"Tolerance": Wireless Network stealth

Wireless Network stealth is a curious word. However, it is also an effective solution to wireless network security. Is it true that I can be as ignorant as Harry Potter? The answer will be announced in this article.

Air is the medium for transmitting wireless signals, which is not limited by space. You only need to be able to connect to the wireless network easily within the coverage of wireless signals. Therefore, wireless networks have more security risks than wired networks. It can be concluded that the security of wireless networks is extremely important. When talking about security, everyone has their own solutions. In wireless networks, the author believes that in addition to regular security measures, computers and routes in the networks should also be hidden to avoid being searched by intruders.

1. Hide a computer

There are many methods to hide your computer. Here we will introduce some common methods.

1. doscommand method. For computers in the LAN, open the Command Prompt window and enter "net config server/hidden: yes" at the prompt to achieve stealth.

2. Cancel sharing. Open the Properties window for the local wireless connection, and select the Microsoft network file and printer sharing option under "Use the following items for this connection" in the "General" tab, then, click the detach button to unmount the file and print sharing service, which can also be invisible.

3. Group Policy method. For Windows 2000/XP users, you can also use group policies. Run "gpedit. msc open the Group Policy, find "Computer Configuration> Windows Settings> Security Settings> Local Policy> User Rights Assignment", and find "Access this computer from network" in the right window ", delete all users.

4. Disable the Ping method. For Windows XP SP2 users, we can also use the firewall to solve this problem. Hacker intrusion usually uses the Ping command to determine whether the host is online. We can Ping him. Go to the control panel, Open Windows Firewall, switch to the "advanced" tab, select wireless connection in "network connection settings", and click "set" to switch the window to "ICMP ", disable both incoming and outgoing requests. When you Ping the server, you cannot determine whether the host is online.

Ii. Hide wireless routes

Many users generally enable SSID broadcast to facilitate client connection. In fact, if the client is relatively fixed, we don't need it at all. We should stop broadcasting it to make it invisible, so as to avoid illegal computer access within the range of signal coverage.

Different devices use the same method to Disable SSID broadcast. You only need to log on to the management interface and find the SSID broadcast settings to disable it. After disabling SSID broadcast, you only need to manually add the first network and enter the SSID name when the client needs to connect.

Although the above method does not absolutely guarantee the security of the wireless network, hiding the corresponding devices will prevent most illegal intrusion.
