Joe, a technician at the local power plant, notices that several turbines had ramped up in cycles during the
week. Further investigation by the system engineering team determined that a timed .exe file had been
uploaded to the system control console during a visit by international contractors.
Which of the following actions should Joe recommend?
Create a VLAN for the SCADA
Enable PKI for the MainFrame
Implement patch management
Implement stronger WPA2 Wireless
VLANs are used for traffic management. VLANs can be used to isolate traffic between network segments. This
can be accomplished by not defining a route between different VLANs or by specifying a deny filter between
certain VLANs (or certain members of a VLAN). Any network segment that doesn’t need to communicate with
another in order to accomplish a work task/function shouldn’t be able to do so.
