On the basis of asset

threat

vulnerability and risk assessment of basic elements

based on the threat of trapezoidal fuzzy analytic hierarchy process in e-government information security risk assessment method.The method for threat as the core

through the analysis of threats

trapezoidal fuzzy number

analytic hierarchy process

combined with the multiple attribute decision making theory to get the probability of occurrence of the consequences of threat

attribute and attribute value

get of e-government information systems security threat index

finally uses the threat index on the risk sort

get system information security risk rating.The simulation results show that

the method is able to quantify the e-government system information security risk index

to effectively improve the accuracy of risk assessment

is an effective evaluation method of information security in electronic government system.
