You are away from home, urgently need to check something in the mail, Twitter, etc., and you just finished a data packet. You start searching the Wi-Fi network and find a few that do not have security. "If someone has not secured it himself asks to use" - think. In this way naraziliście to steal data, and may even threaten you to legal consequences.
For part of the "free" (ie unsecured) Wi-Fi networks are hidden crooks. Using misleading names SSID, for example, various shops, encouraged to connect to. Then simply check the mail, a purchase order status, and there is a high probability that the data will be captured. If it turns out that the stolen information about the email and password are used in many other sites, we can get into a lot of trouble. Starting from (writing slightly) indecent content, which may appear on our social media accounts, and news for employers, which cause the boss. Not to mention here is to gain access to banks and other institutions that have to do with our finances.
Even if, however, the owner of "free" network is not scammer, we still do not feel safe. In the worst case, one fine day, you will get a letter with a subpoena. It is so next time pożądnie think, it will use the "free" Wi-Fi.
What if we are the owners of such unsecured access point?
Also, it can bring us trouble. To illustrate: Suppose that our unsecured network will connect, for example, a pedophile. After some time knocking on our police with a warrant of arrest on charges of publishing on the web of illegal content. We are charged, as police experts identify the IP address of the network, which used a pedophile. And we still are the owners of the network. Of course, in the end probably will stay acquitted, after the specialized expertise, but certainly lose a lot of time, nerves, which could still be avoided.
Yeah, so how secure your network?
First of all, set a password (difficult to break) on your network encrypted best WPA2-PSK. The next step would be to disable the broadcast identifier (SSID). Finally, we also enable filtering device according to known MAC addresses.
