The protection of personal infocommunication systems (for example, computers) against malicious programs and spam is the prerogative of the owners of these systems. The damage from the loss of information stored in a personal system, as a rule, is rather insignificant and affects only the owner of this system. Privacy and a low level of regulation are typical of personal information systems.
The employees of governmental or non-governmental organizations doing official work at home on a personal system can unintentionally make the system a launching point for the implementation of attacks aimed at official infocommunication system, or facilitate the leakage of official information, or unintentionally bring a malicious program from the home computer to a work place. In this case, mass distribution of malicious programs and outbreaks of virus “epidemics” are possible.
