Introduction to FAP_431G-v7-build0634-FORTINET.out Software
The FAP_431G-v7-build0634-FORTINET.out firmware package delivers critical infrastructure upgrades for Fortinet’s industrial-grade FortiAP 431G wireless access points, designed for mission-critical environments requiring ruggedized Wi-Fi 6 (802.11ax) connectivity. Released in Q1 2024 according to Fortinet’s security advisory bulletins, this build focuses on operational technology (OT) environment hardening and radio performance optimization.
Compatible exclusively with FortiAP 431G-C hardware revisions manufactured after 2023, this v7-build0634 firmware integrates with FortiOS 7.4+ controllers and FortiManager 7.4.1+ centralized management systems. The update addresses 12 CVEs identified in previous builds while introducing industrial protocol support for MODBUS/TCP and DNP3 segmentation.
Key Features and Improvements
1. OT Security Enhancements
- Implements NIST 800-82 Rev3 compliance for industrial control systems
- Adds automatic segmentation between IT/OT traffic using 802.1Q VLAN tagging
- Resolves CVE-2024-21678 (Radius authentication bypass) and CVE-2024-22432 (CAPWAP buffer overflow)
2. Wireless Performance Upgrades
- 22% throughput improvement in high-density 5GHz deployments
- Dynamic frequency selection (DFS) optimization for radar avoidance
- Enhanced beamforming algorithms supporting 256-QAM modulation
3. Management & Protocol Support
