Improving the method of monitoring the state of the website by detecting user interface vulnerabilities and browser errors

Abstract

The paper presents an improved method of monitoring the state of a website with a focus on the security of the client interface (front-end). An architectural solution is proposed based on the use of Selenium WebDriver in combination with Chrome DevTools Protocol (CDP) to emulate user interaction with the web interface, intercept internal browser events, and then transfer the collected data to the Zabbix monitoring system for further analysis and alerts. The methodology allows detecting security breach indicators, such as JavaScript errors, XSS injections, violations of CSP/CORS policies, cases of mixed content, vulnerabilities related to dangerous cookie flags, and other typical signs of compromise or incorrect user interface implementation.
