The reports of attack techniques and products for the physical isolation network by Western media marks that the conception of physical space security has evolved from the traditional physical security to offnet attack and defense against which integrated the use of big data, sensor network, etc. This paper describes the extension conception of physical space security, summarizes the current development of physical space information security technology and analyzes the development trend and characteristics. At last proposes the protection and monitoring architecture against offnet attack technology is proposed.
