Public Wi-Fi networks are extremely dangerous to their users. There are thousands of victims and many hacking incidents occur in places with free shared networks. Most open networks, whether in cafes or public places, are always at risk of total penetration. And penetrate your phone or computer very easily! Wi-Fi is less secure than your personal network, because you do not know who set it up or who’s calling it. It is best to use your smartphone as a point of contact instead, but if you have to use it you can still reduce its damage by following these simple steps:
Protect yourself on public Wi-Fi networks
1. Do not trust any network, especially networks that are open to the public
Public Wi-Fi networks are a disaster for your security and privacy. Data sent and received is not encrypted, so you can easily be vulnerable to hacking, so wherever you can stick to known networks and if you can stick to a few public Wi-Fi networks as much as possible, the more networks you log on to, the more likely you will be to stumble into one that you steal into your password, credit card details, and important data.
2. Be sure to browse sites that support the Https encryption protocol
Google Chrome now lets you know when the site you’re visiting uses an unencrypted HTTP connection instead of encrypting HTTPS by marking it as “unsafe” earlier, and this warning is very important to users of public Wi-Fi networks.
When you upload a Web site that uses an HTTP protocol, your connection to the site is not encrypted. This means that anyone on the network can view your information or even modify the contents of the site before it reaches you, but using HTTPS your connection to the site is encrypted. Passwords or credit card information – are protected when they are sent to the site.
3. Do not give too much information about these networks
Be very wary of signing up when you are connected to a public Wi-Fi network. If you are prompted for a set of personal data, such as your email address or phone number, if you are absolutely forced to connect to such networks, consider using alternative data such as an alternate email address.
4. Disable file sharing properties as File Sharing and AirDrop
When you use a public network, you will need to modify some features to protect you, such as file sharing features, and you can do this if you are a Windows user by going to Network and Sharing Center, then changing advanced sharing settings , File and printer sharing.
For users of Mac computers, they can move to System Preferences System Preferences, and then choose to share Sharing, and deselect everything, then went to the Finder, and press AirDrop, and select Allow me discovery by: No one Allow me to be discovered by: No One .
For iOS users, all they have to do is search for AirDrop in the control center and turn it off. So nobody can access your files nearby, or send you malicious files that make it easier to hack your device.
5. Be sure to use VPN services
The most effective way to stay safe on public Wi-Fi networks is to install the VPN on your devices, which will allow you to connect encrypted to another virtual network and then connect to those public networks. It encrypts data sent to and from your laptop or private phone Connecting you to a secure server, making it difficult to know what you are doing on the Internet or getting your private data from other people on the network or anyone who is running the network.
6. Be sure to update your software or any other software
In the next few years, when the WPA3 standard is adopted as the new security protocol for wireless networks, public Wi-Fi networks will provide more built-in protection. Until then, many hackers rely on older versions of the software, so make sure that all software updates are turned on. Laptop or phone before going out, in addition do not download or install anything new on the public Wi-Fi network.
