WebApp Sec: Authorization Framework.

[Babu Kopparam <babukopparam () gmail com>]

Hi! Experts,

I am working for product company which own around 80 products.
My role is to provide security framework to all the teams.

I have proposed RBAC (referring NIST's specification) as the suitable
solution for Authorization.

I want to know if my selection is right OR is there any other widely
used method.

Can you provide some links to gather more information about the same.

Thanks in advance,
-Babu.
