protected page

A protected page is one that requires special permission to change. An archived page is one example that should not usually be changed at all after it has been finally archived.

To protect pages requires admin authority.

Commonly protected pages are those that explain policies that are not subject to debate by edit, e.g. Terms of Use.

There are also temporarily protected pages including those that are so controversial that a wiki truce is enforced on them - no edits are permitted until each side has a chance to address each other's concerns, typically by email, chat or talk pages.
