Verify the Network
Always confirm the correct network name with airport staff. If the network information is not readily available, check the airport’s official website for details on their WiFi offerings.
Turn Off Sharing Settings
Before connecting to any public WiFi network, ensure that file sharing and public folder sharing settings are disabled. This prevents unauthorized users from accessing your files or data.
Use HTTPS Websites
When browsing online, ensure the websites you are visiting use HTTPS rather than HTTP. The “S” indicates that the website is secure, providing an extra layer of security against potential snooping.
Forget the Network
Once you are done using the airport WiFi, ensure that your device ‘forgets’ the network. This action prevents your device from automatically reconnecting in the future, minimizing any security risks.
Signs of a Suspicious Network
While the allure of airport WiFi is undeniable, it’s crucial to remain vigilant and aware of potential threats. Here are a couple of indicators that a network might be unsafe:
Poor Signal Quality
If the signal is weak or frequently disconnects, it may indicate that the network is overloaded or improperly configured, which can happen with rogue hotspots.
