Category wise access control

Question

In my company there are few department like IT, Developer, Marketing, Commercial, Finance etc. What I need is to restrict departmental question within the users those are added to the department. Such as if a question is asked with "IT" category then the question is only visible to the users those have the permission to "IT" category.

N.B. I never got any answer from this forum earlier :(

If every category is so different, what's the point of even having different categories? Why not use different Q2A sites?

If any of the topic is too much needed then it could be moved to General category for the access of everyone

This can very much be done but need a custom plugin for doing so. Every user needs to have a list of categories to which he has access.
