Secure /tmp and /var/tmp on a OpenVZ VPS

How do I secure /tmp and /var/tmp on a OpenVZ VPS?

On an OpenVZ VPS you will need to do the following to secure /tmp and /var/tmp.Secure /tmp
===================================================================

1. Edit /etc/fstab by typing the command nano -w /etc/fstab
2. Paste the following at the bottom of /etc/stab that you just opened: none /tmp tmpfs nodev,nosuid,noexec 0 0
3. Press ctrl + x to close the file, press y to save it.
4. Remount /tmp by typing the following then press enter: mount -o remount /tmp
5. You can verify that /tmp is correctly mounted by typing df -h and you should see something similar to the following: none          3.9G   0  3.9MG   0% /tmp

=====================================================================
    Secure /var/tmp

1. Backup /var/tmp by typing the following: mv /var/tmp /var/tmpbackup
2. Make a symbolic link that makes /var/tmp point to /tmp by typing the following: ln -s /tmp /var/tmp
3. Copy back the old data using the command: cp /var/tmpbackup/* /tmp/
4. Remove the un-needed backup you created: rm -rf /var/tmpbackup

======================================================================
You should now reboot your VPS. This means /tmp and /var/tmp are now secured.
