Further more, SSH can be resource hogger/intensive for your server too if not setup properly, in other words, it can use up all of your resources making the server unusable or rather taking the complete system down .. -
You can limit/prevent such applications and scripts to stay within the limits by setting up the
"Shell Resource Limits" for the users.
You can configure shell resource limits in
/etc/security/limits.conf on most Linux systems..
Note: Please make a backup of any files you modify, in case you change anything unexpectedly, restoring the system to the original state becomes easier...
