Listen to Your Engine - Unearthing Security Signals from the Modern Linux Kernel

Dive into a comprehensive exploration of kernel event analysis and security signal detection in modern Linux systems. Learn how to unearth valuable security insights from the complex machinery of system calls, focusing on indicators of privilege escalation, resource abuse, and side-channel attacks. Explore both traditional and cutting-edge tools for kernel observation, including ptrace, kprobes, tracepoints, and eBPF. Examine real-world attack scenarios such as Shellshock, Apache Struts, and Meltdown, identifying key system call events that serve as exploit indicators. Gain insights into generalizing high-grade signals for future attack detection and understand the challenges in improving system call analysis. Benefit from practical recommendations for implementing system call logging and analysis in your own environments, based on experiences from deployments in global financial institutions.
