Introduction

The increasing reliance on wireless networks in both professional and personal contexts underscores the significance of robust wireless security measures. Home WLAN infrastructures, while facilitating seamless connectivity, are vulnerable to various security threats that can compromise private data, disrupt network functionality, or enable unauthorized access. Conducting a comprehensive security audit is thus essential to identify vulnerabilities, assess current security posture, and implement effective measures to safeguard the network. This paper presents a detailed wireless security audit of a personal WLAN, including a customizable audit checklist, audit results, analysis of security posture, and tailored recommendations to enhance security.

Developing a Wireless Security Audit Checklist

A wireless security audit checklist serves as a systematic guide to evaluate the security health of a WLAN. It comprises key areas such as device configuration, encryption protocols, authentication mechanisms, network monitoring, and physical security. The comprehensive checklist for a personal WLAN should encompass the following components:

1. Network Identification and Access Controls:

- Verify the SSID broadcasting status.

- Change default network names to non-identifiable names.

- Enable WPA3 or WPA2 encryption protocols.

- Disable WPS to prevent brute-force attacks.

- Implement strong, unique Wi-Fi passwords.

2. Device and Firmware Management:

- Update router firmware to latest versions.

- Disable remote management features unless necessary.

- Enable MAC address filtering for authorized devices.

3. Authentication and User Management:

- Use strong, complex passwords for admin interfaces.

- Set up guest networks with separate credentials.

- Enable multi-factor authentication if available.

4. Network Monitoring and Intrusion Detection:

- Enable logs and review them regularly.

- Use Intrusion Detection Systems (IDS) or network analyzers.

- Scan for rogue access points and unauthorized devices.

5. Physical Security Measures:

- Position the router centrally to minimize external reach.

- Secure physical access to network devices.

6. Additional Security Practices:

- Enable firewall features on the router.

- Disable UPnP if not needed.

- Conduct regular security assessments and vulnerability scans.

Creating a customized template based on the above points ensures a thorough investigation of the WLAN's security posture.

Selecting a WLAN Infrastructure and Permission

For the audit, a designated personal WLAN infrastructure will be examined—namely, a typical home Wi-Fi network consisting of a dual-band router supporting WPA3 encryption. Prior written permission has been obtained from the homeowner to conduct this security assessment, adhering to ethical standards and avoiding any privacy violations. This permission document confirms authorization to perform security testing within specified boundaries, ensuring compliance with legal and ethical frameworks.

Audit Results and Security Posture Analysis

The audit revealed several strengths and vulnerabilities within the identified WLAN. The network employs WPA3 encryption, which is currently the most secure Wi-Fi security protocol, effectively safeguarding against eavesdropping and unauthorized access. The router firmware is up-to-date, and the network does not broadcast the SSID, reducing external visibility. MAC address filtering is enabled, and administrative credentials are complex, aligning with best practices.

However, multiple weaknesses were identified:

- The default administrator username was unchanged, potentially exploitable via brute-force attacks.

- WPS was enabled, posing a security risk, as WPS vulnerabilities are well-documented.

- Guest network settings were improperly configured, allowing access to internal network resources.

- The router's remote management feature was enabled, exposing the network to external threats.

- Device logs were rarely reviewed, limiting intrusion detection capability.

- Physical placement of the router was near a window, increasing susceptibility to external signals.

These deficiencies expose the WLAN to risks such as unauthorized device access, man-in-the-middle attacks, and potential compromise of connected devices.

Recommendations to Improve Security

To strengthen the WLAN security posture, the following actions are recommended:

1. Change Default Credentials and Usernames:

- Replace default admin username with a non-standard name.

- Use a strong, complex password for router administrative access.

2. Disable Vulnerable Features:

- Turn off WPS and remote management features.

- Enable only necessary services and ports.

3. Enhance Network Segmentation:

- Properly configure guest networks to prevent access to the main network.

- Use VLANs if supported to isolate sensitive devices.

4. Implement Regular Monitoring:

- Enable and review logs periodically.

- Use network monitoring tools to detect rogue devices.

5. Physical Security Enhancements:

- Position the router indoors, away from windows and external walls.

- Secure physical access to network hardware.

6. Update Security Protocols and Encryption:

- Sustain WPA3 encryption and periodically change passwords.

- Consider implementing additional security layers such as VPNs for sensitive activities.

7. Educate Users and Conduct Routine Audits:

- Educate all network users about security best practices.

- Schedule regular security evaluations to promptly identify new vulnerabilities.

Adopting these measures will significantly mitigate vulnerabilities and improve the overall security framework of the home WLAN.

Conclusion

A comprehensive wireless security audit of a personal WLAN highlights the importance of proactive security management to protect sensitive data and maintain network integrity. While the network demonstrated adherence to key security practices such as WPA3 encryption and firmware updates, critical gaps related to administrative access, feature settings, and physical placement affect its resilience. Implementing targeted recommendations, including credential changes, disabling vulnerable features, enhancing monitoring, and physical security adjustments, will reinforce defenses against evolving threats. Regular audits and user education are essential for maintaining a robust security posture. This process exemplifies best practices for safeguarding personal WLANs in an interconnected environment.
