“…To form a security alliance, trust among the members needs to be organised, maintained and measured. Deljoo et al [4] define trust in the alliance as follows: "a trustor expects a trustee to perform task t and the trustee will not exploit vulnerabilities of the trustor when the trustee is faced with the opportunity to do so." Therefore, every trustee:…”

“…Every collaboration comes with a risk that needs to be minimised. Das et al, [6] defined the relational and performance risks as two distinct risks for the alliance, and Deljoo et al [4] present the risk evaluation framework for the security alliance. Relational risk concerns the behaviour of the alliance members, 1 − Ben(l, r), while the performance risk considers the competence of members to perform the given task, 1−Comp(l, r, t).…”

Collaborative defences against, for example, Distributed Denial of Service attacks require trust between the collaborators. Even in a trusted alliance of collaborators, some members are more trusted than others with the execution of a specific task. This paper shows that trust can be used as a criterion in collaborative defences against attacks on computer infrastructures. We evaluate the implementation of a trust based defence in an overlay network and compare its' performance to other collaborative defences in the same environment. Results show that the trust-based defence has comparable results to the other collaborative defences after the trust values converge to reflect the behaviour of the nodes.

“…• the effective contribution of private persons to formal computer emergency response arrangements, e.g., crowdsourcing, requires recognition and division based on the roles and individual needs and can encourage 'netizens' to co-produce cybersecurity [24]; • trust is key for sharing cyber intelligence and motivating partners to join a cybersecurity alliance [25]; • the timely identification, management and resolution of conflicts among partner organisations is key for successful collaboration [26]; • traditional assessments of security risks often focus on tangible assets, while intangibles such as tacit knowledge are in some cases more important than physical assets [27]; • knowledge sharing is a fundamental factor for strategic decision making, particularly in relation to innovation management and sustainability of collaborative organisations [28]; •…”

Towards the Design of a Collaborative Cybersecurity Networked Organisation: Identification and Prioritisation of Governance Needs and Objectives

The effective response to the proliferation and growing diversity and sophistication of cyber threats requires a broad spectrum of competencies, human, technological and financial resources that are in the powers of very few countries. The European Union is addressing this challenge through an initiative to establish one or more cybersecurity competence networks. A number of existing technologies can support collaboration in networked organisations; however, network governance remains a challenge. The study presented in this article aimed to identify and prioritise network governance issues. Towards that purpose, qualitative and quantitative methods were applied in the analysis of norms and regulations, statutory documents of existing networks, academic sources and interviews with representatives of funding organisations and potential major customers. The comprehensiveness and complementarity of these primary sources allowed to identify 33 categories of governance issues and group them in four tiers, indicative of the respective priority level. The results of the study are currently used to inform and orient the development of alternative models for governance of a cybersecurity network and a set of criteria for their evaluation. They will support informed decision-making on the most appropriate governance model of a future networked organisation, evolving from a project consortium.

In the modern society almost all services are based on data-networks and networked systems. Especially through the growing digitalization an increasing number of services is connected to data-networks. One example of a highly digitalized domain is the healthcare sector, where a cyber-attack could cause extreme circumstances. Decision making requires knowledge about the current situation. Particularly, in the complex domain of cyber security where the boundaries of physical world do not exist, situational awareness has a determinative role. One source for required cyber security information is obtained by sharing information: different organizations share the information between each other. Typically, Cyber security information has classification levels, which affects challenges for information sharing between different organizations. In this study, the model for information sharing between different organizations with different classification levels is developed and tested in the simulation. Because of its importance, the developed model is tested in the simulation of a healthcare domain; however, it can be utilized in all business sectors. In this paper, not only the developed model with simulation results is presented, but also tested in real life scenarios within an existing project.
