Ensure nosuid option set on /dev/shm partition

SedangLevel 1Otomatisros

Deskripsi

The nosuid mount option specifies that the filesystem cannot contain setuid files. The audit requires the nosuid mount option on /dev/shm when it is a separate mount (findmnt); not applicable otherwise. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
