Wireless access of clients to the Certkiller .com network has to be secured as Certkiller .com is in
a large office complex. The best way to do this would be ______. Select the correct answer from
below.
A.
Install a security firewall.
B.
Implement biometric access control.
C.
Reduce the signal strength.
D.
Disable SSIP broadcasts.
Explanation:
Most wireless access points (APs) and routers automatically transmit their network name (SSID)
into open air at regular intervals (every few seconds). This feature of Wi-Fi network protocols is
intended to allow clients to dynamically discover and roam between WLANs. However, this feature
also makes it easier for hackers to break into your home network. Because SSIDs are not
encrypted or otherwise scrambled, it becomes easy to grab one by snooping the WLAN looking for
SSID broadcast messages coming from the router or AP. Knowing your SSID brings hackers one
step closer to a successful intrusion.
