Hello, I have a question

[Aleksandr Rybev]

Hello,
I have a question.  I would really appreciate  if you could please help.  
How to view and to know how many restricted bugs associated to a specific group. (For example:  we have created IT group for IT users. We would like to know how many restricted bugs associated to IT group) in Bugzilla.
I am wondering if it could be via mysql query or via Bugzilla Gui interface.

Thank you in advance,

Sincerely ,
Aleks
