Research on computer network security based on pattern recognition

The major reason for unsatisfied security is that the current network techniques are mainly based on the trade-off among security, convenience and performance. Namely it is impossible to reach the perfection. The latest advances on modern biology immune evolution theory reveal that the key of consummate nature immune mechanism is pathogens recognition based pattern. The basic benefit of pattern recognition to immune system is: what is called ´pattern´ is just ´sort´, The comparison and recognition based on a sort is certainly more efficient and less wasting than that based on the members of a sort. As all known, the computer network security system is very similar in functionality to the nature immune system. This article tries to apply the pattern recognition mechanism to the computer network security. the applications of multivariate statistical analysis and genetic algorithm in the implement algorithm of security system are mainly discussed in the article.
