Two-Level System of on-Line Risk Assessment in the National Cyberspace
The paper presents a hierarchical, two-level approach to on-line cyber risk assessment at the national level. It takes into account cyber threats and vulnerabilities identified at the lower level formed by essential service operators and digital service providers. A computational algorithm is propos...
