I currently use cisco 6000 switches & 2600 routers. I also have 'real secure' IDS but it's not yet implemented.

There are contractors working on our compound who require network access. We supply them with PCs however we recently discovered that they also plug in their personal laptops onto our lan ports.

Is there any system available that can detect & prevent such an occurence? Is this a feature available in the switches or do I require software

The most straight-forward way to do this is to record all the MAC addresses in use at your site (you can get them from the router arp caches), load them into the switches, and then shunt any unknown MAC's to a dead-end VLAN.

This not only keeps contractors/vendors from plugging in their own PC's, but also keeps employees from purchasing new systems that haven't gone through the "official" setup/purchasing process.

The other option is to implement something like Cisco's just-recently-released NAC product, which can do things like check whether machines have appropriate patches and anti-virus signatures, enforce that they are domain members, etc., etc.
