Guest Network Security

Measures to protect guest Wi-Fi networks from cyber threats and unauthorized access.

Understanding Guest networks

Isolated wireless networks that allow visitors to access the internet without compromising the main corporate or home network. Proper guest network security prevents unauthorized access, data interception, and malware infections.

Common Applications and Use Cases

Corporate Environments – Provides secure internet access for visitors and contractors.
Retail and Hospitality – Offers public Wi-Fi in cafes, hotels, and airports.
Educational Institutions – Enables students to access the internet without entering the institution’s internal network.

Best Practices and Security Considerations

Network Segmentation – Ensure guest networks are completely isolated from internal systems.
Enforce Strong Encryption (WPA3) – Avoid outdated security protocols like WEP or WPA.
Limit Bandwidth and Access Time – Prevent abuse and mitigate DoS attacks.
Enable Captive Portals – Require guest authentication or agreement to terms of use before granting access.
Monitor Guest Traffic – Use network intrusion detection systems (NIDS) to detect anomalies.
