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
  3% (1)
• B
  95% (35)
• D
  3% (1)

Explanation

Wireless encryption algorithms must be implemented correctly because without proper encryption (like WPA2/WPA3), all wireless traffic travels through the air where anyone within range can intercept and read it - making encryption the foundational security requirement for any wireless network.

Why the distractors are wrong:

• A is false - firewall software is available for access points and is commonly used.
• C is false - wireless networks do support intrusion detection systems (wireless IDS/IPS solutions exist).
• D is false - access points absolutely support encryption; in fact, configuring encryption on the access point is the standard practice.

Memory tip: Think "air = exposed." Unlike wired networks where data travels through physical cables, wireless data floats through open air. Encryption is the only thing standing between your data and anyone with an antenna nearby - making it the biggest concern, not optional extras like firewalls.
