Crossword Genius

A carefulness I cultivated for security (4,9)

Ross

I believe the answer is:

life assurance

'security' is the definition.
(life assurance is a kind of security)

'a carefulness i cultivated' is the wordplay.
'cultivated' indicates anagramming the letters.
'a'+'carefulness'+'i'='acarefulnessi'
'acarefulnessi' is an anagram of 'LIFE ASSURANCE'.

'for' acts as a link.
