Research on Multidimensional Information Security Assessment Based on Big Data

In order to ensure the security of multi-dimensional information, this paper proposes a research on key technologies of multi-dimensional information security risk assessment based on big data framework. According to the characteristics of multi-dimensional information security data, security division is carried out, intrusion data impact parameters are collected, and intrusion risk budget is carried out according to different impact parameter values and divided security levels, so as to realize accurate evaluation of multi-dimensional information security risks. Finally, the experiment proves that the key technology of multidimensional information security risk assessment based on big data framework has higher practicability and accuracy, and meets the research requirements.
