Abstract. The problem of information security is interpreted as a problem of reservation of threats of information system vulnerabilities by threats of vulnerabilities of the information security system. The approach allows assessing and modeling the threat characteristics and the reliability parameters of protected information system. Requirements to development of a valid threat attacks Markov models with discrete states and continuous time are formulated.
Keywords: information system, information security system, attack, threats of vulnerabilities, threat of attack, reservation of vulnerabilities, modeling, Markov models, characteristics of attack threats
