The invention discloses an information system risk analysis and security situation evaluation method. The method comprises the following steps: step 1, establishing a risk analysis and security situation evaluation index system; 2, calculating various evaluation indexes of risk analysis and security situation awareness, and determining the weight of each specific index by using an analytic hierarchy process; and step 3, calculating a utility value corresponding to each evaluation index according to the utility function, and further calculating a total evaluation value of information system risk analysis and security situation to complete evaluation. Research of an information system risk analysis and security situation assessment method is an important direction for people to pay attention to information security in recent years. According to the invention, risk analysis and situation assessment of an information system are refined through equipment state assessment, attack behavior assessment, abnormal behavior assessment and system vulnerability assessment by means of an analytic hierarchy process.
Description
technical field [0001] The invention relates to the fields of information security technology and big data technology, in particular to a method for risk analysis and security situation assessment of an information system. Background technique [0002] With the increasing development and popularization of Internet technology and mobile communication technology, big data platforms are also facing network threats and data security issues. The amount of information exchange between big data platforms and users has been greatly increased, and data security and risk prevention in the field of big data platforms are more complicated than traditional networks. For example, the most common enterprise information system is the fundamental guarantee and important means of enterprise production and management, and the security of the information system is fundamental to the stable and reliable operation of the information system. [0003] The research on information system risk analys...
