Is there a way to keep your Facebook account hacker free?

I was watching the view with my mom and they were talking about Facebook giving out personal and public information about you to other social networking websites.

I always set my Facebook accout to only my friends can see my “wall” but i still don’t want hackers on my profile.

So my question is, Is there a way to keep your Facebook account hacker free and your personal information secret and not let Facebook do that to let your information spill?
