TKIP vs AESTKIP and AES are two separate forms of encryption that can be utilized by a wifi network. So we now have different security modes that we need to know so we can choose the best one for our setup. Of course security encryption has evolved over the years so we want to make sure that the encryption level that we're using is as secure as it can be.

That password is the key to completing the encryption process and securing all subsequent communication between your device and the router. When you then tap on one of those options it will likely then ask you for a password before you can join up. These options are the different routers around you that are broadcasting that they have a wireless network ready for use. You open up the wireless networks option on your laptop, tablet, or phone and lo and behold find a few different options. You're at a new location and want see if they have wifi. This encryption happens when you first establish a connection with a wireless network and your device and the router decide on the encryption type they'll be using for the duration of the connection. Wireless EncryptionWhen you talk about securing a wireless network, you're actually talking about how a wireless network is encrypted. We're going to break it down for you real quick so you're ready to make the right choice for your network. If you haven't been keeping up with wifi security standards it can all seem like a bit of a different language. This level of security was extremely vulnerable to cracking exploits long before the Air-crack-ptw demonstration.When setting up a new wireless router you have a few different options when it comes to the level on encryption you'll be using to secure your wifi network. Although it's good to start with something, relying on WEP for too long could put your organization at great risk. For example, several retail and inventory companies still use scanners and other devices that only support WEP encryption.
The truth is that many companies will likely continue to use WEP, mainly because they can't afford a WPA upgrade. This new product is more comprehensive than other modules, allowing a company to slowly evolve from WEP to WPA at their own pace. The module uses the AirDefense Enterprise platform with wireless sensors to protect devices from WEP encryption attacks. This doesn't make your traffic private but it will prevent intruders from getting deeper into your network.ĪirDefense, developers of WLAN security products, recently introduced a WEP cloaking module designed to aid companies in preserving the legacy in network devices, offering savings on costly upgrades and training. Another good move involves only permitting anticipated traffic from known users and devices connecting to the server. If more reliable encryption cannot be applied because of finances, it is a good idea to isolate WEP devices on VLAN (virtual local area network) subnets of their own. To effectively limit network exposure, experts recommend totally doing away with WEP and using more proven methods of security, with WPA-PSK being the least level of implementation. However, if a static WEP has been in use for six months, an hour will not greatly impact the window of exposure. WLANs (wireless local area networks) still using WEP keys because of inherited equipment probably aren't using any technologies to automatically refresh the encryption keys.

If an attacker has enough incentive to crack into your network, they usually have at least an hour to spare.
Experts believe that due to existing vulnerabilities in WEP, the new cracking method may actually have little impact.
The most recent scenario employed active packet injection to reduce the time for cracking a key from an hour down to less than a minute. WEP cracking utilities have become much faster and more efficient over the years, drastically reducing the amount of network traffic required to a determine a WEP key. While this new method of cracking network security is unsettling, it should come as to no surprise and serve as a reminder that WEP was never secure from the beginning, the underlying reason why so many companies have turned to more efficient standards such as WPA (Wi-Fi Protected Access) or WPA 2. This new attack is capable of cracking the encryption scheme in as little as 20 seconds. In late 2007, a group of German researchers created a new exploit against WEP using the Aircrack-ptw algorithm. Regardless of the obvious flaws, many companies still use some type of WEP within their networks. This method of encryption has proven to be so vulnerable that several in the industry strongly oppose it. WEP (Wired Equivalent Privacy) has taken most of the brunt when it comes to the issue of wireless security.
