Today everyone has a Wifi network at home and we have seen how important it is to secure the home Wifi network and protect yourself from external intrusions . But how difficult it can be for a person, more or less able to use the computer, to bypass the security of Wifi "> can be violated", but rather of " how long it will take ".
If we wanted to significantly improve the security of the Wi-Fi network, we would have to encrypt and filter everything that passes through it.
For example, you could set up the router to allow access only to a specific VPN server under control, and require each client to authenticate over Wi-Fi throughout the VPN.
So even if Wi-Fi is hacked, there are other layers to overcome.
This is an excessive security system for the vast majority of people, but it is not uncommon to find it in large corporate environments.
A simpler alternative to ensure some security of the home network is to abandon Wi-Fi entirely and go back to the old wired solutions.
This, however, is very limiting, especially if you want to connect a smartphone or tablet to the internet.
The ideal then to mitigate the risks is to reduce the signal strength of the router so that it does not leave the house.
In practice, instead of using methods to amplify the Wifi signal and extend the signal, we reduce it.
To do this I found tricks to limit the signal outside using aluminum nets on the windows (such as mosquito nets).
However, this will also be a shield for the cell phone signal.
Another alternative would be to monitor and record the network traffic passing through the router or, very trivially, regularly check if someone is connected to our wifi.
Beyond the paranoia, however, if you configure your wireless router with a strong password, you shouldn't take any risks.
This is because every method of accessing a wifi network without permits and passwords requires certain requirements that are not exactly easy to find: being close to the router, having programs, knowing how to use them and having time.
It is not important to know if my wifi network can be violated, but rather if someone can have the time and the ability to do it and what problems this could cause me.
Those who live in city buildings with many neighbors may be more exposed to risks and should use the internet more cautiously, checking frequently that everything is fine.
Keep in mind that WPA2 encryption, which uses AES, is the most secure and it is almost impossible for anyone to find the password.
If you want to be calm, however, you should disable WPS (Wireless Protected Setup) the true Achilles heel of network security.
Leave aside the basic techniques such as hiding the SSID (the name of the network from the scans).
The Fitro Mac is not very practical and, as already mentioned, it is a weak protection, even if it can discourage attempts by improvised hackers (maybe kids who try it for fun).
Finally, make sure that the connections to the e-mail address and browsing on sensitive sites are encrypted and impossible to sniff from the outside which is the real risk of wifi networks.
Without knowing any password, in fact, we have already shown how simple it can be to sniff traffic on a network, intercept it and spy on it.
To ensure that internet traffic is encrypted, just check that the sites where private information is entered use the https protocol, visible on the browser's address bar.
