Wireless security protocol driver

In , it became apparent that WEP was not as effective as developers had stated when the massive cyberattack against TJ. Maxx was launched. The original model used a bit encryption key, though it has been upgraded to a bit key that is manually entered by the administrator.

This makes the encryption easier to hack. WEP might have been the original algorithm for wireless networks, but over time it has shown that it is vulnerable to cyberattacks. This is why other security protocols have been developed since the issues with WEP were discovered. Once the flaws were discovered, and made public, in WEP the process to create a new wireless protocol was started.

However, it takes time to write a replacement. To ensure that wireless network users still had protection, the Wi-Fi Alliance released WPA as a temporary replacement in It has discrete modes for personal and business use for improved security.

In personal mode, preshared keys are used to make it easier to implement and manage the network among employees and consumers. Business or enterprise mode requires an administrator to authenticate a device before it can access the network.

This allows larger companies to have more control over who has access to the data. This includes,. Since WPA was designed to be compatible with WEP, IT professionals found that they could easily update to the interim security protocol for their wireless network. All they needed was a simple firmware update. While switching protocols was simple this also created potential security risks since it was not as comprehensive as developers and users hoped it would be.

There are still some security vulnerabilities with WPA2, but it is still considered one of the most secure wireless network protocols available for personal and business use. WPA2 also has several security improvements. These include,. WPA2 also allows for more seamless roaming from one access point to another without having to re-authenticate user access.

This can improve productivity and client relations. Data can be transferred seamlessly, without having to take extra authentication steps. Knowing which protocol provides the best wireless security is helpful, but so is knowing exactly how it works. Wireless security protocols basically encrypt data from senders until the message reaches the receiver. Instead of using secret handshakes and coded messages, the wireless security protocol uses encryption keys. With a possible trillion key combinations, it is almost impossible for hackers to enter the system and get access to the data.

While this does sound like an impenetrable security system, there are some vulnerabilities. With its larger IV size to prevent key reuse and other improvements, companies and individuals began to believe that their wireless networks were safe. In , this changed when a vulnerability in the protocol was discovered. Hackers could take advantage of a system weakness by posing as an access point. This vulnerability did cause concern with wireless network uses, and patches were created to prevent data from being stolen.

The only problem with this remedy is that not everyone may have gotten the patches installed in time or even be aware that their wireless network might be at risk. This particularly applies to public wi-fi hotspots and companies with older networks. The various security protocols for wireless networks use different methods to encrypt messages.

We don't recommend changing this setting unless you:. Wider channel width allows higher performance. For optimal performance and compatibility, enable support for all channel widths. This setting controls the type of Wi-Fi devices For optimal performance and compatibility, enable support for all wireless modes.
