Login attacks

[Michael Yep]

Hello

In my LogWatch report I get many login attacks, many from the same IP address.

sshd:
    Authentication Failures:
       root (218.232.109.187): 59 Time(s)
       adm (218.232.109.187): 2 Time(s)
       apache (218.232.109.187): 1 Time(s)
       nobody (218.232.109.187): 1 Time(s)
       operator (218.232.109.187): 1 Time(s)
    Invalid Users:
       Unknown Account: 43 Time(s)

I have permitRootLogin set to NO, and I use strong passwords, but can I 
just add these IP addresses to hosts.deny?
and if so how would I set that up
