ENUM alternatives

Question

Is there a more efficient way of preventing users from editing a form text via firebug then posting the custom values? I've heard quite a bit about not using ENUM's with large data sets. How else can i limit my users and prevent them from editing my forms to post altered data? An example would be a list of countries.

Thanks

You can never be sure of what is happening on the client side, firebug, greasemonkey they all give users power to do anything they wish. To be sure validate form on the server side too.
