Safety and protection analytical measures for wireless router
The wireless network security, in the developed society has become more and more important, whether in the family or business users, the network information safety is always first solve the problem.
The wireless network security, in the developed society has become more and more important, whether in the family or business users, the network information safety is always first solve the problem. Due to a wireless network in relative to the wired network security has inherent disadvantages, so we should learn how to protect their information security.
Wireless router has gradually become the preferred user, many families formed an important equipment, wireless network cable and its randomness, compared with flexibility is the main advantage, ordinary users at home and family by wireless router anytime, access to the Internet. But because wireless network itself is open, so it is difficult to ensure safety.
Now each big brands in wireless router configuration design increases the keys, prohibit SSID broadcasting, to protect individual users of wireless network security. But these protection means what effect it with or its? Today, the author simply talk this aspect.
1. The Wireless Encryption
First, the said wireless encryption is currently the most common way to protect a means, the user can through wireless router WEB interface to encrypt a wireless network Settings. At present, the wireless router or AP encryption type usually have two kinds, namely 64-bit and secure 128-bit encryption type, as long as the input of 10 or respectively 26 string as encrypted password can protect the wireless network. Here to remind, general wireless router in the factory is closed wireless encryption functionality, if you bring direct use of words, so your network is an extremely unsafe network, therefore suggest or Settings again after use.
The author then use a 64-bit mode, use the encryption software that can bring notebook, but due to signal no password, so not connected network. In addition, suggest users password best high safety coefficient contains some, such as digital, characters, characters and formula, etc.
2. Close a DHCP Server
DHCP function is for the computer automatically assigned LAN IP address, so the user manual Settings from IP address, subnet mask and other needed TCP/IP parameters. But because the DHCP, function is to open in signal coverage is any computer can get IP address, illegal users of the wireless network connected to a wireless network, which brings safety hazard. Therefore, disable DHCP function also is a kind of relatively effective safety protective measures.
Disable SSID broadcasting
SSID simple, is you for your wireless network by name, but because of the same products factory of SSID is same, this will give some illegal personal opportunities, through the initial string to connect to wireless networks, so you will receive a wireless network intrusion, safety coefficient of illegal reduced greatly. So close SSID broadcasting function, is necessary.
In addition, closed SSID broadcasting will not affect the use, but in others’ search signal menu will not show your SSID Ming. Unable to find in signal search menu, so can effectively avoid illegal users invasion.
Open IP address, IPMAC address filtering
Enable wireless router IP address filtering, only the IP address in the list of user access to normal, and other wireless network is connected to networks can list. But should notice, in “filtering rules” must choose “only allowed a MAC address list has visited the MAC address wireless network” option, or wireless router will stop all users connected to networks,
Additionally, if in the wireless LAN banned DHCP function, suggest you use wireless services for each of the computer has been set a fixed IP address, then will the IP address all input IP address list of allowed. It can effectively protect the wireless network security.
Summary:
The wireless network security, in the developed society has become more and more important, whether in the family or business users, the network information safety is always first solve the problem. Due to a wireless network in relative to the wired network security has inherent disadvantages, so we should learn how to protect their information security. Today, the author simply talked about the most commonly used several measures, although not so profound, but against the general situation, you still enough to interest can pay more attention to the aspects of books.
