No physical node to improve Wireless Network Security Settings

The extensive use of wireless networks also brings about the security of wireless networks. Because wireless networks are different from wired network physical node access controllability, the security of wireless networks deserves our attention.

For the current wireless network, we can improve the security of the wireless network through the following settings.

1. Disable unauthorized access

The key to ensuring the security of wireless access points is to prohibit unauthorized users from accessing the network. That is to say, a secure access point is disabled for unauthorized users.

2. Antenna placement

The first step to keep the Wireless Access Point Closed is to place the antenna correctly, so as to limit the semaphores that can reach the valid range of the antenna. Do not place the antenna close to the window because glass cannot block wireless signals. The ideal position of the antenna is the center of the target coverage area, and the signal leaked to the antenna is as few as possible. However, full control of wireless signals is almost impossible, so other measures need to be taken at the same time to ensure network security.

3. Use wireless encryption protocol

Wireless encryption protocol (WEP) is a standard method for information encryption on wireless networks.

4. Change the Service Set Identifier and Disable SSID Broadcast

The Service Set Identifier (SSID) is the identifier of wireless access. You can use it to establish a connection with the access point. This ID is set by the communication device manufacturer and each vendor uses its own default value. You need to set a unique and unpredictable SSID for each wireless access point.

5. Disable Dynamic Host Configuration Protocol

This seems like a strange security policy, but it makes sense for wireless networks. Through this policy, you will force hackers to crack your IP address, subnet mask, and other necessary TCP/IP parameters. Even if a hacker can use your wireless access point, he must know your IP address.

6. Disable or modify SNMP settings

If Your Wireless Access Point supports SNMP, You need to disable it or modify the default public and private identifiers. If you do not, hackers can use SNMP to obtain important information about your network.

7. Access list

To better protect your network, set an access list as much as possible. However, not all wireless access points support this function. If you can do this, you can specify a machine with the right to access the access point. Access Points that support this function sometimes use TFTP (simple File Transfer Protocol) to regularly download and update the access list, thus avoiding the huge management trouble of keeping the list on all devices synchronized.
