A security administrator is reviewing logs and notices multiple attempts to access the HVAC
controls by a workstation with an IP address from the open wireless network. Which of the
following would be the best way to prevent this type of attack from occurring again?
A.
Implement VLANs to separate the HVAC
B.
Enable WPA2 security for the wireless network
C.
Install a HIDS to protect the HVAC system
D.
Enable Mac filtering for the wireless network
Answer is C.
I think the answer is A, by implementing a VLAN the open wireless network and HVAC unit controls are separated. A HIDS would only monitor the situation. MAC filtering is not viable in an open wireless network.
I believe it’s “A”. If you enable MAC filtering on the wireless network then it’s not really a “open wireless network” anymore. If that’s the case you might as well enable WPA2.
agreed. the answer is clearly A
