CISSP

Talking abou CISSP, I have some certs from Cisco,Checkpoint,SUN and soom to
IBM and Compaq tru64. But I want real bad CISSP. Although I dont have those
3 years (which will be expanded to four plus degree) of experience in the
market.
Does anyone know if I could still take CISSP or will my appliance fail? If
it does, what kind of comprovation do they need? May I just say I worked but
dont prove anything? I have 4 months programmimer experience, 6 months
sysadmin, and some months from non professional work. Btw, im in brazil.

Thanks in advance
