Connecting to public Wi-Fi can be very convenient, especially if you’re doing so in an area where cellular reception is less than reliable. But we should remember that there are risks associated with unknown networks, and these should be accounted for before you connect to them.
How public Wi‑Fi works and why it’s risky
When you connect to a public network, you don’t know who else might be using it. This grants an opportunity for malicious actors to intercept and exploit your data. You might think of a suspicious person hunched over a laptop in a café… but in most cases, hacks of this kind are performed remotely.
What data is most at risk
So, what kinds of data might a hacker seek to intercept and exploit? The most sensitive kinds of data are login credentials, which can be used to compromise your accounts. Personal details, like names, addresses, and browsing behavior might also be of interest to the average hacker.
Just as you wouldn’t reveal this kind of information in the real world, or broadcast it publicly, you’ll want to be very cautious about how you connect in the digital one. But exactly how might you do this?
Protecting yourself on public networks
When you’re connecting to a public network, you can protect your identity in a variety of different ways. Connecting via an encrypted service is essential, and this is something that most modern browsers offer as standard. You’ll also want to extend the power of your browser with the help of plugins and extensions. A VPN Chrome extension might allow you an additional layer of privacy that can be perfect for public WiFi.
It’s also a good idea to review the permissions you’re granting to your social media services, and to ensure that automatic updates are set up for your device. You’ll also want to verify the name of the network to which you’re connecting. Doing so might protect you against the so-called ‘evil twin’ attack.
Common mistakes users make on public Wi‑Fi
If you’re going to use public WiFi, then you’ll want to be aware of certain risks and take certain precautions. Turn off automatic connection, so that your device doesn’t automatically store and use login details without your knowledge. You’ll want to stay in control of how you’re connecting. Avoid accessing sensitive accounts, like your bank, when you’re connecting via networks of this kind.
Building safer habits for public browsing
Online security is rarely a simple matter of installing the right software and configuring your machine properly. It’s a matter of habit and behavior. Get into the routine of checking your connection, and being vigilant whenever you click on an unknown link. Some basic knowledge of the browsing tools provided by your operating system might also be worthwhile.
