Using Sitecore 8, build 3, MVC. I have a page (yourDomain.com\MustBeSecure) on a Sitecore 8 site and I do NOT want any users to access this unless they are in a specific security group ("sitecore\IhaveAccess").
I've looked into Content Editor for the item, clicked on the Security profile tab but believe that is for content editing.
Any help is appreciated on this.
///////// Update - Now working ///////// I should have noted we are using Active Directory with auto authentication. Per Martin's post I started looking @ Access viewer
** please note on these screen shots I overlay the actual names of the pages (and group name) to test-page and secure page (and IHaveAccess)**.
Thanks for the assistance!!
