Easy network DOS's.

Easy physical access DOS's.

1.If you have access to the switches and you can unplug one cord from the wall and plug it so that both ends of the rj45 are in the switch, you can create a switching loop.

fix = Enable STP on your swithces.

2. Put a *nix machine on the same network, and change the IP of the machine to the IP of the default gateway.

fix = use 802.1x

3. Put a dhcp server on the network.

fix = again use 802.1x

4. On a complicated network use a low powered machine to arp poison all IP's.

fix = again use 802.1x. Use IDS solution.

5. Run Novell

fix = quit using Novell
