Verify Permissions On /etc/sysctl.d Directory
An XCCDF Rule
Description
To properly set the permissions of /etc/sysctl.d, run the command:
$ sudo chmod 0755 /etc/sysctl.d
Rationale
Setting correct permissions on the /etc/sysctl.d directory is important because this directory hosts kernel configuration. Protection of this directory is critical for system security. Restricting the permissions ensures exclusive control of the kernel configuration.
