Goodbye to the holes of security of “wi-fi�
A guide of the INTECO teaches to the industralists to avoid imprudences in the installation of the radio networks
With less than one decade of history to its backs, the technology “wi-fiâ€?, based on radio frequencies and microwaves, has been dominated the traditional mesh wirings like means of data transmission. Its popularity between the companies has grown to the same rate that became their multiple advantages public: comfort, rapidity, mobility, total compatibility between devices… All one retahÃla of virtues that has practically been able to darken its weak points, not at all beneficial conjuncture for the users.
In order to avoid risks or, at least, of diminishing them it turns out fundamental to adopt a series of protection measures. The National Institute of Technologies of Comunicación (INTECO) gathers in a guide especially directed to SMEs some of the most effective practices in these cases. The common denominator of all of them, the shield of each one of the steps that are realized at the time of connecting the device to the joining point.
It is not necessary to be an expert to have a safe network “wi-fi�. Whatever it has general knowledge and the manuals of use to the reach can to form one. In this sense, the document contributes five basic recommendations:
1. To plan the reach of the installation. This one has to limit itself to respond to the needs of the company/signature as far as cover and location talks about, being besides third parties. He is preferable that the direct access is in places difficult to manipulate, like false ceilings or boxes with lock, so that it is not at the disposal of anyone.
2. To change the access data when “router�. It is not necessary to forget to change to the passwords of administration and configuration that bring by defect these devices. The user must replace them by who only he knows.
3. To hide the name of the network, also known like SSID. With this simple step, that does not know the denomination beforehand assigned will not be able to be connected.
4. To use security protocols that allow the coding based on a password. Thus they protect so much the connection as the communications between terminals. Most habitual they are the WEP (simpler and vulnerable) and the WPA (more robust, although not supported by all the systems).
5. To extinguish “to router� when one is not going away to use. Interrupted the connection, the probabilities of success of any attack are diminished.
