Information Security Solution Decision-Making Based on Entropy Weight and Gray Situation Decision

To determine the choice of information security solutions, the method based on entropy weight was given to compute the weights of indexes of the solutions. And then, the weights were used to evaluate the solutions by multi-attributes decision and ideal indexes method. The gray situation decision-making was introduced for solutions decision, and entropy weights were also used with gray solution decision to choose the solutions. The characteristics of diverse methods mentioned were analyzed.
