Wi-Fi Security Tips
An insecure network in a bookstore, coffee shop, hotel or airport exposes the user not only to viruses and spyware but also potentially exposes information on the hard drive. iBAHN offers tips to protect assets while connected to a Wi-Fi network.
- Disable or block file sharing (and all other network services) on interfaces used for broadband access.
- Enable Windows Firewall or (preferably) install a third-party personal firewall.
- Use file encryption, available in Windows XP Professional and other products.
- Choose non-obvious passwords to deter notebook, data and server access.
- Use a VPN or encrypted mobile application, ideally with two-factor (hardware or biometric) authentication. Choose public Wi-Fi access that provides enhanced security services.
- Connect only to known SSIDs, using WPA/802.1X to verify the server's certificate.
- Disable ad-hoc mode and automated connection to non-preferred SSIDs.
- Use a host intrusion detection agent to detect/prevent risky connections, including bridging between wireless and wired interfaces.
