7 techniques to improve wireless network security settings

The use of a large number of wireless networks, it has also brought a wireless network security issues. As wireless networks different from the cable network node physical access control, wireless network security issues more worthy of our attention.

For those using the wireless network, we can click through several aspects of the wireless network set up to improve the security.

1. Close unauthorized access

Guarantee the safety of wireless access points, the key is to prohibit unauthorized users access the network. In other words, the safety of access points to non-authorized users are closed.

2. Where to place the antenna

Wireless access points so that the first step in maintaining the closure is the right place the antenna, thus limiting the scope to reach the effective antenna signal of. Do not place the antenna near a window, because the glass can not stop the wireless signal. Antenna placement is the ideal goal of covering the central region, and leaked to the wall as far as possible the signal less. However, the full control of the wireless signal is almost impossible, therefore, need to take other measures to ensure network security.

3. The use of wireless encryption protocol

Wireless encryption protocol (WEP) wireless network is encrypted information on a standard method.

4. Change the service set identifier and SSID broadcasting ban

Service Set Identifier (SSID) is the identity of wireless access identifier, users and use it to establish a link between access points. This is the identifier as communications equipment manufacturers settings and each manufacturers have used their default values. You need to give you every wireless access point to set up a unique and difficult to speculate the SSID.

5. Disable Dynamic Host Configuration Protocol

This is like a strange security strategy, but the wireless network, it is justified. Through this strategy, you will force the hacker to crack your IP address, subnet mask, and other necessary TCP / IP parameters. Even if hackers can use your wireless access point, he will also need to know your IP address.

6. SNMP settings to disable or modify

If you have a wireless access point support SNMP, then you need to disable it or change the default public and private identifiers. If you do not do so, hackers will be able to use SNMP on your network access to important information.

7. The use of a list

To better protect your network, as far as possible to set up a visit to the list. However, not all wireless access points support this feature. If you can do so, you can specify a certain machine has access to access points. Support the function of access points sometimes use TFTP (simple file transfer protocol) to download updated regularly visit the list, thus avoiding the need to list all the equipment to keep pace on the management of the enormous trouble.
