Getting the error in ConfigServer Firewall?

/dev/shm is not mounted with the noexec,nosuid options (currently: none). You should modify the mountpoint in /etc/fstab for /dev/shm with those options and remount.

Simply follow the following:

Use the command: nano /etc/fstab

Replace this line: tmpfs /dev/shm tmpfs defaults 0 0

With this one: tmpfs /dev/shm tmpfs defaults,noexec,nosuid 0 0

Then Remount: mount -o remount /dev/shm
