Prevent search results and indexing of site

I have a site intented for visitors with the direct URL only. It will only have one or two pages. I need them (basically the whole site) to NOT be listed in search results or indexed by search engines. I've read that a "noindex directive" is the way to accomplish this reliably. Is it possible to make that happen in a SS site?  If not, what are the other options short of creating a password protected page? Password protection isn't going to work for my purposes. Thanks in advance!
