• Purchase products only from un-authorised vendors

What can we implement to help limit unnecessary lateral communication across the network?

• Implement static DHCP across the network

• Allow workstation to workstation communication

Once an intruder establishes an effective beachhead within the network, unfiltered lateral communications allow the intruder to create ********* throughout the network.

What would a segmented star toplogy look like?
