Secure place in which to keep a hack? (6)

I believe the answer is:
stable
This might be a double definition.
'secure' is the first definition.
(I've seen this before)
'place in which to keep a hack?' is the second definition.
'stable' can be an answer for 'place' (I have seen 'Place of birth' mean 'stable' so perhaps 'place' could also mean 'stable'). I'm unsure of the rest of the definition.
Can you help me to learn more?
(Other definitions for stable that I've seen before include "container for punch, for instance" , "Settled; animal shed" , "Horse barn" , "Steady, enduring" , "Firmly balanced or fixed" .)
