It depends on how many hardening features you want to enable. It's a lot |
| 13 |
easier than it used to be because there's a kernel config thingy that |
| 14 |
lets you pick safe options without understanding all the details. You |
| 15 |
can get a lot of protection for very little risk by enabling pax/grsec |
| 16 |
and checking a few boxes in the hardened kernel config. |
| 17 |
|
| 18 |
Just beware that there are kernel options that will clobber things like |
| 19 |
cpupower and others that will slow down specific programs like clamav |
| 20 |
with JIT. Anyway, we're all here because we like to tinker with things |
| 21 |
until they're broken, right? Give it a try and be sure to read the |
| 22 |
kernel help pages carefully and have fun. You can always switch back to |
| 23 |
a non-hardened kernel and everything will go back to normal. |
