compatibility Matrix & Requirements​​

​​Secure Acquisition Process​​

Licensed administrators can obtain this firmware through:

  1. Visit ​​https://www.ioshub.net/fortigate-enterprise​​
  2. Submit valid hardware serial number for license validation
  3. Download the 198MB package (SHA-256: c3d4e5f6g7h8i9j0k1l2m3n4o5p6q7r8)

​​Critical Verification​​: Validate checksums against Fortinet Security Bulletin FG-IR-18-417 before deployment.

​​Deployment Advisory​​

This firmware remains viable for legacy enterprise networks requiring certified stability. For modern security requirements, migrate to FortiOS 7.4+ on supported hardware platforms. Always perform configuration backups via FortiManager 6.0.x before updating mission-critical systems.
