Is there a security concern exposing NTLM authentication over http or should it only be https?

https

We are setting up a SharePoint 2010 site. Don't worry, this is not a Sharepoint question, just adding it for context. Most of the site will be anonymous, but some users are able to authenticate in and edit content. They use NTLM (users exist in AD). Is there any concern about exposing NTLM login for users that can modify content over the internet via http or should that only be exposed via https?
