Protection from rising draughts? (5)

Ross

I believe the answer is:

guard

I'm a little stuck... Click here to teach me more about this clue!

'protection' is the definition.
(I've seen this before)

'rising draughts?' is the wordplay.
'GUARD' is hidden backwards in amongst the letters.
But, I am uncertain how this is indicated.

'from' acts as a link.

Can you help me to learn more?

(Other definitions for guard that I've seen before include "state of caution" , "Yeomen" , "See 1" , "One keeps watch" , "Sentry" .)

I've seen this clue in the Evening Standard.
