Building the Truman Show: A TrustZone-Based Framework for Lightweight Out-Of-Band Kernel Security Monitoring

The increasing number of vulnerabilities in operating systems, together with sophisticated kernel-level threats e.g., rootkits, has weakened the effectiveness of traditional in-kernel protection mechanisms. Since these defenses operate at the same privilege level as the kernel, they share the sam...
