Introduction to Linux Kernel Hardening with eBPF
The Linux kernel is a critical component of the operating system, responsible for managing hardware resources and providing services to applications. However, its complexity and ubiquity make it a prime target for attackers. Recent CVEs (Common Vulnerabilities and Exposures) and MITRE ATT&CK techniques have highlighted the need for robust security measures to protect the Linux kernel. One effective approach is to leverage eBPF (extended Berkeley Packet Filter)-based security tools for hardening the kernel.
