# Forti OT Security (NSE7)整理筆記

## IT與OT的不同

我們將計算機和資料網路稱為資訊科技（IT; information technology）；
工業控制系統（ICS; industrial control system）的操作和程序控制，則通常被稱為運營科技（OT）。

OT是在隔離和獨立的網路中執行，目標與要求和IT完全不同，但這些己開始發生變化。

在最基本的層面上，IT負責資料的建立、傳送、儲存和保護。網路遭入侵可能會對組織產生直接的財務衝擊，通常會讓客戶喪失信心，遭受罰款和處罰，甚至是訴訟。

OT則專注於建立和維護具有實體影響的控制過程，例如製造廠房和生產環境現場。然而，最近的發展，包括需要更有效地在數位化市場中競爭，現在這些傳統上彼此獨立的運作環境正在融合。越來越多的產業已開始藉由部署新的工業物聯網（IIoT）設備（例如智慧電錶、自動化資產分配系統，以及自我監控變壓器），將網路和數位通訊整合到OT之中。

如何著手進行

這些差異並不棘手。透過精心的規劃和協調，結合開放式的溝通和有效傾聽，對於融合這些不同環境來獲得潛在利益至關重要。這些包括：

策略執行的調整：團隊領導者必須明白且認同融合這些資源的企業目標和益處。擁有共同的目標和明確認同的結果，有助於所有團隊推動有效的解決方案。

建立聯合工作小組：一旦確定了目標和結果，很少有方法會比將所有受影響的團隊代表聚集在一起，共同發表意見，思辯策略，制定項目範圍，以及訂定一套共同的流程更有效。第一個目標應該是相互教育這個項目會帶來的挑戰。這將有助於推動各方都能接受的解決方案。當然，要為這個過程做好準備需要一些時間。

執行先導計劃：這通常是不言而喻的，但聯合工作小組概述的流程每一步都需要在受控環境中執行，有時是重複執行，然後才能在生產網路中啟用。這之中有很多利害關係必須考量，因此在將操作控制、安全措施和應急計劃應用到現場環境之前，不斷地進行微調是非常重要的。

融合不僅僅涉及技術

整合IT和OT需要的不僅僅是融合網路資源。企業組織必須避免掉入陷阱，為其網路的OT部分成立另一組並行的安全團隊。工作人員、培訓和資源的重複，不僅浪費企業組織的預算，而且由此產生的組織差異，也可能帶來治理、風險管理和合規等問題。

解決複雜性的最佳方法是簡化它

在數位經濟時代要獲得成功，必須開發能夠完善利用所有可用資源的整合網路，甚至是OT網路內部的ICS / SCADA系統。雖然惡意的網路駭客不斷展現他們的攻擊能力，但組織需要的並非在機櫃中添加新的隔離設備，而是藉由部署整合的安全架構優先考量關鍵功能，例如速度、協作、進階分析，以及基於風險的決策擬訂。這樣的方法圍繞靈活的織網策略構建，能以機器的速度和規模實現全方位的保護，同時將IT和OT環境中適當的解決方案，整合成一個集中式的自動化的安全系統。

## PERA
PERA為企業總體規劃和實現提供了一種結構化的方法，並建模。

任何企業只有三個主要組成部分:
- 物理工廠/生產設施
- 人,組織
- 控制和信息系統
PERA提供了一個企業生命周期模型，它清楚地定義了物理工廠、人員和信息系統之間的角色和關係。

每個企業可以被劃分為明確定義的「階段」

![](https://i.imgur.com/0t1Hy3P.png)

以下是分階段的項目管理的重要規則：

- 在每個階段結束時定義清晰的「可交付內容」
- 不要在所有感興趣的團體正式簽署前進入下一階段。
- 除非設計不安全或無法工作，否則不要回溯先前階段所定義的信息。


項目管理有兩個基本規則:
- 分而治之
- 不要把它切得太厚

據說吃大象的唯一辦法就是得到很多幫助。類似地，大型項目必須被劃分為更小的部分，可以由不同的團隊並行完成(分而治之)。

不幸的是，不同團隊之間必須共享的信息越多，協調和管理就越困難。因此，將項目劃分為子項目是至關重要的，以最小化跨子項目邊界的信息流(不要在最密集的地方劃分)。企業系統必須有效地與物理工廠工程和人力和組織發展相結合。

PERA提供了一個生命周期模型，演示了如何將企業系統、物理工廠工程和組織開發從企業概念集成到解散。

PERA方法是「GERAM」即 「General Enterprise Reference Architecture Methodology」通用企業參考體系結構方法的最佳選擇。PERA已被用作ISA 95和其他一些企業集成標準的基礎。
