When it comes to Wi-Fi security, most of you probably familiar with seeing WPA2. It’s the security protocol you’ve been using since way back in 2004. While this encryption protocol has proved to be robust, and it has gone through multiple upgrades and improvements, it is time to take things to the next level with WPA3.
This new protocol adds multiple changes that serve to make your wireless connection, and more importantly, the data that crosses that connection far safer than it was before. One of the biggest changes is meant to guard against repeated password attacks. If your data is pulled from a network stream and then stored to be accessed offline, the hacker will only get one single attempt at your password. If multiple password attempts are tried, the data will essentially self-destruct, making it useless.
It doesn’t stop brute force attacks on a live connection, but it certainly adds a big barrier for would-be hackers and data thieves.
The Wi-Fi Alliance is also adding forward secrecy measures to the protocol to help combat someone attached to your network. In short, if they capture an encrypted stream today, but then next week finally figure out your password to the network, they still won’t be able to access any of that old data. They will only have access to the fresh data coming across the connection. It doesn’t stop them from getting data, but it limits the damage that can be done.
Of course, the best part about this new protection is it is completely invisible to the user. There will be no changes to how you sign in to your network, or how you set up your passwords. All you need to do is buy a new network router and then any device that supports the new protocol will automatically use the upgraded encryption.
It’s a win-win for everyone.
