Alert to expand wireless network coverage of security risk

The following four recommendations to help you in the expansion of network coverage, ensuring its security.

A wireless network coverage means that it can effectively covered area, refers to the ability to effectively access its physical area. In most cases, wireless network coverage is a good thing, even if only used to brag. Greater scope means for network access to more flexible. From a certain standpoint, you want your wireless network range, the better. Obviously, the larger boundaries more area to provide additional availability. On the other hand, the increase in coverage will increase network from malicious attacks. A network coverage more or less affected by the access point configuration. For intruders, enter the first WLAN entrance, of course, is the access point (AP). This is why management network coverage in requires constant on security risk and coverage expanded to two factors. Simply put, the expansion of network coverage will inevitably means that increased security risks. So you in expanding your network, you must remember that for security problems to give sufficient attention. As your network expands, there is some work to be carried out by the system to reduce the informal specification: network expansion when the need to increase the AP should follow the normal procedure for adding them: to increase the coverage of the request. About the AP will handle the user load. For the local environment of exposure and potential signal interference problems do an assessment. Authorizes a person to be responsible for. Install and test on the AP's detailed records. By AP extended wireless network was too easy, so this is a very powerful temptation. But the problem is that if we put our network coverage in your office building, expand a floor that will bring us what kind of problems and risks? control local AP coverage of your networks have coverage, AP. The following are some rules to help you provide better coverage, to prevent information disclosure: as much as possible to let the farther away from the Windows of the AP, the better. In the room, to the extent possible, the AP is installed in the height. Ensure that the AP not and another RF source too close. (The computer itself may cause interference, do not let two AP immediately. Carefully select antenna different) environment for different types of antennas. The principle is that the signal remains in your Office area, in the region to conduct high quality network connections, and in the external, as much as possible to prevent the connection. Here are some good suggestions: for a centralized distribution of AP, with all-directional antennas. Let the antenna straight up. In the Office area surrounding consider using directional antenna to prevent signal leakage. If you can't change a near the Office area surrounding AP antennas, it points to the direction of the Office of regional centres. Maintain appropriate user/AP ratio another control on network coverage is a separate utility of AP. Maintain appropriate user/AP ratio is very important. 20: 1 is I think that's the percentage limit. Remember the valid range for AP, in a physical room, in addition to 150 feet is unlikely to appear signal interference. According to the principles of calculation of the amount required, and AP design their distribution. Written in the last words when you increase the AP signal strength to improve wireless network efficiency, remember to also consider the security issues. Signal increased, in the Office area, of course, you can provide a higher quality of network connections, but at the same time, strengthen the signal may be leaked to the outside of the highway. Attention to these details can help you prevent malicious users from invasion. Remember that illegal AP coverage is not planned, uncontrollable. Control systems theory of axiom is: you can't control what you cannot observe things. As a result of illegal AP may slip into an even design very perfect wireless network, so the solution is to make unremitting efforts to carry out monitoring. You can use many free software to find illegal AP.
