Browser Extension Security and Supply Chain Risk
RCCE students will learn how browser extensions introduce powerful permissions, data access, and third-party trust relationships that can become major security liabilities. RCCE students will learn to assess extension permissions, review update trust, understand enterprise extension governance, identify risky dependencies, and defend against malicious or compromised browser add-ons in user environments. The course covers practical scenarios ranging from extension review to policy enforcement, monitoring, and incident response. 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.
