"Wars do not always break out in the conventional war field. They exist currently and ubiquitously in cyber space. Based on the experiences of disease prevention,isolation is always a valid countermeasures. Therefore, the optimal scenario of data exchange between the different risk levels of a cyber system is somehowmaintaining a physical disconnection while data is being transferred.Please be advised that any connection oriented data exchange security system, e.g. fire wall, will be easily penetrated in the coming quantum computing era."
