Welcome to 'Information Security 5 Secure Systems Engineering' course ! • This lecture covers Spectre, another class of attacks exploiting speculative execution, focusing on its ability to leak information across different security domains. It explains the concept of branch prediction, another performance optimization used by processors, and how Spectre leverages it to force the processor to speculatively execute code that should not be accessible. The lecture describes how Spectre manipulates indirect branches, instructions that jump to addresses determined at runtime, to access sensitive data. It highlights the interplay between hardware vulnerabilities (speculative execution) and software vulnerabilities (code patterns that can be exploited) in enabling Spectre attacks. Viewers will gain an appreciation for the complexity and far-reaching consequences of Spectre, emphasizing the need for a holistic approach to security that addresses both hardware and software vulnerabilities. • NPTEL Courses permit certifications that can be used for Course Credits in Indian Universities as per the UGC and AICTE notifications. • To understand various certification options for this course, please visit https://nptel.ac.in/courses/106106199 • #Spectre #SpeculativeExecution #MicroarchitecturalAttacks #BranchPrediction #IndirectBranches #SideChannelAttacks #HardwareVulnerability #SoftwareVulnerability
