transmit wireless Internet signals. However, WAP protocol with high security performance is not used to protect wireless signal transmission. Even if common online users use the WEP encryption protocol and WEP key settings, illegal attackers can easily crack encrypted signals through professional attack tools, this allows you to easily intercept information such as the customer's Internet address,

Ordinary Internet users even use the WEP encryption protocol, with WEP key settings, the illegal attacker can still easily decipher the encrypted signal through some professional attack tools, making it very easy to intercept information such as the client's Internet address,

WEP encryption To achieve wireless network security light access control certainly not, data encryption is also essential, data encryption can guarantee that the launch of the data can only be expected to receive and understand the user, the current common methods of data encryption have WEP and so on. WEP (wiredequivalentprivacy) encryption technology is derived from the RSA data encryption technology n

. June 24, 2004, IEEE passed the 802. 11i based on the SIM card authentication and AES encryption method for wireless LAN provides security, making wireless LAN has a more extensive application space. Security mainly includes access control and encryption two parts. Access control guarantees that only authorized users can access sensitive data, and encryption guarantees that only the correct recipient can

Protocol security The extension headers in IPv6 's AH (Authenticationheader) and ESP (encapsulatingsecurity payload) combine a variety of cryptographic algorithms to provide security at the protocol level. As shown in Figure 1 of the actual

Security Settings for home networks are a key issue for us to study. Here we will introduce several tips to help us solve the security problems of wireless networks. Nowadays, most households access the Internet by setting up wireless networks. However, many people know that many network

If enterprises can use hidden danger scanning tools to discover vulnerabilities in the network system, and take appropriate measures to resolve viruses.

Many cutting-edge security technologies are often only understood by a few people within the enterprise, and they lack the means to share these knowledge to improve the overall security level of the enterprise. At present, the security field is becoming larger and smaller, and the experts in

As we all know, in windows, when Apache is installed as a service for the first time, it will run with the user "System" (Local System account. If all the resources of the web server are on the local system, this will have fewer problems, but it will have a lot of security permissions to affect the local machine, therefore, you must never enable the network permissions of the System account!

wireless network. Wireless Networks are exposed. Compared with wired networks, wireless networks rely only on radio waves for transmission and reception. As long as malicious users have certain knowledge about wireless networks, the security of enterprise wireless networks is quite a problem. Intruders can destroy and intrude through highly sensitive receiving devices. The default Wireless LAN has no

protection measure for wireless routers. Data Encryption in radio waves ensures the security of transmitted data information. Generally, wireless routers and APs have the WEP encryption and WPA encryption functions. WEP generally includes 64-bit and 128-bit encryption types, you only need to enter 10 or 26 hexadecimal strings as the encryption password to protect the wireless network. The WEP protocol encr
