Browser Security Internals and Site Isolation
RCCE students will learn the browser security model including process isolation, rendering boundaries, same-origin enforcement, cross-site isolation, sandboxing, and the trust assumptions that protect modern web sessions. RCCE students will learn to understand how browsers separate content, where those protections fail, how web and browser controls interact, and why client-side risk matters to both defenders and offensive testers. The course covers practical scenarios ranging from browser architecture review to abuse analysis and defensive hardening. RCCE students will learn to analyze complex systems and think like an attacker to better defend the organization. This comprehensive course delivers practical knowledge applicable to real-world cybersecurity operations. Starting from foundational concepts, RCCE students will learn through a combination of concept explanation, practical demonstration, and hands-on exercises.
