With this detailed physical security assessment complete, we can now move on to evaluating the network configuration of these access points.

Network Configuration Evaluation

A. Verify SSID settings and naming conventions

When evaluating network configuration, start by examining the Service Set Identifier (SSID) settings and naming conventions. A well-structured SSID strategy is crucial for network organization and security. Consider the following aspects:

• SSID visibility (hidden vs. broadcast)
• Naming conventions for different networks (e.g., guest, corporate)
• Use of multiple SSIDs for network segmentation

SSID Type	Example Name	Purpose
Corporate	CORP_SECURE	Secure access for employees
Guest	GUEST_WIFI	Limited access for visitors
IoT	IOT_NETWORK	Isolated network for devices

B. Check encryption protocols and key management

Next, assess the encryption protocols in use and the key management practices. Strong encryption is essential for protecting wireless communications from eavesdropping and unauthorized access.

• Verify the use of WPA3 or at least WPA2 encryption
• Check for deprecated protocols like WEP or WPA
• Evaluate key rotation policies and practices

C. Evaluate authentication methods

Authentication methods play a crucial role in ensuring only authorized users can access the network. Review the following:

• Use of 802.1X/EAP for enterprise-grade authentication
• Implementation of captive portals for guest access
• Integration with centralized authentication systems (e.g., RADIUS)

D. Assess VLAN configuration

Virtual Local Area Network (VLAN) configuration is vital for network segmentation and security. Examine:

• Proper VLAN assignment for different SSIDs
• Isolation between guest and corporate networks
• Use of dynamic VLAN assignment based on user roles

E. Review QoS settings

Quality of Service (QoS) settings ensure critical applications receive priority. Evaluate:

• QoS policies for voice and video traffic
• Bandwidth allocation for different SSIDs
• Application-based prioritization

With these configuration aspects thoroughly evaluated, you can move on to analyzing the performance and coverage of your wireless network.

Performance and Coverage Analysis

Conduct site survey for signal strength

A comprehensive site survey is crucial for assessing wireless access point performance. Use specialized tools to measure signal strength across the coverage area, creating a heatmap to visualize dead zones and areas of strong connectivity.

Measure throughput and data rates

Evaluate the actual data transfer speeds and network capacity using network testing tools. Compare the results against the advertised specifications of your access points.

Metric	Target	Actual	Status
Download Speed	100 Mbps	95 Mbps	✅
Upload Speed	50 Mbps	48 Mbps	✅
Latency	＜20 ms	15 ms	✅

Identify interference sources

Detect and document potential sources of interference that may impact wireless performance:
