Linux Kernel Hardening Best Practices

Kernel Hardening

A comprehensive guide to hardening the Linux kernel with KASLR, CFI, seccomp, module signing, and memory protections for enterprise deployments.

Key Techniques

1. KASLR: Kernel Address Space Layout Randomization

2. CFI: Control Flow Integrity

3. seccomp: Secure computing mode for syscall filtering

4. Module signing: Only allow signed kernel modules

5. Memory protections: Stack canaries, heap randomization
