4 Tips to Stay Secure when using Public Wi-Fi

Travel is becoming more popular these days. You can travel to far-off places to enjoy a getaway or simply go to the local café to enjoy the atmosphere. It's the perfect time to revisit old familiar practices, too.


Like everything else we have to learn (how do you make small talk work again? ) Good practices for security on Wi-Fi networks may require a bit of a refresher, too.


You may be seen by others, which is an issue of privacy and security. These are four tips to keep you safe when you're out and about.


Be mindful about what networks you join

The first step is to be aware of the public networks you decide to join. Anyone can check the traffic that's being sent through a network. They just have to install a software that scans data packets on their computer. Transmit unencrypted data on an online site and your personal information goes up for grabs.


Avoiding open networks run by unknown administrators should be your main objective. You want to pass over obvious bad apples. Airports, department stores and hotels are more reliable than other establishments. They don't have Wi-Fi to spy on users. (At least not with the intention of sussing out residence addresses, credit card info, national ID numbers, and the like.) Pay attention to spellings of network names. Beware of fakes.


Are you unsure if the official Wi-Fi at your place? While the majority of Wi-Fi networks owned by large organizations require you to sign conditions before being allowed to use the network, small-scale businesses that have the resources to share your password with patrons will not require it.


But since anyone on a network can sniff its communications, you require additional security. These are the three remaining tips in this article. And remember, any network accessible by the public counts as public Wi-Fi, even if users need to pay for access (like in airports or hotels).


Make sure your firewall is turned on


Leaving your computer's TCP and UDP ports open is similar to leaving your home's external doors open and unlocked. To guard against intrusion, you want something that blocks these ports from traffic requests-effectively blocking view of the doors, so that nobody can enter and touch the doorknobs. That's what firewall software does.


In Windows 10 and 11, your PC should have a firewall turned on by default. However, if you've been messing around with your settings, be sure it's still on prior to connecting to Wi-Fi in public. Simply open your Settings app and search for Firewall & Network Protection into the search field.


Use HTTPS everywhere


Be sure to visit websites that transfer data over encrypted connections. Modern websites should use this kind of secure connection, but some older (or completely malicious) websites don't.


Your browser should notify you that you're not, however, you can manually check as well. Look for https at the beginning of the address.


Instead, you can make use of an unsecure HTTP connection (notice the absence of an "s") to exchange traffic with the site. Anyone on your network can see the traffic. This includes sensitive information like user names, passwords, payment info addresses, etc. (This Cloudflare page explains how this works in more detail.)


It is important to realize that when you use public Wi-Fi, it is sharing your network with many people who are able to see what you are doing. Without knowing who is trying to harm you. By conducting your browsing over secured connections, you won't stick out as a potential target.


To protect yourself For additional security, you can install to protect yourself, you can install the HTTPS Everywhere extension from the Electronic Freedom Foundation. It is available for Chrome, Firefox, Edge, and other browsers, and further minimizes unintentional use of unsecure websites.


Install a VPN


As we've mentioned, public Wi-Fi users can't see details of the data exchanged when you visit secure websites. However, they can see that you're on that website.


If you're using Google or just wasting time on TikTok Perhaps you're not worried. But step that up to checking your bank account balance on your PC or phone and the stakes are raised.


The best overall VPN


You don't have time to get home to take care of certain business. To protect your privacy, you can route your PC or smartphone's internet activity via virtual private networks (VPN). To make use of one, first connect to the Wi-Fiand then to the VPN. Once both connections are established, you can continue with normal internet browsing. All your internet traffic passes through the VPN's servers-someone monitoring network traffic only will be able to see your computer sending and receiving data through the VPN not the websites and services you visit during that session.


This strategy won't work if you aren't confident in your VPN. The majority of free VPNs aren't trustworthy and they often don't protect your privacy as well as paid services. Only use vetted services like those listed in our top free VPN roundup. You should upgrade to one of our recommended VPN services for paid use to enjoy faster speeds and access to more servers across the world. If you travel internationally, you'll require access to worldwide servers. Wow is life If you don't have local servers, your internet browsing experience will be slowed due to having to route your data across the ocean.
