I guess my opinion, which isn't very popular
here, is that unless
permission has been explicitly given, one should not assume permission
to a local LAN, or internet access through the LAN. I do recognize
that my position is due to working frequently at secured sites. One
such facility, in San Antonio, prohibits ANY access to their network
by non-employees. Contractors must tell a technician what commands to
enter, and which buttons to click.
Of course, there is a conceptually simple way to prevent 99.9% of people
from accessing a lan in this kind of situation. Wire
the wall-mounted RJ45
jacks to use the normally unused pairs for TX/RX, and use
custom made
patch cables to connect to the computer's NIC. For some ultra-secure type
site, wiring the other two pairs to detect a connection, and or to deliver
48VDC (from a spare telephone switch supply) would deter all but the most
determined.
