What is used to secure wireless LANS?

Answer 1

1. Security algorithms like, WEP (Wired Equivalent Privacy) and WPA/WPA2 (WiFi Protected Access) are used for securing Wireless networks.

2.Creating a hidden network is also a good choice because ordinary computer users cannot see hidden networks.It adds an extra layer of protection.

Answer 2

There are several ways to do this but the one that is most commonly used is encryption by use of the WPA2 protocol. There is an earlier version of this called WPA that is not as commonly used now because it has not proven to be as secure as WPA2. WEP, the original wireless encryption protocol, is completely out of vogue at this point in 2014 due to the relative ease by which one can obtain the WEP keycode.

Beyond this, there are settings that can be configured in the router to increase security such as MAC address filtering and time restrictions for access to the network. In a more sophisticated system, one can also set up VLANs, client isolation (which means that every device that attaches to the wireless network can see only itself and the internet but cannot browse the local network), and bandwidth limitations.
