Hi All,

download undesirable programs i.e. adult. my boss has asked me to block
such things happening again. does anyone know which ports these programs
use?


Many thanks

Install a proxy server and turn on filtering.

Rather than try and block ports, most P2P use a range of alternative

alternating ports, as does MSN Messenger, try
enforcing the rules by using a stern email CC'd to the management warning
users, there are free tools that can scan entire
domains and look for files within a set range such as JPG MOV MPG GIF, also
some tools can find EXE files that don't fall into a predetermined range,
set the software to look for the most obvious such as Imesh Kazaa, Gnutella,
Bit torrent.

It is a difficult task to enforce what users can and will install, but if
you sack just one person for gross misconduct then
the rest will get the message.

Most companies have an email usage policy as i'm sure yours does, send this
out regularly and when someone breaks the rules
they will have no, "I didn't know" defence.

Blocking is the wrong approach. You should have a user policy that forbids
users to do what they have been doing. If you open the firewall on port 80
for internet surfing, any decent P2P program can use that port and bypass
your firewall. Then you have to implement packet filtering... then that is
bypassed... then you have to take the next step. It never stops. A policy
tells people what they company rules are for internet usage. Your employees
sign that. If they don't adhere to it, they can eventually get fired.
Simple. It's all about education and good manners in the workplace, not
about putting up roadblocks and obstacles. Eventually it costs a lot of
money as well...
