Implementing Wireless Security tutorials

  • With increasing organization going wireless network, itís time to discuss about.

  • Wireless Networks.

  • Wireless Network Technologies.

  • What is Wireless Broadband.

  • Security protocols for Wireless Network.

  • A wireless network as name suggests connect devices using Radio signals instead of wires or cables.

  • A wireless network provides more flexibility, mobility and convince to user.

  • You can create public network where guest can use Internet connection without creating security issue.

  • Wireless network technologies have evolved tremendously and many organizations from large to small scale today rely upon wireless network.

Advantages of wireless network

Disadvantages of wireless network

Convenient to extend network, sometimes it is difficult or impossible to lay cables by drilling holes and pull cables through walls and ceilings.

Wireless network poses serious security threats. As signals are spread in the air, it is convenient for hackers to heck into network.

Wireless network provide portability. The mobility of laptop and smart devices is enabling people to work from wherever there is wireless connection.

Needs very tight security so that unauthorized user cannot exploit situation.

 

Increase productivity for mobile employees.

Common users might not be aware of ways to address security matters. So it requires additional cost for security expert.

Easy to add new devices as no cables required.

Wireless network could be significantly slower than wired network.

Helps to create internet access in public places like Airport, Education camps, Library. You can enables your guest to have internet connection without causing possible security issues to your corporate network.

Wireless reception may be impaired by number of factors such as distance and interference from physical and electrical signal from codeless phone, Bluetooth device or any other wireless devices.

 

Wireless Network Modes

A wireless network operates in two modes.

1) Ad-Hoc Mode

2) Infrastructure Mode

 

Ad-hoc Mode

  • In this mode, two wireless network Adapters are connected directly to each one. Instead of using router or WAP (Wireless Access Point) devices are connected directly to each other. It is also known as peer to peer communication.

  • To reach internet or another network, you must configure one of the peer-to-peer computers as a router that connects to the network.

  • It is typically used to share files, video and internet connection among multiple computers and devices.

  • Young generation with latest smart devices know this technology by name of Tethering or Portable hotspot.

 

Infrastructure Mode

  • In this mode network adapters connect only to special radio bridges or WAP (Wireless Access Point).

  • You need to setup WAP connections using Wireless Routers.

  • Business units and Home network typically uses this mode for setting Wireless Access Point.
