Check your kernel configuration for security issues — based on KSPP, grsecurity, CLIP OS and CIS Benchmark recommendations.

Where to find your kernel config file?
  • /boot/config-$(uname -r) — most common location (Debian, Ubuntu, Fedora)
  • /proc/config.gz — if kernel built with CONFIG_IKCONFIG_PROC=y, extract: zcat /proc/config.gz > my.config
  • /usr/src/linux/.config — if you compiled the kernel from source
  • ls /boot/config-* — lists available configs for installed kernels
