Verify User Who Owns /etc/sysctl.d Directory

An XCCDF Rule

Description

To properly set the owner of /etc/sysctl.d, run the command: 

$ sudo chown root /etc/sysctl.d

Rationale

The ownership of the /etc/sysctl.d directory by the root user is important because this directory hosts kernel configuration. Protection of this directory is critical for system security. Assigning the ownership to root ensures exclusive control of the kernel configuration.
