Operational Recommendations

  1. ​​Pre-Update Protocol​​:

    • Disable SSL-VPN services using: 
      config vpn ssl settings  
set status disable  
end
    • Validate ASIC status via: 
      diagnose hardware deviceinfo np7lite

  2. ​​Post-Installation Verification​​:

    • Monitor threat detection metrics: 
      diagnose test application ipsmonitor 99  
get system fortiguard status
    • Confirm IoT device classifications: 
      diagnose sys auto-iot list

This release exemplifies Fortinet’s commitment to securing distributed enterprise networks against evolving cloud-based attack vectors. Network architects managing hybrid infrastructures should prioritize deployment within 48 hours to neutralize critical SSL-VPN vulnerabilities while benefiting from industrial IoT protection enhancements.
