- Local end-to-end validation
Supplementary Features:
- Session termination (channel closure and media cessation)
- Multi-user group communications
- Token-based authentication controls
Display Capture
- Implementation of getDisplayMedia()
- Architectural considerations and configuration options
Session Description Protocol (SDP)
- Protocol overview and data components
- Parsing and analysis of SDP content

Requirements
This course is intended for front-end and full-stack developers, technical architects, and engineers responsible for building browser-based real-time communication features, including video conferencing, display capture, and audio streaming. Participants must demonstrate proficiency in JavaScript and core web technologies, with supplemental experience in Node.js and WebSocket-based communication recommended for government-facing projects.

The training helped me expand my knowledge and understanding of Burp Suite. I also realized that what I had learned through self-study was still quite limited. This training was very helpful to me as a QA because Burp Suite is a valuable tool for performing security testing and improving the overall quality of application testing. I will continue exploring this tool and learning more about its features and capabilities.

I really enjoyed learning about AI attacks and the tools out there to begin practicing and actively using for security testing. I took a lot of knowledge away which I didn't have at the beginning and the course met what I hoped it would be. My favorite part shown from the training was Comet Browser and was amazed at what it could do. Definitely something will be looking into more. Overall it was a great course and enjoyed learning all OWASP GenAI Top 10.
