Any suggestions for making site secure?

Yesterday I was contacted by a friend who found her site had been hacked. Their password was a combination of letters and numbers and 14 in length. They updated the password to the maximum amount and changed all email passwords as well.

Someone told me there was a way to make a webpage more secure...besides increasing the password size, what other options are available?

Any help would be appreciated. Thanks!
