Cracking into Wi-Fi networks isn't complicated for anyone who really wants to do it, especially if you are only securing your network with WEP encryption. WEP is the most commonly used encryption available on wireless routers, and it only takes a couple searches on YouTube to find tutorials on cracking WEP Wi-Fi networks to gain access in just a few minutes.
Businesses shouldn't use WEP to secure their wireless networks, but instead should at least use WPA or WPA2. If you aren't sure what type of encryption your wireless network is using, contact Manage My IT at 888-505-2880 to make sure you aren't leaving yourself open for localized threats. If you know your Wi-Fi doesn't even have a password, we can enable that security for you.
Once a user can log onto your wireless network, they can start using your internet connection, but from there they could possibly be able to get deeper into your network and cause some real trouble for you. While requiring a long, secure password to log devices onto the network is inconvenient, businesses need to enforce this to prevent sensitive corporate data from getting into the wrong hands.
