To do a basic check of what ports are open from a particular machine I highly recommend the ShieldsUp! utility on www.grc.com which needs you initially to OK connection to your PC then probes all 65535 ports and produces a report of what it could and couldn't connect to. With a firewall such as Zone Alarm in Windows the result was "no ports open, everything running in Stealth mode." Running that from a networked PC you can get a rough idea of what the perimeter security is like, but as Simon said that's probably the last place to look. I recently did a report for University on a mythical company that had net access and wanted to increase their security. Possibly I went a bit far as a SysAdmin friend looked at my 12 recommendations and said "err.. I think we do three of them!" ;) Kind regards, Julian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDs8dTjs/5IBdCO1ERApeVAJ4iLwSuHfHftwulTinH9l/BSaKC4ACffGFX 0GQ1hHJfOPzI8C9fB8fxaq4= =XGJM -----END PGP SIGNATURE----- -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
