  The UK energy sector is a prime target for cyber-attacks by foreign states, criminals, ‘hacktivist’ groups and terrorists. As Critical National Infrastructure (CNI), the industry needs to understand the threats it faces to mitigate risks and make efficient use of limited resources. Cyber Threat Intelligence (CTI) sharing is one means of achieving this, by leveraging sector wide knowledge to combat ongoing mutual threats. However, being unable to segregate intelligence or to control what is disseminated to which parties, and by which means, has impeded industry co-operation thus far.
The purpose of this study is to investigate the barriers to sharing and to add to the body of knowledge of CTI in the UK energy sector, while providing some level of assurance that existing tooling is fit for purpose. We achieve these aims by conducting a multivocal literature review and by experimentation using a simulated Malware Information Sharing Platform (MISP) community in a virtual environment.
This work demonstrates that trust can be placed in the open-source MISP plat-form, with the caveat that the sharing models and tooling limitations are under-stood, while also taking care to create appropriate deployment taxonomies and sharing rules. It is hoped that some of the identified barriers are partially alleviated, helping to lay the foundations for a UK Energy sector CTI sharing community.
