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
