Anotace: The article reveals the problem of mitigating an insider threat by creating a time-balanced security system in an organization. Based on Markov chain, the authors propose a basic model of interaction in an “organization – insider” system. The article analytically defines a ratio between the time of an insider attack and the time during which the organization’s security system can neutralize it. The authors propose a concept of a multi-level system of organization protection, which takes into account the involved resources and practical skills of employees, as well as security services. At the end of the article, it is concluded that the proposed concept of the organization’s protection system will be effective against potential insider attacks.
