Thanks. Then should I run the job as ssh remotenode -t "screen -S ServerFault /path/to/myjob &> /path/to/log " ?

I should mention that its couple of days I am running this script on my server every 20 minutes on my server. It works fine and has detected ~9 attacker from around the world.

comment ftp server to restrict 'get' and 'ls'
What kind of service this FTP server offers? If it is write only, you can change the permission of FTP sub-folder to 522 to achieve what you want.

comment Block brute-force attack using lastb and iptables
@lain: No. Why should this happen? My system's RSA key is stored in the authorized_keys on the server. Also, there is a threshold for the number of failed retires from specific IP. The threshold is set tresh=10 and can be larger to detect a brute-force attacker.

comment Block brute-force attack using lastb and iptables
My system is trusted to server and It connects through SSH passless connnection and would not be included in lastb log anyway. The script only blocks the last broken SSH logins not successful ones. +1 for Fail2ban. It looks interesting. Thanks.
