What is the biggest security concern with wireless networks?

Question

Options

• AFirewall software is not available for access points.
• BWireless encryption algorithms must be implemented.
• CWireless networks do not support intrusion detection.
• DWireless networks do not support encryption via an access point.

• A
  14% (9)
• B
  74% (48)
• C
  9% (6)
• D
  3% (2)

Explanation

Wireless networks broadcast data through the air rather than through physical cables, making them inherently vulnerable to eavesdropping by anyone within signal range - so implementing strong encryption (WPA2, WPA3) is the fundamental security requirement that cannot be skipped. Option B is correct because the selection and proper implementation of encryption is the core challenge: weak algorithms (like WEP) or misconfigured encryption can leave the network just as exposed as no encryption at all.

Why the distractors are wrong:

• A is false - firewall software is absolutely available for access points; many APs have built-in firewall features.
• C is false - wireless intrusion detection systems (WIDS) exist and are widely deployed.
• D is false - access points do support encryption; WPA2/WPA3 encryption is typically enforced directly through the AP.

Memory tip: Think of a wireless network as shouting in a crowded room - anyone nearby can hear you. Encryption is the "secret language" that makes the broadcast useless to eavesdroppers. The concern isn't whether encryption exists, but whether it's properly chosen and configured.
