In-depth discussion and understanding of the selection of wireless encryption

You certainly won't design an Internet access network without a firewall. Therefore, how do you set up an unencrypted wireless network? Understanding wireless encryption is very important for deploying a secure wireless network.

The security of wireless transmission is similar to a written message. There are various ways to send a written message. Each method provides an enhanced level of security and protects the integrity of this information. You can send a postcard so that this information is made public to everyone who sees it. You can put this information in an envelope to prevent anyone from seeing it at will. If you want to ensure that only the recipient can see this information, you need to encrypt this information and ensure that the recipient knows the decoding method of this information.

This is also true for wireless data transmission. Unencrypted wireless data is transmitted in the air and may be intercepted by any nearby wireless device.

Using the Wired Equivalent protocol (WEP) to encrypt your wireless network provides minimum security, because this encryption is very easy to crack. If you want to protect your wireless data, you need to use more secure encryption methods such as WPA (Wi-Fi protection access. To help you understand these options, we will briefly introduce some existing wireless encryption and security technologies:

Wired Equivalent protocol (WEP ). Wired Equivalent protocol is a type of encryption that manufacturers rush to launch as a pseudo standard. The vendor must rush to produce wireless devices before the Protocol standards are finalized. Therefore, this Protocol later found some vulnerabilities. Even an initial attacker can exploit this Protocol's security vulnerability.
