The 802.11 wireless networks (Wi-Fi) is one of the best networks. As of it is easy and fast deployment and installation.
There are two modes in which Wireless Network operates:
a) Infrastructure mode:
In this operation mode, each wireless client connects directly to a
central device called Access Point.
b) Ad-hoc mode:
In this operation mode, each wireless client connects directly with
each other. There is no central device managing the connections,
meaning that each wireless client talks to each other freely.
Currently the IEEE 802.11i is the most used security standard released, that is used to protect wireless networks. In case of not using 802.11i standard in wireless network, other security measures like VPN, IPSec, etc can be used.
Some of the suggestions for security measures:
I would suggest using Access control: Registering all the devices which should be connected to network, would ease the given task.
