In recent years, IT experts have put a lot of emphasis on the importance of properly securing wireless networks. In fact, while the message has gone over well for wireless, this is far from the case for wired networks as most companies continue to neglect the protection of their LAN network. Companies are unknowingly at increased risk of being attacked or having their sensitive data accessible to anyone with a network connection at their disposal.
Take for example your residential WiFi access. You most likely need a password to connect to the Internet. However, if you connect your workstation directly to your router, authentication is no longer necessary and you have immediate access to your network. This is exactly the same principle for companies. Remote access to the network is secure, but the wired entry doors within the building are unlocked when companies do not impose some form of authentication before a user can connect to the network.
