Abstract
This paper is based on modern approaches and methods of predicting a certain level of predicting a certain level of security with the help of the need to protect the level of security in the information system,which is considered the most important today. The method of increasing the accuracy and reliability of the assessment of the security level of information systems based on the collected databases and time series model of their weaknesses has been developed. In working on the dissertation, using information protection methodology, system analysis methods, set theory, probability theory, time series theory, developing the concept of building information systems with a predetermined level of security is formed and secured with security mechanisms, web servers, the use of the interaction protocol and the timely understanding of the impact of disruptive ideas and their prevention was formed.
