新的系统和功能不断部署在复杂的领域,如空中交通管理(ATM)。不幸的是,在处理变更和评估变更对关键特性(如安全性、安全性等)的影响方面,方法学提供的支持有限。本文关注的是变更需求如何影响安全属性。变更需求是要在系统中实现的变更的规范。本文报告了我们的经验,以支持一个进化的风险分析,以便评估变更需求及其对安全属性的影响。特别是,本文通过在ATM案例研究中使用CORAS模型驱动的风险分析的风险评估练习,讨论了领域专家如何感知结构化风险分析模型的变化。它讨论了支持风险分析的结构化模型如何帮助领域专家分析和评估变化对关键系统特性的影响。
New systems and functionalities are continuously deployed in complex domains such as Air Traffic Management (ATM). Unfortunately, methodologies provide limited support in order to deal with changes and to assess their impacts on critical features (e.g. safety, security, etc.). This paper is concerned with how change requirements affect security properties. A change requirement is a specification of changes that are to be implemented in a system. The paper reports our experience to support an evolutionary risk analysis in order to assess change requirements and their impacts on security properties. In particular, this paper discusses how changes to structured risk analysis models are perceived by domain experts by presenting insights from a risk assessment exercise that uses the CORAS model-driven risk analysis in an ATM case study. It discusses how structured models supporting risk analysis help domain experts to analyse and assess the impact of changes on critical system features.
