Question

A security team has identified that the wireless signal is broadcasting into the parking lot. To reduce the risk of an attack against the wireless network from the parking lot, which of the following controls should be used? (Select TWO).

Options

  • AAntenna placement
  • BInterference
  • CUse WEP
  • DSingle Sign on
  • EDisable the SSID
  • FPower levels

Why each option

To limit wireless signal bleed into the parking lot, adjusting antenna placement and reducing transmit power levels are the two most effective physical controls that directly reduce signal range.

AAntenna placementCorrect

Antenna placement determines the direction and coverage area of the wireless signal; repositioning or using directional antennas can focus the signal away from the parking lot. Combined with adjusting power levels (F), organizations can tune the exact coverage footprint to prevent signal from reaching unintended areas.

BInterference

Introducing interference would degrade the wireless network for legitimate users and is not a recognized security control.

CUse WEP

WEP is a deprecated and easily cracked encryption protocol that does not reduce signal range.

DSingle Sign on

Single Sign-On is an authentication mechanism and has no effect on wireless signal coverage.

EDisable the SSID

Disabling the SSID broadcast hides the network name but does not reduce the physical range of the wireless signal.

FPower levelsCorrect
