Addressing VoIP/WebRTC Security Training Gaps with a Standardized Vulnerable Lab Environment

Introduction: Addressing the VoIP/WebRTC Security Training Void The cybersecurity training ecosystem is replete with tools for web application security, such as DVWA, OWASP Juice Shop, and WebGoat. These platforms have standardized the education of vulnerabilities like SQL injection, cross-site scripting (XSS), and insecure session management by providing controlled environments for hands-on learning. However, the domain of Voice over IP (VoIP) and Web Real-Time Communication (WebRTC) lacks an equivalent framework. Despite their pervasive use in modern communication systems, no standardized, intentionally vulnerable lab environment has existed—until the introduction of DVRTC. DVRTC is not merely another tool; it is a targeted solution to the growing complexity of VoIP and WebRTC protocols, the scarcity of accessible learning resources, and the escalating sophistication of real-world attacks targeting these systems. By providing a hands-on environment, DVRTC enables practitioners to sys
