Модель системи протидії вторгненням в інформаційних системах

The article proposes a model of intrusion detection systems (IDS), which reflects the main
processes that take place in the system in order to optimize the processes of anti-intrusion. Such
processes in general can be represented as processes of allocation and use of resources that are
allocated for the protection of information. The use of modeling techniques to ensure the
appropriate level of information security has led to the development of many formal security
models that help maintain the appropriate level of security of systems based on objective and
indisputable postulates of mathematical theory. The proposed model of counteracting information
security breaches in IP, in contrast to similar existing models, which are designed to assess the
impact of possible attacks and threats of various levels and make an informed decision on the
implementation of IP intrusion detection systems, provides an opportunity to quickly assess the
current state of IP security. efficiency of formal methods on short limited samples about
parameters of means of protection of IP and parameters of threats influencing elements of IP. The
application of the proposed model will allow to obtain current assessments of the state of
information security, to provide additional time for the preparation and implementation of
measures to respond to threats in order to enhance information security.
