A kind of university HPC platform security balance method based on the barrel theory

With the rapid development of HPC, more and more attention is paid to the security of HPC. In this paper, a new hierarchical barrel model based on the traditional barrel model is proposed, which is used in two aspects: Firstly, the HPC overall security architecture is a hierarchical barrel, divided by value size and difficulty of offensive and defensive, supplemented with safety measures; Secondly, the security association between layers, different degree of safety protection, follow short board principle. Aiming at the security problem of HPC platform in University design risk indicators, scan two sets of vulnerabilities in different time periods. Use the security balance algorithm to calculate the sample mean and the overall mean, deduce multiple risk points, reference mean to do security optimization. Finally scan the third set vulnerability value and compared with the previous two sets. Experiment results show that the new barrel model has the function of security balance, and can pinpoint the system's short board, effective protection, reduce cost and improve the overall security performance.
