If you just want to identify logon attempts just pay attention to your
logwatch/ /var/log/secure or wherever you have it logging, if you want to
deny access I recommend an iptables rule based off quick connections to
port 22.  If you want to lock out I would look at pam_tally.

Feel free to ask questions about any of these.



Moreover, if you want to keep malicius conexions banned , like those which are 
trying to make a bruteforce attack, you could chek out fail2ban.
