“…These include Generic and Specific Sensor, Generic and Specific Indicator, State Histogram Sensor, and Histogram Analysis Indicator. Halang et al produced several papers on UML profiles and models for fault-tolerant systems [51,52] that included a safety shell pattern based on a Reconfiguration Management pattern.…”

Patterns embody the experience and knowledge of designers and are effective ways to improve nonfunctional aspects of software systems. Although there are several catalogs and surveys of security patterns, there is no catalog or general survey about dependability patterns. Our survey presented an enumeration of dependability patterns, which include fault tolerance, reliability, safety, and availability patterns. After defining classification groups and showing basic pattern relationships, we showed the references to the publications where these patterns were introduced and enumerated their intents. Another objective was evaluating these patterns to see if their descriptions are appropriate for a possible catalog, which would make them useful to developers and researchers. We found that most of them need remodeling because they use ad hoc templates or no templates. We considered some models from which we can derive patterns and methodologies that incorporate the use of patterns to build dependable software systems. We also provided directions for research.

This study presents an enumeration and evaluation of reliability patterns. We first catalog these patterns to make them accessible and useful to software developers and system designers. The objective here is to identify areas for which there are no patterns or the existing patterns are not complete enough to be useful to software designers. The patterns are classified based on the reliability properties they provide. As examples of our methodology we evaluate some of the patterns discussed in this survey.

“…There are multiple, well established methodologies and techniques to address safety concerns during the development process (Leveson, 1995), however, for the model presented in Figure 2, we opted to choose an approach named safety shell, because it fits well into a concept of analogy between safety and security ( Figure 3, Gumzej and Halang, 2009).…”

“…By "testing first" the hardware processor or software shell will either validate or invalidate the current action and/or the desired action. It has been developed further by Gumzej and Halang (2009) to map the design on the UML model. In essence, as shown in Figure 3, the physical environment is separated from the controller by an array of guards forming the shell.…”

Security is a system and software property essential in protecting infrastructure critical to the nation's business and everyday operation. It is often related to and overlapping with other trustworthiness properties, such as safety and/or reliability. Mutual relationships of these properties and their interactions in real world systems have been studied by multiple authors in a recent decade; however, they are rarely viewed jointly in the context of critical infrastructure. The objective of this paper is to take a closer look at the relationship of security with safety in computing systems, and present a unified view for further research. In particular, the paper presents an overview of the state-of-the-art and focuses on the discussion of the unifying architecture, which leads to interesting observations how security and safety are related. Preliminary experiments on using safety concepts to assess security in industrial control systems with monitoring tools are discussed.
