本章通过更深入地详细介绍威胁和对策的差异以及针对物理域、网络域和中间区域的具体情况，完善了关键基础设施中安全性的介绍。了解这些差异对于针对当今高级持续威胁 (APT) 的多样性设计有效对策至关重要。由于即使是局部事件也可能产生超出关键基础设施的逻辑或物理边界的深远影响，因此我们用本章的部分内容来讨论和概述模拟方法，这些方法有助于建模和估计跨交织基础设施的安全事件可能产生的影响。这些模拟模型为本书其余部分讨论的博弈论安全模型的后续构建提供了宝贵的信息和数据来源。
This chapter refines the introduction of security in critical infrastructures by going into deeper details about how threats and countermeasures differ and are specific for the physical domain, the cyber domain and intermediate areas. Gaining an understanding of these differences is crucial for the design of effective countermeasures against the diverse nature of today’s advanced persistent threats (APTs). As even local incidents may have far-reaching consequences beyond the logical or physical boundaries of a critical infrastructure, we devote parts of the chapter to a discussion and overview of simulation methods that help to model and estimate possible effects of security incidents across interwoven infrastructures. Such simulation models form an invaluable source of information and data for the subsequent construction of game-theoretic security models discussed in the rest of the book.
