So, who gonna stay idle when they are in a public Wi-fi hotspot zone, especially at work place, and just want to save data on their phone or laptop. But, they don’t bother about security. So, lets read how to be safe on public Wi-fi networks.
1. Practice Good Internet Hygiene.
The best piece of advice we can give you that without any software and tools, that promise to protect your privacy, is to practice good internet hygiene. Should avoid using online—sensitive data when you’re using unsecured, public Wi-Fi. It may be a good time to check the news or read your favorite blogs, but it’s not the best time to do your online banking.
Of course, if you have methods to secure yourself like the things we mention below, you can go little easier in this regard, but remember, however surfing on public Wi-fi networks is not that safe at all. It must always concern of privacy.
2. Avoid the bad networks.
Not every public Wi-Fi networks are same. For example, that “Free Airport Wi-Fi” network lurking in the background is undoubtedly worse than any Wi-Fi network provided by one of the coffee shops, stores, or retailers.
If you’re curious, you can use tools like WiFox and its mobile apps to map out networks and choose which ones to use and when. It needs to be said, if there are questionable networks like “Free Wi-Fi Here!” or “Absolutely Free Internet!” you should probably avoid them.
3. Little easy with semi-Open Wi-Fi Networks.
It may safe to use “semi-open” Wi-Fi instead of completely open networks, that have hidden SSIDs or put their passwords on receipts (stores, shops and libraries) instead of giving them out freely, and so on. Sometimes tools like Wi-Fox, which we mentioned above, have those in their database. Alternatively, there’s nothing wrong with just asking at the stores, shops and library’s counter.
4. Don’t use File Sharing and AirDrop Options.
You may not be able to control who’s on what network you’re using, but you can control your computer. Your computer probably has some file sharing options that assume you’re on a trusted network, with other trusted computers. Turn off file sharing in Windows and macOS, enable your system’s built-in firewalls, and keep internet-connected apps and services to a minimum. Mac users, take the extra step and set AirDrop to contacts-only.
5. Turn-on Wi-fi only when needed.
One of the basic rules of security is that if you don’t need something connected to a network, don’t connect it. Don’t forget turn-off your device’s Wi-fi after you have done working online. It’s a best practice good internet hygiene and it’ll also save your battery.
You can take this a step further and download local copies of your email and documents to work with when you don’t have a connection, or use Google Drive offline (or a similar service) to work without internet access, or just grab that movie or playlist to listen to when you’re not connected at all.
6. Always be up to date with your Antivirus and Antimalware.
While using public, untrusted networks, make sure your device is running some kind of antimalware and antivirus utility as well. Like Avira for Windows and Sophos for macOS (it’s also available for Windows). Whatever you choose to use, keep it up to date, and keep it running—especially when you’re out and about. Public Wi-Fi networks have been known to inject ads while you browse, and we all know how bad malvertising can be.
7. Install Privacy-Protecting Extensions in Browser.
Antimalware is great, but it only really protects you from things you download and execute, but not from malvertising. probably already use an ad blocker, but a good, customizable one like uBlock Origin gives you control over what’s blocked and what isn’t when you want it, and can lock out just about anything when you need it to. Disconnect is another great option, and protects you from same-network attacks like session hijacking and clickjacking—both of which are still real threats, and can give people access to things like your Amazon account or Facebook account, even if you’re browsing securely.
8. Use HTTPS Everywhere You Can.
HTTPS works anywhere, use it—and HTTPS Everywhere, from the Electronic Frontier Foundation—can make sure you do. Of course, not every site supports it, but if it’s available, the add-on will try to take you to the secure version of the site, and if it’s not there, you’ll roll back to the plain HTTP version.
9. Use VPN’s.
The best protection from an untrusted network, is direct encrypted access to a trusted one. That means using a VPN when you’re out and about. Whether you use a third-party VPN service provider or you roll your own VPN at home and connect to it when you’re out and about, using one makes sure that all of your data is encrypted between you and the service provider, locking out anyone on the same network as you who might be snooping around.
10. Use Your Own Wi-Fi Instead.
The real best protection from an untrusted network is not using it at all. Of course, this isn’t a real way to make public Wi-Fi any safer, but if you can, consider ditching the public Wi-Fi entirely and bringing your own. Whether you use a mobile hotspot or smartphone and use your wireless carrier’s data. Of course, prices can vary.
