Abstract:

A security capacity assessment method based on security behavior ontology,was proposed to collect users' be-havior data from their smartphones under unconscious condition to solve the problem of detecting mobile phone users' real existing insecure behaviors.A security behavior ontology was set up for formalizing the phone,message,network and App behavior data of mobile phone users and relevant rules were also set down for determining and associating inse-cure actions.Referring to the notion of attack graph,an insecure behavior detection algorithm was proposed based on behavior association graph for analyzing the paths of insecure behaviors dynamically.Furthermore,a competency model of information security capability assessment was presented for realizing the quantitative evaluation of information secu-rity capability of users.The experiment results prove the effectiveness of present competency model for insecure behavior path detection and security ability assessment.

Key words: security behavior ontology, behavior analysis, capability assessment, mobile security
