What might make secure? (6)

I believe the answer is:

rescue

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

'what might' is the definition.
I can't judge whether this defines the answer.

'make secure?' is the wordplay.
'make' is an anagram indicator.
'secure' anagrammed gives 'RESCUE'.

Can you help me to learn more?

(Other definitions for rescue that I've seen before include "Deliver from harm" , "saving" , "liberation" , "Save someone from a dangerous situation" , "Retrieve" .)

I've seen this clue in The Sun.
