Newby question

[Francesco]

Hi,

i have just installed and configure INN; please let me ask you a few
questions:

- are there some critical security issue using INN? Is there a way to
protect INN server?

- i have configured a system which accept posting and reading by
authenticate users with ckpasswd; can i see to INN to give different
permission on various newsgroups according to the authenticated users? As
example, i would like to give to "Fred" read/post acces to some newsgroups
and to "John" read/post access to other newsgroups.

Thank you in advance for your kind interest, best regards!
