Description:
Explore a comprehensive analysis of control-flow integrity (CFI) and its implementation challenges in this 24-minute conference talk. Delve into the concept of unique code target property and its potential to enhance CFI effectiveness. Examine the limitations of existing CFI approaches and understand why they fall short in preventing control-hijacking attacks. Learn about the innovative UCFI (Unique Code Target Property for Control-Flow Integrity) method, its implementation, security benefits, and efficiency considerations. Investigate the use of Intel PT for efficient analysis and path reconstruction. Discuss backward-edge CFI and compare UCFI with other techniques like CPI. Gain valuable insights into advancing cybersecurity measures against sophisticated control-flow attacks.
