Student: Daniil Girskiy

Supervisor: Yulia Grishunina

Faculty: HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE)

Educational Programme: Applied Mathematics (Bachelor)

Final Grade: 8

Year of Graduation: 2018

As a result of the work done, a simulation model was created for the life cycle of two computer systems with the ability to communicate computers on the network, accessing each of the computers to the update database, and unplanned reinstallations of the operating system for successful attacks of the second type of virus. The aim of the work is to find the optimal periodicity of the access of computers to the database of updates, the study of the dependence of profit on the frequency of each computer's access to the database of updates for different intensity of the message using a mathematical model, the construction of a graph showing the results obtained using the Wolfram Mathematica computer algebra system, an imitation model written with the help of an open multi-paradigm compiled programming language Swift to compare the results obtained in the mathematical model. The results obtained in this paper can be used to find the optimal frequency of access of computers to the database of updates.
