Ensure noexec option set on /dev/shm partition
SedangLevel 1Otomatisros
Deskripsi
The noexec mount option specifies that the filesystem cannot contain executable binaries. The audit requires the noexec 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.
