SECURITY Poll: How is it organized where you work?

I work in the Data Center Operation department, within the IT Division. Our department has just formed a NEW group within my department titled, ?Security?. I have been made part of this group (I?m not in charge). So far, I know they plan to have me help review process and procedures, and document.
I?ve been encourage to start some high-level research of my own.

For now I just want to see how other mid-size businesses built their IT Security Group.

Here?s what I?d like to collect from you (just high-level):

Role(s)
Responsibilities

Thanks ahead for any and all responses!
