Design and Implementation of Distributed Web Application Vulnerability Assessment Tools for Securing Complex Microservices Environment

Modern web applications with complex distributed architectures present significant challenges in vulnerability assessment that traditional approaches fail to address effectively.This research introduces the Distributed Vulnerability Management System (DVMS), implementing a multi-agent architecture to enhance vulnerability detection while eliminating single points of failure.The methodology employs the Nuclei vulnerability scanner across five Open Web Application Security Project (OWASP) security domains, expanding beyond conventional vulnerabilities to include Security Misconfiguration, Vulnerable Components, and Sensitive Data Exposure.Experimental results demonstrate detection accuracies of 80% for Injection, 85.71% for XSS, 80% for Security Misconfiguration, 50% for Vulnerable Components, and 90.91% for Sensitive Data Exposure.The distributed architecture enables parallel processing and optimizes security resource allocation across network infrastructures.While showing promising results in comprehensive security coverage, the system identifies areas for future enhancement in detection accuracy and vulnerability scope expansion.This research contributes a scalable, distributed approach to vulnerability management particularly suited for modern web applications, providing organizations with enhanced security assessment capabilities in complex technological environments.
