“We work through the user’s role … so we

become familiar with particular department’s

user activities.”Security Manager

“At a high level we are aware. At the detailed

process level really only when we are doing a

project in that department. When we need to

understand the process within the project.”

To validate the model

“This model will be relevant to any business.

I don’t think many have considered practically

addressing this dimension of security in their

organisations.”

implement a technology solution .... The cost of

such implementation would be justified by you

model. It will save user’s time and you can get

security benefit as well.”
