"For that reason, it is vital to XX Agency security and legal posture
(no Federal Agency has been successful to date in prosecuting a
perpetrator without the presence of Warning Banners) "
from http://csrc.nist.gov/fasp/FASPDocs/
logaccess-control/ScreenBanner-Paper.doc

This is so well put I'll just copy it.
"Part of the reason for a logon warning banner is to identify your
systems legal restrictions and rules of access. It has been
successfully argued in court that if the system provider did not put
up a warning banner, they had no legal recourse. Especially if, as
many default banners used to be, the banner as "WELCOME". Arguably, an
unsecured AP is a "WELCOME"."
from http://securityfocus.com/comments/articles/9606/28682/threaded

I'm trying to find the actual case, but some time ago there was a
hacker that was let off because the system he hacked said "WELCOME TO"
then the system name and he argued they were welcoming him in. The
idea is without a warning banner the hacker can argue he got in and
didn't know he shouldn't be there. A warning banner blatently says "go
away" and such arguments are therefore invalid right away.

Can someone point me to the statues that govern the need for remote
access warning banners, such as those used on telnet or ftp servers?
Are there any cases where a banner was not used, and consequently an
attacker was not successfully prosecuted or/and got a reduced
sentence?
