This paper studies the problems of “security meridian-collateral” and “security confrontation” systematically and refreshes the traditional concept of security. On the one hand, based on the model of “meridians” in Chinese traditional medicine for the first time, this paper proves the following results strictly by the probability method. There is a complete “meridian-collateral diagram” in Internet of things and any finite system, so that any “sickness” of the system can be cured effectively. On the other hand, this paper studies the network attack and defense from the perspective of the information theory. Through mathematical modeling, based on the famous Shannon's coding theorem, the research on the ability problem of attacker and defender is transformed into the research on the channels of attacker and defender. From the perspective of the channel capacity in information theory for the first time, this paper gives the reachable theoretical limitation of the attack ability of hacker and the defend ability of honker precisely.
