At present, the security of the Internet is a content that all people should learn. In particular, each home has a router, and more are using a wireless router. That is to say, as long as the wireless router is covered by signals, people will Your router can link, so this site compiles a few points on the router security settings. 1. Turn off unauthorized access The key to ensuring the security of a wireless access point is to prevent unauthorized users from accessing the network. That is, a secure access point is closed to unauthorized users. 2. Antenna Placement The first step in keeping the wireless access point closed is to place the antenna correctly, limiting the amount of signal that can reach the antenna's effective range. Do not place the antenna near a 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 out of the wall is as small as possible. However, it is almost impossible to completely control the wireless signal, so it is also necessary to take other measures at the same time to ensure network security. 3. Using Wireless Encryption Protocols Wireless Encryption Protocol (WEP) is a standard method of encrypting information on wireless networks. 4. Change Service Set Identifier and Disable SSID Broadcast The Service Set Identifier (SSID) is the wireless access identity identifier that the user uses to establish a connection with the access point. This identity identifier is set by the communications device manufacturer, and each vendor uses its own default value. You need to set up a unique and hard to guess SSID for each of your wireless access points. 5. Disabling Dynamic Host Configuration Protocol This seems to be a strange security policy, but it makes sense for wireless networks. With this strategy, you will force hackers to crack your IP address, subnet mask, and other required TCP/IP parameters. Because even if a hacker can use your wireless access point, he still needs to know your IP address. 6. Disabling or Modifying SNMP Settings If your wireless access point supports SNMP, then you need to disable it or modify the default public and private identifiers. If you don't do this, hackers will be able to use SNMP to get important information about your network. 7. Using an Access List To better protect your network, set up an access list as much as possible. However, not all wireless access points support this feature. If you can do this, you can specify that a machine has access to the access point. Access points that support this feature sometimes use TFTP (Trivial File Transfer Protocol) to periodically download updated access lists, thereby avoiding the immense administrative trouble of having to keep the lists on all devices synchronized.
