Sorry to bump this, but I see there's a good bit of activity recently
and this is a really simple, but aggravating, issue that I cannot seem
to resolve.
My disk checks keep giving me back critical errors, specifically the two
below:
DISK CRITICAL - /sys/kernel/security is not accessible: Permission
denied
DISK CRITICAL - /sys/kernel/config is not accessible:
Permission denied
I'm not sure why this is, since both directories (filesystems?) are 644
in permissions and I'm obviously not running any sort of mandatory
access control (i.e. SELinux or AppArmor). Even umounting these
filesystems makes no difference.
You probably want 755 on the directory entries so that traversal is
permitted (that's the "x" bit". 644 allows reading for everybody but
not the ability to descend to deeper levels. 751 can be useful if one
wants to allow the world to traverse, but not, read a directory (files
can still be accessed if one knows the name, but one cannot find the
name of a file).
Cheers!
