With the development of network technology, wireless network security has become more and more important. From what perspectives should we set up? Next we will introduce it to you. Why should I disable the network line for wireless network application

skills here are also very useful for IIS administrators with a strong budget. First, develop a set of security policies The first step to protect Web servers is to ensure that the Network Administrator understands every rule in the security policy. If the company's top management does not regard server security as an

can easily bypass the configuration of the corporate firewall. Skype uses 80 and 443 ports, and most firewalls open these ports to allow browsing of the network. In addition, Skype will change the transmission route if the assigned port is not available when the Skype is installed. As a result, Skype's ports can be changed according to demand, making it harder to block Skype with firewalls. Skype also uses a unique AES 256-bit

Is your computer shared with people? If so, you will be concerned about the security of your personal files, and if you are using the Windows XP operating system, you can use some of the simple and efficient settings provided by Windows XP to maintain your file security. 1, how to let XP automatic networking ie--tool--internet Option--Connection, check "network

Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus

The basic principle of HTTPS/SSLSecure Sockets Layer, SSL, is the most common standard for secure communication over the Internet. The WEB application uses HTTPS (SSL-based HTTP) and HTTPS uses digital certificates to ensure secure, encrypted co

take advantage of the vulnerability of the NetBIOS network protocol routine handler OOB to place some specific packets of data OOB on an open port on an IP address (usually 139, 137, 135) , causing your computer to crash suddenly; attacks on Windows 98 systems are primarily for the WINDOWS98 system's own blue-screen vulnerabilities, while Windows 2000 attacks are a number of denial of service vulnerabilities through itself.

Regularly review network entry pointsYour network may constantly change the size and increase the entry point. Therefore, you can regularly check all the ways to access the network in your organization. Be careful with all the entry points. You s

are available: Wired Equivalent privacy protocol (WEP) and Wi-Fi access protection protocol (WPA ). In fact, only one of the protocols can be used at a time. Regular changes to keys may also help protect the network. With any license, you should first choose to use WPA, because WEP may be decrypted by hackers using special software. Strengthen key management Even if the encryption algorithm is used, if the

With the development of technology, the number of technical problems also increases. For wireless networks, improving or improving the security of networks also brings inevitable problems. Here we will introduce them in detail. The extensive use of wireless networks also brings about the security of wireless networks. Because wireless networks are different from wired n
