Abstract:

As a part of Web security, business security has been paid more and more attention. It is very difficult to protect and forewarn when the hacker using business logic vulnerabilities. Based on the subtle difference of business process caused by the exploitation of business logic vulnerabilities, this paper uses Markov chain to form the characteristic model of normal operation sequence and abnormal operation sequence through the training of operation log data, so as to realize the effective early warning of the exploitation of business logic vulnerabilities, and explore the practical application mode and value.

Key words: business security, Markov chain, business process, early warning
