+There are plenty of security hardening options for the Linux kernel. A lot of them are
not enabled by the major distros. We have to enable these options ourselves to
make our systems more secure.
But nobody likes checking configs manually. So let the computers do their job!
-__kconfig-hardened-check.py__ helps me to check the Linux kernel Kconfig option list
+__kconfig-hardened-check.py__ helps me to check the Linux kernel options
against my security hardening preferences, which are based on the
- [KSPP recommended settings][1],
- [CLIP OS kernel configuration][2],
- Last public [grsecurity][3] patch (options which they disable),
- [SECURITY_LOCKDOWN_LSM][5] patchset,
- - Direct feedback from Linux kernel maintainers (see [#38][6], [#53][15], [#54][16]).
+ - Direct feedback from Linux kernel maintainers (see [#38][6], [#53][15], [#54][16], [#62][17]).
+
+This tool supports checking __Kconfig__ options and __kernel cmdline__ parameters.
I also created [__Linux Kernel Defence Map__][4] that is a graphical representation of the
relationships between security hardening features and the corresponding vulnerability classes
