Means of limiting fraud and corruption involving staff (11)

I believe the answer is:

containment

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

'means of limiting' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'fraud and corruption involving staff' is the wordplay.
I cannot really understand how this works, but
'fraud' could be 'con' (con is a kind of fraud) and 'con' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
'staff' could be 'men' (I've seen this in other clues) and 'men' is found within the answer.
The remaining letters 'tait' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for containment that I've seen before include "defensive policy" , "Action of keeping something harmful under control" .)
