Is there any dataset available of Facebook users which shows how people are connected with each other? So that I can use that dataset to do some research on access control in social networks.

Facebook has the Graph API so you can construct your own queries and collect as much data as you want.
Otherwise, there are some collected resources described in this thread (warning: from 2010 and maybe involving hacked data).
If you don't require Facebook, there are much better resources for Twitter (datasets and public search/stream API access)
