Information technology has come a long way from it's original configuration just for data entry.
Power, versatility and diversity are key elements that interfered and invaded all sectors of activity from the more minor sectors to the more essential sectors.

For more than twelve hours now the online services, the ATM's and AccèsD are out of order.
These interruptions are due to a fire throughout the electrical system in one of Desjardins supplier's servers rooms.
It's obvious that it only happens to others!

The consequences can be damaging : loss of credibility, loss of clients, frauds, civil action suits, etc... It is unforgivable when solutions are available.

INTRODUCTION TO WPA (WiFi Protected Access)
WPA is a security protocol, proposed by the Wifi Alliance, designed to improve the WEP security features.
WPA is a lighter version of the 802,11i standard. WAP's encryption method is the Temporal Key Integrity Protocol. TKIP scrambles the keys using a hashing algorithm and, by adding an inergrity-checking feature, ensures the keys haven't been tampered with.
WPA depends on a central authentication server such as RADIUS to authenticate each user and their access rights along a specific wireless network. One variation of WPA is called WPA Pre Shared Key or WPA-PSK for short. WPA-PSK is a simplified but still powerful form of WPA most suitable for home WIFI networking and can help you avoid setting up a RADIUS server.


INTRODUCING THE 802.11i STANDARD
The 802.11i standard was rectified on June 24th 2004, to specify security mechanisms for wireless networks. This standard uses the TKIP encryption method also same as the WEP, but equally supports AES (Advanced Encryption Standard).
Therefore the Wi-Fi Alliance created a new certification named WPA2 for equipments that support the 802.11i standard (such as laptops, PDAs, network cards etc...)
Contrary to the WPA, the WPA2 allows users to secure the wireless network whether in infrastructure or ad-hoc mode.

WPAs Architecture
The 802.11i standard defines two operating methods
- WPA Personal : this mode allows for a secured infrastructure on the WPA without having to implement an authentication server. A pre-shared key or pass-phrase put into a PSK form by a hashing algorithm is used for authentication. Unlike with the WEP it is unnecessary to have a specific key length. It is the most likely choice for homes and small offices.
- Enterprise mode: this mode is more difficult to configure, an 802.1 x RADIUS (Remote Authentication Dial-in User Service) server and an Extensible Authentication Protocol (EAP) are used for authentication.Read More ...

They operate at up to 11 megabits ...Read More ...

What is a wireless network?
A wireless network is basically self explanatory. The term is most commonly used to refer to a telecommunication network whose interconnections between terminals (such as computers, laptops, PDAs, etc....) are implemented without the use of any wires.
There are limitations to where you can access a network - you must be within range of an access point and be part of a wireless network that transmits data to your terminal. That is why the term mobility is frequently used when speaking about wireless connections.
Wireless telecommunications networks are generally implemented with some type of information transmission system that uses airwaves (radios, microwaves) instead of standard wires, to carry data from one point to another.
Wireless connections allow for easy communication between equipments from 10 meters up to a few kilometers away. Wireless networks eliminate the hassle of messy cables and other problems that are encountered when using wire communications (such as holes, cable equipment, connectors, etc...).
Wireless connections offer more mobility, the downside is there can sometimes be interference that might block the radio signals from passing through. One way to avoid this is by putting the source of your wireless connection in a place that the signal will have as little interference as possible. Sometimes nearby networks are using the same frequencies, this can also cause interference within the network and can reduce its performance. That is why there are regulations in each country to define the frequencies and power of each category.

Hertzian waves are hard to confine in a restricted geographical area. It is easy for hackers to intercept valuable information if it circulates clearly along these networks ( which is always the case - default setting-). It is fundamental to set up the necessary resources in such a way to insure the confidentiality of data that circulates on these networks.

Wireless Network categories.
We can usually distinguish many different types of wireless network connections depending on the connectivity level of a geographical perimeter (called coverage zone) :
