Although data plans are increasingly accessible, there are many users who still rely on Wi-Fi networks to connect to the internet. When connecting to a public network, some precautions must be taken to ensure that your smartphone remains secure. Check out some tips below:
What are the risks of public Wi-Fi?
The biggest danger of an open connection is exposing your data to other people. Wi-Fi networks that do not have security keys, the so-called WEP, WPA and WPA2 protocols, which are basically the passwords we use on routers, are more susceptible to attacks, becoming easy targets for an attacker to create an access point between your smartphone and the router, tracking passwords and other sensitive user information.
In these cases, it is best to prioritize networks that have some type of authentication. In areas such as shopping centers or airports, for example, Wi-Fi generally allows the user to use the signal by logging in to some social network like Facebook or Google. Although it is safer, there is still a possibility of hacking through these services, even stealing your social network passwords.
Use a VPN
There are some alternatives to reduce the risks of using public Wi-Fi. The best one is to use a good VPN service, so-called “virtual private networks”, applications that encrypt your internet traffic by hiding your device’s IP address.
There are several VPN options available on Google Play and App Store. Free services usually limit your access speed as a trade-off. For fast access, it's worth it, but if you need something with more power, it's best to opt for a paid service. In these cases, compare it with the costs of a mobile network plan, which will probably be cheaper.
Despite this, VPNs also have other advantages, such as the option to mask your connection through ports in other countries. This feature can be useful for accessing content blocked in Brazil, such as streaming catalog from other locations.
Check if the websites you access have an SSL connection
Another important precaution is to check the integrity of the websites you access. This is a rule that does not apply to public Wi-Fi, but applies to any connection. To do this, check whether the address you access has “https” protocols in its domain, which can also be indicated by the image of a padlock in the browser’s address bar.
The presence of this protocol ensures that the portal accessed has an encryption layer to protect your data. Under no circumstances log in or share information with portals that do not have this certification.
Furthermore, the best precaution is always to be cautious. Avoid spending too much time on the open network and disconnect your smartphone when you are not using it.
