No.  Cygwin relies on Windows for security information 
(that statement sound almost laughable when I re-read it! ;-) )

No.

Read http://cygwin.com/cygwin-ug-net/ntsec.html.  As a matter of 
fact, it would be good for you to review all the available documentation
at www.cygwin.com, the email archives, and documentation under /usr/doc
for any newbie questions.  Many of these have probably been asked before.
