Abstract

The application of Industry 4.0 (I4.0) architectures to the conservative nature of present Industrial Control System (ICS) has brought along many challenges. The ever-changing and dynamically altering threat landscape has led to many hazards and risks w.r.t. safe and secure operation of underlying assets. To understand and manage such risks, organizations perform assessments. Risk assessments performed today are typically handled in a centralized manner on a higher layer of the automation pyramid. The concept of the Asset Administration Shell (AAS) for I4.0 component might provide means to access and process data at the component level throughout the lifecycle, thus taking the assessment from a strictly centralized to a distributed manner. This paper, thus, focuses on the possibility of risk assessment either performed centrally or in a distributed manner aiming at highlighting data sources, acquisition, and processing mechanisms for the same relying on the AAS.

使用资产管理外壳的集中式或分布式风险评估
工业4.0 (I4.0)架构对当前工业控制系统(ICS)的保守性的应用带来了许多挑战。不断变化和动态变化的威胁环境导致了许多危害和风险,而不是基础资产的安全运营。为了理解和管理这些风险,组织需要进行评估。今天执行的风险评估通常是在自动化金字塔的较高层次上以集中的方式处理的。I4.0组件的资产管理外壳(Asset Administration Shell, AAS)概念可能提供了在整个生命周期中访问和处理组件级数据的方法,从而将评估从严格集中的方式转变为分布式的方式。因此,本文着重于集中或以分布式方式进行风险评估的可能性,旨在突出依赖于AAS的数据源、获取和处理机制。
