Wireless network security settings: DHCP function

DHCP is DynamicHostConfigurationProtocol (dynamic host allocation protocol) abbreviation, the main function is to help the user randomly assigned IP address, without the user manually sets the IP address, subnet mask, and other TCP/IP parameters needed. This is a user-friendly functionality, but it was a lot of people with ulterior motives. General router DHCP feature is turned on by default so that all the signal range of wireless devices are automatically assigned to the IP address, which left a great security risk. An attacker can use assigned IP addresses easily get a lot of your router, so disable the DHCP function is necessary.

Wireless network security settings II: encryption

Now a lot of wireless router has a wireless encryption, which is the wireless router's important protection measures, through radio waves of data encryption to ensure secure transmission of data. In General, a wireless router or access point has a WEP encryption and WPA encryption, WEP typically include 64-bit and 128-bit two encryption type, as long as you enter 10 or 26 hexadecimal string as the encryption password to protect your wireless network. WEP Protocol is on in both devices wirelessly transmitted data is encrypted manner to prevent the illegal invasion of user eavesdropping or wireless network, but the WEP key is saved in Flash, so some hacker can exploit vulnerabilities in your network easily into your network.

WEP encryption occurs earlier and now almost all have been upgraded to WPA encryption, WPA is a standards-based interoperable solutions for WLAN security enhancement, you can greatly enhance an existing WLAN system of data protection and access control level; WPA strengthened generated encryption key algorithm, the hackers even if group information collected and its analysis, it is almost impossible to figure out a common key. The emergence of WPA allows network more secure and reliable.

Wireless network security settings: SSID broadcast

In short, the SSID will be your own wireless network the name. In the search for a wireless network, your network name will be displayed in the search results. Once attackers leverage common initialization string to connect to a wireless network, very easy intrusion to your wireless network, so I strongly recommend that you turn off SSID broadcast.

Also note that due to the specific type of access point or router's default SSID on the Internet can easily be found, such as "netgear, linksys, and so on," and therefore must be replaced as soon as possible. For most families, choice of naming differences larger.

Turn off SSID, then searching for wireless networks you will find in the absence of an SSID broadcasting, the wireless network is a wireless network adapter to ignore, especially when using WindowsXP manage wireless networks, you can achieve the purpose of the "up", so that the wireless network. But turn off SSID makes network efficiency slightly lower, but will greatly improve the security, so turn off SSID broadcasting still very worthwhile.

Wireless network security settings four: IP filtering and MAC address list

Since each network adapter's MAC address is unique, so you can set up a MAC address list to improve security. In the enabled IP address filtering, only the IP address in the list of MAC users can access the wireless network, the other is not in the list of natural cannot connect to the network. Also note in the "filter rule" be sure to select "allow only the MAC address of the list established in force and the MAC address of the access to the wireless network" option, or wireless router will block all users connected to the network. For home users, this approach is practical, the family has a few computers in the list you can add several pieces, so that both can avoid neighbor "rub network," you can prevent an attacker from invasion.

Wireless network security settings in five: initiative update

Search for and install the wireless router or wireless network adapter of the latest firmware or driver updates, elimination of previously existing vulnerabilities. Also download and install the operating system in an update on the wireless features, such as WindowsXPSP3 or VistaSP1, and so on, so you can better support the use of the wireless network and security, make their own devices to have the latest features.

Wireless network at an increasing rate, wireless networks also the increasing security. In fact, as long as the simple few settings can improve your security level. Wireless network environment is not connected, the security work to home to make the use more peace of mind carefree.
