I have found that lots of attackers using /tmp or /dev/shm to save 
and execute backdoor. So I would like to secure this directory..

I opened /etc/fstab file and added noexec, nosuid option and remounted.

On FreeBSD I've always set /tmp this way:

/dev/ad0s1e             /tmp            ufs     rw,nosuid,nodev         2       2
