Secure /tmp and /dev/shm partition

Posted on 02 November 2010 by Ndungu

This is you secure your VPS partitions in ssh

Is it a Dedicated server OR a VPS? If it’s a Dedicated server, edit the /etc/fstab file

vi /etc/fstab

replace “defaults” in front of /tmp, /dev/shm to

nosuid,noexec,rw

Save the file and remount the partitions:

mount -o remount /tmp
mount -o remount /dev/shm

To secure /var/tmp, rename the existing /var/tmp and create a symlink

mv /var/tmp /var/tmp_bak
ln -s /tmp /var/tmp

Hope this helps
