CND Network Attacks And Defense Strategies Practice Question
A security team is implementing defense-in-depth controls to protect an enterprise wireless network against advanced attacks. Which TWO advanced hardening and security configurations should be deployed? (Choose TWO)
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
✓
Mandatory Protected Management Frames (PMF / 802.11w) to prevent forged deauthentication and disassociation attacks.
Enterprise wireless security is enhanced by implementing WPA3-Enterprise with Protected Management Frames (PMF) to prevent deauthentication spoofing, and deploying Wireless Intrusion Detection Systems (WIDS/wIPS) to detect rogue APs and attacks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using Wired Equivalent Privacy (WEP) with static 40-bit pre-shared keys.
Why it's wrong here
WEP is obsolete, easily cracked in minutes, and should never be used.
- ✗
Configuring hidden SSIDs across all access points as the primary perimeter defense mechanism.
Why it's wrong here
Hidden SSIDs provide zero security as probe requests reveal SSID names immediately.
- ✓
Mandatory Protected Management Frames (PMF / 802.11w) to prevent forged deauthentication and disassociation attacks.
Why this is correct
PMF cryptographically protects management frames against spoofing and deauth attacks.
- ✗
Disabling all encryption ciphers to maximize wireless throughput and signal range.
Why it's wrong here
Disabling encryption leaves all wireless traffic completely in the clear, violating security policy.
- ✓
Wireless Intrusion Detection Systems (WIDS / wIPS) to monitor radio frequencies and alert on rogue APs or MAC spoofing.
Why this is correct
wIPS solutions detect unauthorized wireless activity, rogue APs, and wireless attacks.
