Abstract:
Cyber incidents and business interruptions rank as the foremost business risks. With Early Warning Systems (EWS), that work in parallel with other cyber mechanisms, organisations can independently manage cyber-sensitive intelligence-related data. This article provides a qualitative multi-case study analysis. The data consists of systematic reviews and cross-case conclusions of six (n = 6) case studies on information sharing. EWS is a valuable tool that can help critical infrastructure providers protect against cyberattacks. EWS can provide a platform for sharing information and resources. This can help improve situational awareness, enhance incident response, and facilitate collaboration. between critical infrastructure providers, as critical infrastructure operators and relevant Law Enforcement Agencies (LEA) can share information on cyber incidents and monitor cyber incident progress. EWS can be used to exchange cyber threat intelligence and information sharing can be facilitated w
ith a common reference library where alerts can be shared as tickets. This would enable information exchange in both directions.
