Traditional security assessing mostly relies on the personal skills of security experts, often based on best practices and personal experience. The present work is aimed at defining a security metric allowing evaluators to assess the security level of complex cyber-physical systems (CPSs), as critical infrastructures, in a holistic, consistent and repeatable way. To achieve this result, the mathematical framework provided by the open source security testing methodology manual (OSSTMM) is used as the backbone of the new security metric, since it allows to provide security indicators capturing, in a non-biased way, the security level of a system. Several concepts, as component lifecycle, vulnerability criticality and damage potential - effort ratio are embedded in the new security metric framework, developed in the scope of the H2020 project ATENA.","PeriodicalId":210749,"journal":{"name":"Int.

The modelling is merely a part of this undertaking. However, it plays a significant role in the description of the system, how it will behave and what properties it will have. Formal methods, for instance Event-B, are utilised in such cases to assure that the system is correct-by-construction and functions as required. In this work we use a literature review method to collect a body of knowledge that would support the Event-B practitioners with modelling guidelines. We first define the domains in which the guidelines fall and divide them into two categories: beginners and advanced. Then we provide a collection of guidelines as reinforcements for domain-specific applications of Event-B.","PeriodicalId":210749,"journal":{"name":"Int. J. Crit. Comput.

The use of DSU in critical applications raises several issues related to update correctness. Indeed, an erroneous dynamic update may introduce safety vulnerabilities and security breaches. In this perspective, the use of formal methods has gained a large interest since they respond to the high need of rigor required by such applications. Several frameworks were developed to first express update correctness which is based on several criteria. Then, the proposed formalisms are used to specify DSU systems, express correctness criteria and establish them. In this paper, we present a review of researches on the application of formal methods to DSU systems. We give a classification of systems according to the paradigms of programming languages and then we explain the correctness criteria and categorise the articles regarding the approaches of formalisation to establish the correctness. This information is useful to help ongoing researches in having an overview on the application of formal methods in DSU.","PeriodicalId":210749,"journal":{"name":"Int. J. Crit. Comput.

ICSs strictly rely on computer-based systems and on installed remote controllers, which are subject to a constant patch deployment to upgrade functionalities, to resolve security issues and to reduce potential flaws. The patch management is not a trivial process since it can introduce new vulnerabilities within the systems. A key factor to perform successful patch management is to comply with the recommendations provided by the international standards and by the best practices currently adopted in the industry. This paper surveys the few existing international standards on patch management and the best practices, currently adopted in industry, and evaluates the relevance of standards and the best practices to the context of critical infrastructures for particle accelerators.","PeriodicalId":210749,"journal":{"name":"Int.

For development of quality software, it is indeed necessary to specify both functional and non-functional requirements (NFRs). However, unlike functional requirements, NFRs are not given much importance and are often generically captured which results in missing out on quality parameters during CBS development. This lacuna can be taken care with inclusion of details regarding NFRs at initial stages of CBS development. NFRs can be addressed by use of interpretive structural modelling (ISM) and analytical hierarchy process (AHP) methods for identification of critical NFRs. Further, new artifacts have been introduced in use case diagram and reference model to document and validate the identified critical NFRs. Each proposed artefact in software requirement specification (SRS) document was initially analysed individually and then compared with other noticeable methodologies.","PeriodicalId":210749,"journal":{"name":"Int.

The architecture of an encrypted high-performance microprocessor designed on the principle that a nonstandard arithmetic generates encrypted processor states is described here. Data in registers, in memory and on buses exists in encrypted form. Any block encryption is feasible, in principle. The processor is (initially) intended for cloud-based remote computation. An encrypted version of the standard OpenRISC instruction set is understood by the processor. It is proved here, for programs written in a minimal subset of instructions, that the platform is secure against ‘Iago’ attacks by the privileged operator or a subverted operating system, which cannot decrypt the program output, nor change the program’s output to a particular value of their choosing. Performance measures from cycle-accurate behavioural simulation of the platform are given for 64-bit RC2 (symmetric, keyed) and 72-bit Paillier (asymmetric, additively homomorphic, no key in-processor) encryptions. Measurements are centred on a nominal 1 GHz clock with 3 ns cache and 15 ns memory latency, which is conservative with respect to available technology.","PeriodicalId":210749,"journal":{"name":"Int.
