信息安全风险管理实践：探索DACH地区的现状
Risk Management Practices in Information Security: Exploring the Status Quo in the DACH Region
摘要：
信息安全管理旨在确保信息价值和信息处理系统（即资产）得到适当保护。本集团已采用信息安全风险管理技术，以应对对该等资产的信息安全特性构成风险的威胁及漏洞。本文调查了DACH地区（德国、奥地利、瑞士）信息安全管理中使用的风险管理实践的现状。我们使用了针对战略和运营信息安全和风险经理的匿名在线调查，并从26个组织收集了数据。我们分析了一般实践、文档工件、利益相关者协作模式以及企业用于执行信息安全管理活动的工具类型和数据源。我们的研究结果表明，信息安全风险管理的实践状态需要改进。当前的工业实践严重依赖于人工数据汇集和涉及多个利益相关者的复杂的潜在主观决策过程。专门的风险管理工具和方法被选择性地使用，而忽视了通用的文档工具和利益相关者之间的直接沟通。根据我们的研究结果，我们提出了风险管理实践的发展，更好地符合当前的业务情况，在信息安全管理的指导方针。
英文摘要：
Information security management aims at ensuring proper protection of information values and information processing systems (i.e. assets). Information security risk management techniques are incorporated to deal with threats and vulnerabilities that impose risks to information security properties of these assets. This paper investigates the current state of risk management practices being used in information security management in the DACH region (Germany, Austria, Switzerland). We used an anonymous online survey targeting strategic and operative information security and risk managers and collected data from 26 organizations. We analyzed general practices, documentation artifacts, patterns of stakeholder collaboration as well as tool types and data sources used by enterprises to conduct information security management activities. Our findings show that the state of practice of information security risk management is in need of improvement. Current industrial practice heavily relies on manual data collection and complex potentially subjective decision processes with multiple stakeholders involved. Dedicated risk management tools and methods are used selectively and neglected in favor of general-purpose documentation tools and direct communication between stakeholders. In light of our results we propose guidelines for the development of risk management practices that are better aligned with the current operational situation in information security management.
