Interorganizational cooperation in supply chain cybersecurity: a cross-industry study of the effectiveness of the UK implementation of the NIS Directive

The transposition of the EU Directive on Network and Information Security (NIS) by EU Member States involved assigning a set of responsibilities to operators, regulators and policy makers within a national cybersecurity strategy, in order to improve cybersecurity levels across critical infrastructures. This research investigates the perspectives and experiences of organisations affected by the NIS Directive focussing on three different sectors (Energy, Water & Aviation). The authors evaluate the response of different actors to NIS interventions and their challenges in meeting their assigned responsibilities, in particular their ability to oversee supply chain cybersecurity. It proposes further support for partnerships and cooperation across organisations to increase the effectiveness of NIS implementation. Based on results from semi-structured interviews and observations of industry working groups, an approach to supply chain oversight to achieve a balance between control and cooperation is recommended, to improve cybersecurity within industry sectors and across critical national infrastructures. Although our initial focus has been on working mainly with UK stakeholders, we argue that our recommendations have a more general application beyond those countries directly affected by the Directive

A survey on cyber resilience: key strategies, research challenges, and future directions

Cyber resilience has become a major concern for both academia and industry due to the increasing number of data breaches caused by the expanding attack surface of existing IT infrastructure. Cyber resilience refers to an organisation’s ability to prepare for, absorb, recover from, and adapt to adverse effects typically caused by cyber-attacks that affect business operations. In this survey, we aim to identify the significant domains of cyber resilience and measure their effectiveness. We have selected these domains based on a literature review of frameworks, strategies, applications, tools, and technologies. We have outlined the cyber resilience requirements for each domain and explored solutions related to each requirement in detail. We have also compared and analysed different studies in each domain to find other ways of enhancing cyber resilience. Furthermore, we have compared cyber resilience frameworks and strategies based on technical requirements for various applications. We have also elaborated on techniques for improving cyber resilience. In the supplementary section, we have presented applications that have implemented cyber resilience. This survey comprehensively compares various popular cyber resilience tools to help researchers, practitioners, and organisations choose the best practices for enhancing cyber resilience. Finally, we have shared key findings, limitations, problems, and future directions
