non business equipment policy

Hi Guys,

We are having a few problems here at the moment with external equipment (i.e. laptops) being plugged into our network which contain viruses and worms… in particular the blaster worm which took down a fair chunk of our computers. What kinds of policies do you use in your corporate networks? Is it a case of not allowing any external equipment onto the network or to have it checked out first, or is your network secure enough to handle any virus ridden laptops in the first place?
