ISA Taiwan Section Webinar Series | Tim Hsiao (蕭冠文), xSeriCon
本次 Webinar，xSeriCon 團隊將主題聚焦於「功能安全（Functional Safety）與工控資安（Cybersecurity）的跨領域協同合作」。以真實發生的工廠資安事件（如 TRISIS 事件）為導讀：剖析當資安防線失守時，對工廠實體安全與營運帶來的致命衝擊。
Topic：
網路時代的功能安全防線：工控資安如何補強傳統 SIF 生命週期的致命盲點？
Shielding Functional Safety in the Cyber Era: How OT Cybersecurity Reinforces the Fatal Blind Spots of the Traditional SIF Lifecycle
Abstract：
功能安全系列標準 (Functional Safety, IEC61508/IEC61511/ISA84) 主要探討工廠設備發生「硬體隨機失效(random hardware failure)」或「無惡意的人為系統疏失(system failure)」時，所造成不可逆的嚴重後果，並如何藉由獨立保護層、E/E/EP與SIS來降低不可接受的風險。然而，2017 年發生的 TRISIS（Triton）事件震驚全球，駭客利用惡意程式直接入侵並篡改安全 PLC。這敲響了工業界的警鐘：當 SIS 遭遇蓄意的網路攻擊時，傳統的隨機失效機率計算將失去意義，甚至導致功能安全防線完全失效。
Functional safety standards (IEC 61508 / IEC 61511 / ISA-84) focus primarily on reducing irreversible, catastrophic consequences caused by “random hardware failures” or “inadvertent human systematic failures” through Independent Protection Layers (IPL), E/E/PE systems, and Safety Instrumented Systems (SIS). However, the infamous TRISIS (Triton) incident in 2017 shocked the global industrial community when hackers utilized malware to directly infiltrate and tamper with a safety PLC. This sounded a major alarm for the industry: when a SIS faces a deliberate cyber-attack, traditional random failure probability calculations no longer hold, potentially leading to the complete failure of functional safety defenses.
本講座以功能安全為核心，介紹功能安全的三大生命週期階段與功能安全管理，並延伸資安議題如何作為傳統安全生命週期的輔助力量：
With functional safety at its core, this webinar introduces the three main phases of the safety lifecycle along with Functional Safety Management (FSM). It will further explore how cybersecurity issues serve as an auxiliary force to support the traditional safety lifecycle across these key stages:
- 風險分析階段(Risk Analysis)：當資安問題成為製程異常的起始事件？！
Risk Analysis Phase: When a cyber vulnerability becomes the “Initiating Cause” of a process upset?! - 設計實現階段(SIS design)：功能安全中，安全需求規格對於資安的要求
SIS Design Phase: The cybersecurity requirements within the Safety Requirements Specification (SRS) in functional safety. - 操作維護階段(Operation & Maintenance)：變更管理(MOC)與補丁(patching)的衝突
Operation & Maintenance Phase: The conflict and harmonization between Functional Safety Management of Change (MOC) and rapid cybersecurity patch management.
本場 Webinar 旨在協助功能安全工程師與資安專業人員建立共識，理解資安如何成為功能安全的保護傘，共同守護工業現場的生命安全。
This webinar aims to help functional safety practitioners and OT security professionals reach consensus by demonstrating how cybersecurity serves as an indispensable shield for safeguarding lives and operations on the industrial plant floor.
