Niekoniecznie.

1999 Oregon Revised Statutes (see Computer Crime, Section
164.337):

(4) Any person who knowingly and without authorization uses, accesses,
or attempts to access any computer, computer
system, computer network, or any computer software, program,
documentation or data contained in such computer, computer
system or computer network, commits computer crime.

DNSOnline, an ISP in Plymouth, IN,
addresses scanning in their Acceptable Use Policy as follows:

a. Port Scanning

Port Scanning of any DNS computer will be considered a
preliminary to a hacking attempt
and is therefore expressly forbidden. DNS will immediately
terminate the account of any
Customer found to be port scanning the DNS system. A first-time
offender will be allowed to
reopen an account with DNS only after paying a reconnect fee of
$50.00. Repeat offenders
will not be allowed to reopen an account with DNS; moreover,
their names and account status
will be posted on a DNS web page for area residents and other
ISPs to check.[1]

Port scans

Attempting to find vulnerable computers, malicious users methodically
port scan IP addresses.
It is likely that even dial up modem users get scanned several times a
day if on for long periods
of time.

"A port scan is a series of messages sent by someone attempting to
break into a computer to
learn which computer network services, each associated with a
"well-known" port number, the
computer provides. Port scanning, a favorite approach of computer
crackers, gives the
assailant an idea where to probe for weaknesses. Essentially, a port
scan consists of sending a
message to each port, one at a time. The kind of response received
indicates whether the port
is used and can therefore be probed for weakness."

1) Any more, 9 out of 10 port scans represents a script kiddie that has
taken over a machine and is using it to find another. As a network
administrator, I most certainly want to know if people are seeing a
machine
under my control performing these scans. If you guys EVER see a port
scan
coming out of a network I own, please, please let me know.

2) The activity in question has but one purpose, to find a computer to
be
exploited. Semantic/legal arguments abound on this subject, but many of
us
feel that intent to commit a crime constitutes a crime. In many
localities,
unauthorized intrusions into a computer network represent a crime. If I
see
someone repeatedly driving down my street looking for houses to rob,
the
police tell me I should report it as suspcious activity. If I see
someone
hanging around a school yard in a trenchcoat in the middle of summer
looking
at the little girls (or boys) on the playground, I think I should
probably
report that too. Define, please, the difference. If the job of policing
your network is too hard for you, perhaps you are understaffed or in
the
wrong occupation.

3) It's only part of being on the net if we allow it to become so. See
SPAM
for a comparison -- "Just hit delete" means that everyone with a herbal
suppliment to sell gets to flood my mailbox with relative impunity.
"Just
write it off as being part of the net" means that I can never be sure
of my
network's security. I will never accept that.

4) My network is my (or my company's) property. Intrusions and
intrusion
attempts are tresspassing. I reserve the right to allow my dobermans to
bark at people trespassing on my property.
