How to protect your wifi – PCWorld

Wi-Fi security has evolved to the point that most modern routers are configured to be secure with strong passwords, encryption methods, built-in firewalls, and other security measures designed to protect you from malicious attacks. But what happens when those encryption methods are broken?

That is exactly what has happened after Belgian researchers at the KU University of Leuven broke the WPA2 security protocol in 2017. WPA2 is used to protect most of the world's Wi-Fi connections because it is the safest method available for use. Overall, so it was great news at the time.

But while the researchers managed to crack the WPA2 protocol, there's little to worry about. Below, we describe all the ways to secure your Wi-Fi network against possible hackers.

How can I protect my data if the wifi is not secure?

The fact that WPA2 has been hacked is alarming news and affects many consumer devices, but there is no reason to panic.

In essence, the researchers exposed a bug in the Wi-Fi standard that leaves wireless traffic vulnerable to eavesdropping with malicious intent.

In other words, anyone could use the bug to see what they are doing on the Internet and get credit card numbers, passwords, chat messages, emails, photos, and more.

The good news is that most of the devices have been patched or updated to correct the error. And in any case, it is not usually only WPA2 that guarantees security between a hacker and your data.

For starters, a Wi-Fi attack must be within range of the network in question, but chances are you're still sending a lot of encrypted information over the Internet, and that's something hackers can't read, even with access to your wifi network

In addition, the https protocol used on many websites adds an extra layer of protection, as would the use of a VPN service like NordVPN or Hidden24. (Read our summary of the best VPNs for more information).

Therefore, you should especially take into account the padlock icon in the address bar of your browser. If the padlock is not visible, indicating that the site is not using https, then there is a chance that any data you enter will be visible to others.

So if you are about to enter your address and payment details and hit submit, make sure the padlock is there first.

Going back to those patches and updates, Microsoft released a fix for Windows devices on October 10, 2017 (which would have been applied if you're using automatic updates). Apple also patched the vulnerability for MacOS and iOS at about the same time.

Google released security updates for Android devices in November 2017, so check the About section of your phone settings or tablet the date of the last security update. If it is before November 2017 and your phone works with Android 6 or earlier, you must update or pick up a new phone.
