在过去的50年里，信息和通信技术（ICT）为有组织社会的几乎所有部门做出了贡献。因此，信息安全对于依赖信通技术的若干社会和商业流程至关重要。信息安全的一个维度涉及信息和计算资源的可用性。对系统的正确操作和最终用户的接受来说，以适当的反应时间对授权请求作出反应至关重要。但是，尽管其他安全参数已经得到了很好的研究和分析，但可用性却没有。在本文件中，一直从质量角度研究信通技术安全的这一基本参数。我们的目标是为信息可用性的形式基础提供基础。像这样的方法对于问题域的概念描述可能很有用，同时这种概念化也可能有助于实现对于安全信息系统开发至关重要的指导方针。
During the last fifty years Information and Communication Technology (ICT) has contributed to almost all sectors of organized societies. As a result, information security is fundamental for several social and business processes that rely on ICT. One dimension of information security concerns availability of information and computational resources. It is essential for a system’s correct operation and its acceptance from end-users to respond with proper reaction times to authorized requests. But whereas other security parameters have been studied and analysed very well, availability has not. Throughout this paper this fundamental parameter of ICT security is under study through a qualitative perspective. We aim at providing the basis for a consequent formalistic foundation of information availability. Approaches like these may be useful for the conceptual description of the problem domain, whilst this conceptualisation may also help in the realization of the guidelines, which are essential for the development of secure information systems.
