Where's the 'install from unknown sources' checkbox?

[smallpro]

I've updated my Xperia mini pro to ICS 4.0.4 Build 4.1.B.431 a few weeks ago. I just noticed that I can't find the checkbox to allow me install programs from unknown sources/not directly from market. When it was still Gingerbread, I can access the checkbox from Setting > Application. Can anyone tell me how can I access this checkbox in ICS?

setting > security
