Phishing attacks, which pose a serious cyber threat to digital information, monitoring and control systems, are aimed at obtaining personal data by deceiving legitimate participants in the system and gaining unauthorized access. In the research work, the functioning table is a tool for graphical, algorithmic and mathematical modeling, which serves as the main basis for describing, synthesizing and analyzing the dynamic behavior (SADB) of such systems. In this research work, phishing identification mechanisms are integrated into operations and/or processes for managing access to digital information resources to solve the problem. This approach provides valuable insight into the adaptive and dynamic nature of phishing and trust-building cyberattacks. It demonstrates the need to dynamically change the state of the structure to respond to phishing threats by simulating different threat scenarios. Emphasizing the need for real-time strategies and well-designed protocols to combat phishing and other online attacks, a dynamic and adaptive technique based on Petri nets is proposed to ensure the security of structure messages. The study highlights the need for dynamic and adaptive security models to detect and detect emerging threats.
