The human factor is the underlying reason why many cyber attacks are successful, underestimate the severity of potential cyber threats is one of the most common errors. It makes no sense to have sophisticated security systems if the security of the infrastructure can potentially be affected by the work of human beings. The number of device owners is inversely proportional to the cost of ownership. The mean level of awareness and security competence of the user base declines as the user population increases. The average level of ICT risk is a function of the number of devices in use and number of discrete vulnerabilities.”]
