ISC2 CC Practice Question: Which TWO of the following are best practices for…
Which TWO of the following are best practices for securing a wireless network? (Select exactly two.)
⚠ Common exam trap
ISC2 often tests the misconception that hiding the SSID or using static IPs are effective security measures, when in fact they are easily bypassed and do not protect against modern wireless attacks.
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
✓
Implement MAC address filtering
MAC address filtering restricts network access to devices with pre-approved MAC addresses, adding a layer of access control. While not foolproof (MACs can be spoofed), it is a recognized best practice for reducing the attack surface in small or home networks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use WEP encryption for compatibility
Why it's wrong here
WEP is deprecated and easily cracked.
- ✗
Disable SSID broadcast
Why it's wrong here
Disabling SSID broadcast is a weak security measure as attackers can discover the SSID easily.
- ✓
Implement MAC address filtering
Why this is correct
MAC filtering can restrict which devices can connect, though it can be spoofed.
- ✗
Disable DHCP and use static IP addressing
Why it's wrong here
Static IP addressing does not prevent unauthorized access and adds administrative burden.
- ✓
Enable WPA3 encryption
Why this is correct
WPA3 is the latest and most secure Wi-Fi encryption standard.
Quick reference
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 |
