Investigation of PCFA in Assessing Main Function Indexes of Intrusion Detection System in Network Security

According to mathematical analysis, using primary components and factor analysis (PCFA) and its advantages, the main function indexes of intrusion detection system in network security are analyzed and assessed. Based on PCFA model and the scores by the experts, the authors computed some results that can reflect some aspects about main function indexes of intrusion detection system in network security. Through case study, it can be seen that some indexes play very important role in analyzing and assessing main function indexes of intrusion detection system in network security and all the reasons should be considered because network security depends on the interaction of all the reasons. Through analysis and deduction, it is concluded that, under the premise of minimizing the information loss of data, the application of PCFA in assessing intrusion detection system in network security approved to be practicable.
