In order to facilitate resource sharing, wireless, print, mobile office operation, we only consume a few hundred bucks to buy a common wireless router and a .wireless device, you can quickly set up a simple wireless LAN network. However, low grade wireless LAN network continues to spread, it is easy for your organization's information security threats are not small. In this case, we can resolve the low grade of wireless .network security threats, and enjoy the fast, convenient network? <br> <br> Low level network security ills <br> <br> Wirelessly connect to community broadband network, and through broadband networks for shared access to the Internet network environment, we .often just by ordinary twisted pair will low wireless router WAN port and community broadband network switch ports, and then reference manual on wireless router connection port parameters for the appropriate settings, you can access the Internet. Because by default, the low range of the wireless .router will automatically enable DHCP service functions, when we add a wireless network adapter devices correctly installed on the computer, do not require any parameter is set to automatic connection to a wireless LAN network. However, in the enjoyment of networking facilities, low grade wireless .router's signal coverage and support the longest transmission distance up to 300 meters, if not taken security measures to prevent, at 300 meters within the installed wireless adapter device of ordinary computers can automatically join local wireless LAN network, then the local wireless local area network is .vulnerable to illegal attacks. <br> <br> Moment, the formation of convenient low grade wireless LAN exist following some security flaws: <br> <br> 1, the security mechanism is not very sound <br> <br> Low grade .wireless LAN are mostly adopted the safety performance of a general agreement to WEP on wireless Internet signal is encrypted transmission, without selection of the safety performance of the higher the WAP protocol to protect the transmission of wireless signals. Ordinary Internet users, even if using WEP .encryption protocol, WEP key, the attacker can still illegally by some professional attack tools to easily decipher the encrypted signal, thereby easily intercept customers Internet addresses, network identification name, wireless channel information, WEP key content and other information, with this information in hand ., the attacker can easily on a local wireless LAN network for theft, privacy, or other unlawful invasion operations. <br> <br> In addition, low grade wireless LAN almost do not support system log management, intrusion detection and other security features, .you can say that the current low grade wireless LAN Security also not quite perfect. <br> <br> 2, no physical isolation <br> <br> Low grade wireless LAN from forming successful at that moment, it is directly exposed to the .outside world, wireless network access could be any valid physical isolation, intentional, unintentional illegal attack at any time exists, then the wireless LAN in all kinds of private information will always be stealing, sniggering. <br> <br> 3. user safety .awareness is not enough <br> <br> Low grade wireless LAN often only support simple address binding, address filtering and encrypted transmission function, these basic security features in the presence of illegal attacker almost no preventive effect. However, some less familiar with wireless .network knowledge of users in order to be able to quickly implement Mobile Office, resource sharing, and other purposes, often will not hesitate to use network management and maintenance of low-cost, easy operation and low grade wireless LAN, wireless LAN Security how to .believe these primary Internet users almost never make any consideration. Coupled with these not-too-familiar with wireless network knowledge of novice, on network security knowledge to understand even less, these users are using wireless networks with very little sense to go for some security .settings. <br> <br> 4. poor resistance to outside interference <br> <br> Wireless LAN in the work process, tend to use a specific working band, the work in the same band wireless network too much, the signal coverage .will overlap each other, it would seriously affect the efficient signal strength, may ultimately affect the wireless LAN signal transmission stability; in addition, the wireless Internet signal during the transfer process, are particularly vulnerable to the wall of the building blocks or interference, this .will cause the stability of wireless local area network. For those of low grades of wireless local area network, its resistance to outside interference ability is even worse, it is clear that such a wireless LAN is unable to meet the high quality network access application requirements .. <br> <br> Networking facilitated by security threats <br> <br> Since low grade wireless LAN exist above some security flaws, these evils if sudden attack or unauthorized attackers exploit, then you may give us a lot of security threats: .<br> <br> 1, resulting in the leakage of private information <br> <br> Sometimes, many wireless LAN Internet users in order to facilitate the work, often inadvertently set units of important privacy information or core work information, even some .areas belonging to the top secret information from a mobile device to hang on the wireless LAN network, making it easy to occur imperceptibly important privacyThe risk of information leakage, serious time to give the unit or individual cause great economic losses. <br> <br .> 2, reduce intranet security capabilities <br> <br> Unit wireless LAN nearby sometimes exist some household wireless local area network or other units of wireless local area network, the wireless LAN is often used to share access to mobile office or Internet network, .the wireless network users are not enough security awareness, and their application to the requirements of the wireless network is not very high, it has to do some of the wireless Internet access and security settings. In this case, the organization any computer with a wireless .network adapter devices notebooks are also likely to automatically connect to other wireless local area network, it is prone to this unit of the wireless LAN and other units of wireless LAN direct Internet phenomenon, even possible unit wireless LAN network interconnect directly with the Internet, these .phenomena clearly reduces the unit intranet security prevention capacity, easy to unit caused serious security ramifications. <br> <br> 3, endangering the security of information systems <br> <br> Considering the low grade wireless LAN low-cost, no need .for complicated wiring, and managing maintenance is also very convenient, if safety awareness is not in place, then a smaller unit is most likely due to technical, cost and other factors, to choose some cheap, poor quality of the wireless network devices in network .upgrade, information point, set up by the network devices and network will be natural exposure to the outside world, wireless network access cannot be effective physical separation, then your organization's information systems security will be compromised at any time. <br> <br> .Resolve wireless network security threats <br> <br> Although low grade wireless LAN easily bring us all kinds of unexpected security threats to your organization's information systems do not small security risk, but for those who have security requirements is not very high, small- .scale units, you can still use a low grade of wireless local area network, after all, this type of networking costs very low, more importantly, through the development of effective measures can be low grade wireless LAN security threat reduced to a minimum, make .small unit users can freely enjoy networking facilities. <br> <br> 1, to check to security <br> <br> In order to keep informed of units the security status of your wireless network, we should periodically on the unit's intranet, .extranet usage and core network equipment for operation in more detail check and do a thorough inspection records. At the same time, we also should increase its efforts on the unit near the area of wireless LAN wireless network to work environment monitoring the trends of the time .also need to be on the Organization's network security assessment and audit; in addition, related to the core privacy information in the units, as well as important application in the workplace network, should be promptly taken to electromagnetic shielding, and other means, to prevent .illicit intrusion or attack. <br> <br> 2. to promote the safe <br> <br> Because of the low grade wireless LAN easily affect internal network security, the owner must prepare a rich range of network security information in the units ., under the regular wireless Internet security knowledge, advocacy, training, in order to strengthen every wireless Internet users' security awareness, at the same time it is necessary to conduct network security special rectification work to ensure that all employees unit in thought attaches great importance .to the wireless network security. <br> <br> 3, from management security <br> <br> Saying "no rules, no RADIUS", in order to guarantee the use of wireless LAN security, we also want to use wireless network .devices to make reasonable provisions for wireless Internet users to conduct reasonably management and unified specification wireless network device mode and security settings, clear the use of the Internet users and access rights; for example, prohibited save important company information for laptops to connect to a wireless .local area network, prohibition of the arbitrary in wireless LAN for shared access to prohibit mobile devices randomly hanging on a wireless local area network, storage, processing core information workplaces must shield protection. <br> <br> Believe in clearly recognizes the existence of .low grade wireless LAN security threats of all kinds, we just take effective security measures to prevent or to enjoy the convenience of wireless network so that low grade wireless LAN also can provide us with the "service". <br>.
