National Cyber Security Sensor Networks and the Human in the Loop

Abstract:

Organisations recently started to exchange security relevant information on cyber incidents to timely mitigate the effects of newly discovered malware and other forms of cyberattacks. Moreover, state actors take over their role as information brokers through national cyber security centres and distribute warnings on new attack vectors and vital recommendations on how to mitigate them. Although many of these initiatives are effective to some degree, they also suffer from considerable limitations. When going beyond pure technical indicators, extensive human involvement is required to manually review, vet, enrich, analyse, and distribute security information until relevant information reaches a decision maker. Recent research therefore proposes the automatic collection, analysis, and preparation of security data to effectively overcome limiting scalability factors. While this seems to work at an organisational level, the elevation of these approaches to a cross-organisational and even national level is not straightforward. This paper investigates where and why the human factor seems irreplaceable and sheds light on the limitations of autonomous cyber security sensor networks at the national level.
