ISC2 CC Practice Question: Which THREE of the following are best practices…
Which THREE of the following are best practices for securing a wireless network?
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 SSID broadcast
WPA2 encryption, disabling SSID broadcast (though not strong, often considered best practice in older materials), and using a strong passphrase are commonly recommended. MAC filtering and captive portals are not primary security controls.
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 SSID broadcast
Why this is correct
Disabling SSID broadcast hides the network from casual scanning, though it is not a strong security measure.
- ✓
Use WPA2 encryption
Why this is correct
WPA2 provides strong encryption for wireless communications.
- ✗
Enable MAC address filtering
Why it's wrong here
MAC filtering can be easily spoofed and is not a reliable security control.
- ✓
Use a strong passphrase
Why this is correct
A strong passphrase prevents brute-force attacks on the pre-shared key.
- ✗
Implement a captive portal
Why it's wrong here
Captive portals are for user authentication, not for securing the wireless network itself.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
