Security measure that adds spice (6,5)

'security' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'measure that adds spice' is the wordplay.
I cannot really see how this works, but
'measure' could be 's' (S is an example) and 's' is found in the answer.
'spice' could be 'pepper' (peppering is a kind of spicing) and 'pepper' is located in the answer.
The remaining letters 'pray' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
