Restrict Router Use

IT Admin, Johnny

Issue:
Restrict rouge laptops from connecting to our network.

Details:
On some rare occasions, we have had some people come in and plug their
laptops into our network.

Since we utilize a pretty much open router, these laptops would have instant
internet access.

A couple of these laptops have been virus infected, and these viruses
brought down our router a couple of times due to their nature to do port
scanning on the network they are connected to.

We do not use a proxy server. We do use DHCP.

Question:
Is there a way to prevent these rouge systems from connecting and utilizing
our system, or to detect them when they are on? I imagine if we remove this
ability, people will quite plugging into our network.

You will need to secure the router with a list of "known" good network
adapters. Then, you only allow the list of "known" network adapters access
the the network (via DHCP???). If the "rouge" laptop tried to connect, it
should not get a valid IP.


BTW: Implement a network wide anti-virus solution so that every laptop/PC you
allow to be connected will get some protection from viruses. Also consider
Internet gateway anti-virus, so you are protected from incoming (from the
Internet) and outgoing (from your PCs/laptops).
