| The risk faced by information security has infiltrated into society economy, military, national security, intellectual property, trade security and personal privacy. Network security is always the key issue of computer network and its application. Traditional theory and technology of network security have three insuperable flaws. Firstly, centralized control method is incompetent to distributed network environment; Secondly, isomorphs of network structure cannot prevent the rapid and extensive spread of suspicious intrusion and virus; Thirdly, because the threat against network security is changing rapidly, the passivity of traditional theory and technology of network security cannot adapt to the changeful network environment. So current network security theory and technology can't solve the network security problem by themselves and the new network security theory is essential.Fault tolerance, as a standard feature of electronic systems intended for long-term missions, is difficult to be implemented by traditional techniques. Inspired by the complex biological system, this paper firstly studies three domains (Embryonics, Immunotronics, Evolvable hardware) of Bio-inspired Fault Tolerance Techniques based on POE model. The hierarchies and fault tolerance strategies of embryonic cells are introduced. The important achievements of Immunotronics, the general architecture of Immuno-Embryonics and antibody learning are stated. The main mechanism of Evolvable hardware is introduced. The future research of Fault Tolerance Computing Techniques is discussed.Then, on the basis of the principle and development of bio-inspired Computer Immune System, this paper presents a computer network immune system model intending to remove the three hidden perils of computer security(Intrusion, Virus, and Abnormity)-LAN Immune System Model based on Host(LISMH),in which the workflow of virus detection and removal in LISMH are emphasized and its strongpoint comparing to other computer immune system... |
