Wireless Encryption WEP WPA and WPA2
Many wireless users do not know WEP WPA WPA2 wireless encryption protocols and the security threats that may be subject while accessing a wireless network.
When users set wireless network passwords with WEP WPA WPA2 Wireless encryption protocol, users tend to think they are immune from hackers. However, hackers can easily get to their access and download a high potential of information about the user or human capital.
Besides, the collected data may be used by hackers for their advantage while the right user pays.
Types of wireless security encryption
There are some basic security measures listed below that you can take; but first, you may want to learn about Wireless Encryption WEP WPA and WPA2 and the difference between wireless security encryption protocols.
Moreover, it also introduced the CCMP (Counter Cipher Mode Protocol) which is a protocol encryption focused on wireless networks products that apply the IEEE802.11i safety standards to the original standard IEEE802.11.
The use of CCMP against the use of TKIP (Temporal Key Integrity Protocol) encryption is an improved data encapsulation mechanism oriented to the confidentiality of data based on the counter mode with CBC-MAC (CCM) of the AES standard. It was created to address the vulnerabilities presented by WEP, currently insecure.
In the current scenario the use of WPA2 system can be the way to make the network more secure.
WPA is an improved WEP that became available in 2003 after a year of official retirement by WEP.
The increase from 64-bit and 128-bit to 256-bit WPA makes a difference in the method and how Encryption keys are used.
Message integrity check and TKIP (Temporal Key Integrity Protocol) was another change later introduced in the WPA in terms of integrity and intrusion check, providing more security for the user.
However, despite the innovations, WPA still presents some flaws, and thus still prone to hacking, but not so easily as in the case of WEP.
List of measures
Below I present a list of measures that can be taken to protect the wireless network:
- Router Firmware
Using the latest Router Firmware can play a very crucial part in securing the wireless network. Use the latest updated firmware versions in providing protection against hackers.
- Establish Strong Passwords
Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. It estimates how many trials an attacker who does not have direct access to the password would need, to guess it correctly.
Even if you are using the most secure encryption you can become an easy target with a weak password.
The strength of password is the result of its length, unpredictability and complexity. The best password security policy is a combination of capital and lower case letters, numbers and symbols and minimum 8 characters long.
- SSID Name
Many users ignore the importance of changing the name of the used network. However, keeping the same name of the wireless network (system default), help the discovery of network access password, using its name and the use of tools available on the Internet.
If you suspect that there was an intrusion in your network, you should contact IT Specialists about systems & network administration to perform the necessary procedures to safeguard your data.
Actually, companies that have already implemented wireless networks usually have concerns about the security of your data and their human capital.
Often they move away from the wireless network technology with the obvious prejudice on their productivity and infrastructure that may no longer hold.
Many alternatives have been available, as well as technology that allowed greater reliability and higher speeds, existing today many standards and updates to protect wireless transmissions.
The most recent security wireless protocols including WPA2, based on the IEEE_802.1X standard, help provide the best protection for trafficking in the business environment of a medium enterprise. Current standards, when configured correctly (DNS/DHCP/Radius servers, VLAN, AP, IEEE_802.1X protocol, network devices and other components) are very safe and can be used with a high level of confidence in the business environment of a small/medium company at low cost.
