GSEC Wireless Network Security Practice Question
Which THREE of the following actions are considered best practices when hardening an enterprise wireless infrastructure?
⚠ Common exam trap
Candidates often select 'Disable SSID broadcasting' as a best practice, which is ineffective security through obscurity, rather than focusing on robust authentication like 802.1X or WPA3.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disable WPS on all wireless access points.
Hardening a wireless network requires a layered defense approach. Disabling unused features like WPS prevents direct exploitation, implementing WPA3 or WPA2-Enterprise ensures strong cryptographic bounds, and using a Wireless Intrusion Prevention System (WIPS) allows for the continuous monitoring and mitigation of rogue devices. These three steps cover the primary vectors of wireless attack: protocol flaws, weak authentication, and unauthorized infrastructure deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Disable WPS on all wireless access points.
Why this is correct
WPS is inherently insecure due to design flaws in the PIN exchange process. Disabling it completely eliminates this attack vector, which is a mandatory step for any secure deployment. Failure to disable WPS leaves the network vulnerable to rapid credential recovery through automated brute-force tools.
- ✓
Implement WPA3 or WPA2-Enterprise with 802.1X.
Why this is correct
WPA3 provides superior encryption and forward secrecy, while WPA2-Enterprise with 802.1X mandates individual user authentication. Both methods are superior to PSK-based systems, as they eliminate shared credentials and significantly raise the bar for attackers attempting to compromise individual wireless sessions or the network as a whole.
- ✗
Enable SSID hiding to conceal the network.
Why it's wrong here
SSID hiding is not a valid security control as network names are easily discovered through passive packet capture. Relying on this gives administrators a false sense of security, while doing nothing to stop unauthorized access or reconnaissance by attackers who understand how 802.11 management frames operate.
- ✓
Deploy a WIPS for continuous monitoring and rogue detection.
Why this is correct
A WIPS is essential for detecting unauthorized access points, man-in-the-middle attempts, and denial-of-service attacks. By providing real-time visibility into the radio spectrum, it allows security teams to respond to threats that standard firewalls or endpoint security solutions cannot see, making it vital for wireless network integrity.
- ✗
Use WEP for legacy hardware compatibility.
Why it's wrong here
WEP is cryptographically broken and should never be used. Its implementation of RC4 is fundamentally flawed, allowing attackers to recover the key in seconds by capturing a small amount of traffic. Any network using WEP is effectively unencrypted and fully exposed to any local attacker monitoring traffic.
