The paper describes the conceptual model of adaptive control of cyber protection of the informatization object (IO). Petri's Networks were used as a mathematical device to solve the problem of adaptive control of user access rights. The simulation model is proposed and the simulation in PIPE v4.3.0 package is performed. The possibility of automating the procedures for adjusting the user profile to minimize or neutralize cyber threats in the objects of informatization is shown. The model of distribution of user tasks in computer networks of IO is proposed. The model, unlike the existing, is based on the mathematical apparatus of Petri's Networks and contains variables that allow reducing the power of the state space. Access control method (ACM) is added. The addenda touched upon aspects of reconciliation of access rights that are requested by the task and requirements of the security policy and the degree of consistency of tasks and access to the IO nodes. Adjustment of rules and security metrics for new tasks or redistributable tasks is described in the notation of Petri nets.
